Vehicle-to-Everything (V2X) communication refers to the exchange of information between vehicles (V2V), vehicles and infrastructure (V2I), vehicles and pedestrians (V2P), and vehicles and network/cloud (V2N) using wireless communication technologies. The implementation of V2X in autonomous vehicles can significantly improve their safety and efficiency in a connected and intelligent transportation ecosystem in the following ways:
  1. Enhanced Situational Awareness: V2X enables vehicles to communicate with each other and share real-time information, such as position, speed, acceleration, and intentions. This enhances the vehicle's situational awareness and allows it to anticipate and react to potential hazards or critical events proactively.
  2. Intersection Safety: V2X can improve intersection safety by allowing vehicles to exchange data with traffic signals and infrastructure. This enables vehicles to receive traffic light phase information, optimizing speed, and facilitating cooperative maneuvers, such as platooning and intersection priority management.
  3. Pedestrian Safety: V2P communication enables vehicles to detect and communicate with pedestrians carrying V2X-enabled devices, such as smartphones or wearable sensors. This can alert both the vehicle and pedestrians to potential collisions, reducing accidents involving vulnerable road users.
  4. Cooperative Adaptive Cruise Control (CACC): V2V communication facilitates CACC, enabling vehicles to form platoons and maintain safe and coordinated spacing at high speeds. CACC can enhance traffic flow, reduce congestion, and improve fuel efficiency.
  5. Hazard and Road Condition Warnings: V2X enables vehicles to share data about road conditions, weather, and hazardous events with others on the network. This information can be used to warn nearby vehicles and drivers, helping them adjust their driving behavior and avoid potential dangers.
  6. Preemptive Emergency Braking: V2X allows vehicles to receive emergency braking warnings from other connected vehicles or infrastructure, allowing for preemptive actions and reducing the severity of collisions.
  7. Data Sharing for Traffic Management: V2X communication can provide real-time traffic data to traffic management centers, helping optimize traffic flow, reduce congestion, and improve overall transportation efficiency.
  8. Reducing Carbon Emissions: V2X-enabled vehicles can optimize their routes and speeds based on real-time traffic and road conditions, leading to reduced fuel consumption and greenhouse gas emissions.
Overall, the implementation of V2X communication systems in autonomous vehicles plays a critical role in creating a safer, more efficient, and sustainable transportation ecosystem by promoting cooperative, intelligent, and data-driven interactions between vehicles and the surrounding environment.
Relevant answer
Answer
V2X is a technology that enables vehicles to communicate with other vehicles, infrastructure, pedestrians, and networks in a connected transportation system. V2X can improve autonomous vehicle safety and efficiency in several ways, such as:
  • V2X can provide beyond line-of-sight (BLOS) perception for autonomous vehicles, which means they can receive information about the environment and traffic conditions that are not visible to their onboard sensors. For example, V2X can alert autonomous vehicles about potential hazards, such as a jaywalker, a construction site, or a red light ahead.
  • V2X can enable cooperative planning and control for autonomous vehicles, which means they can coordinate their actions with other vehicles and infrastructure to optimize their routes, speeds, and behaviors. For example, V2X can facilitate cooperative platooning, which is a formation of closely spaced vehicles that can reduce fuel consumption and emissions.
  • V2X can enhance the security and privacy of autonomous vehicles, which means they can protect their data and identity from malicious attacks and unauthorized access. For example, V2X can use encryption, authentication, and verification techniques to ensure the integrity and confidentiality of the communication messages.
  • V2X is an emerging technology that has the potential to revolutionize the field of autonomous driving and make it more safe and efficient.

What is the V2X in 5G?
My friend: Hi Saif, I have a question for you.
Me: Please, go ahead.
My friend: What is V2X?
Me: V2X means a vehicle to everything and as per 3GPP; It has 4 types in 5G which are Vehicle to Vehicle (V2V), Vehicle to Network (V2N), Vehicle to Infrastructure (V2I) and Vehicle to Pedestrian (V2P).
My friend: Can you give me some examples?
Me: Of course, V2V means the transfer of data directly between vehicles, so vehicles can exchange information to avoid the collision. V2I involves the transfer of data between vehicles and Road Side Units (RSU) and RSU are application servers positioned along the road with built-in Base Station functionality so they can communicate directly with passing vehicles. The RSU is aware of the timing used by nearby traffic signals and this timing is provided to vehicles approaching the signals so they can react appropriately. V2N involves the transfer of data between vehicles and the mobile network, e.g. providing Internet connectivity. V2P involves the transfer of data between vehicles and pedestrians for example for pedestrians to provide warnings to drivers.

What happens to the PTPS application in traffic signals of the network when the intersections within it are only 90 to 400 meters far apart which bus stops exist between intersections with a distance of around 40 meters from the intersection?
Relevant answer
Answer
The following are the requirements for applying PTPS in a network of 7 intersections which are around 95 meters to 400 meters far apart from each other:
  • The PTPS devices must be synchronized within 1 microsecond.
  • The PTPS devices must be able to communicate with each other over the air.
  • The PTPS devices must be able to withstand the environmental conditions at the intersections.
The following are some additional considerations for applying PTPS in this network:
  • The PTPS devices should be placed in a central location within each intersection so that they can communicate with each other easily.
  • The PTPS devices should be mounted high enough off the ground so that they are not affected by traffic or other obstructions.
  • The PTPS devices should be protected from the elements, such as rain, snow, and direct sunlight.
With these requirements in mind, PTPS can be a reliable and accurate way to synchronize clocks in a network of 7 intersections. Here are some specific PTPS devices that would be suitable for this network:
  • Microsemi Sync Server S3: This device is a high-performance PTPS clock that can be synchronized within 1 microsecond. It has a range of up to 10 kilometers, making it suitable for the 95- to 400-meter distances between the intersections.
  • Rohde & Schwarz PPSclock 1000: This device is another high-performance PTPS clock that can be synchronized within 1 microsecond. It has a range of up to 1 kilometer, making it suitable for shorter distances between intersections.
  • Time Tec NTP200: This device is a more affordable PTPS clock that can be synchronized within 10 microseconds. It has a range of up to 100 meters, making it suitable for the shortest distances between intersections.
The specific PTPS device that is best for this network will depend on the specific requirements of the network, such as the desired accuracy, range, and budget. You can try any of the above suggestions. Thank you.

Machine learning techniques can be applied to enhance anomaly detection in network traffic in a number of ways. Here are some of the most common methods:
  • Feature extraction: Machine learning algorithms can be used to extract features from network traffic data that can be used to identify anomalies. These features can include things like the source and destination IP addresses, the ports that are being used, the types of packets that are being sent, and the timing of the traffic.
  • Training: Once the features have been extracted, machine learning algorithms can be trained on a dataset of normal and anomalous network traffic. This training process allows the algorithms to learn the patterns that are associated with normal traffic and to identify anomalies that deviate from these patterns.
  • Detection: Once the machine learning algorithms have been trained, they can be used to detect anomalies in real-time network traffic. This can be done by comparing the features of the incoming traffic to the patterns that the algorithms have learned. If the incoming traffic deviates from these patterns, it is classified as an anomaly.
By using machine learning techniques, it is possible to enhance anomaly detection in network traffic and improve cybersecurity defenses. This is because machine learning algorithms can learn to identify patterns in network traffic that are indicative of malicious activity. This can help to identify and prevent cyberattacks before they cause damage.
Here are some of the benefits of using machine learning techniques for anomaly detection in network traffic:
  • Increased accuracy: Machine learning algorithms can be more accurate than traditional anomaly detection methods, such as rule-based systems. This is because machine learning algorithms can learn to identify patterns in network traffic that are indicative of malicious activity, even if these patterns are not explicitly defined.
  • Reduced false positives: Machine learning algorithms can also reduce the number of false positives that are generated by traditional anomaly detection methods. This is because machine learning algorithms are able to learn the patterns that are associated with normal traffic and to ignore traffic that deviates from these patterns but is not malicious.
  • Scalability: Machine learning algorithms can be scaled to handle large amounts of network traffic. This is important for organizations that have a large number of devices and users.
Overall, machine learning techniques can be a powerful tool for enhancing anomaly detection in network traffic and improving cybersecurity defenses.

In the case of standing in public and attempting to stop passers-by to complete a short questionnaire, what is your basic approach? In a previous life, I was a commission salesman, so I know how important it is to make the first utterance out of your mouth the right one if you want people to give you even two seconds of their time, so what tends to work best for collecting data for research? A yes-no question? An open-ended question? A statement about the weather? Asking if they have a couple minutes vs avoiding mentioning time? Here have been some of my attempts, but it's hard to gauge which works best with the few attempts I've made:
  1. Excuse me, do you have a moment to talk (about ...)?
  2. Excuse me, what do you think about ...?
  3. How's it going? Hot today, isn't it?

I want to simulate a grid-road topology (organized streets) with vehicles generate traffic to Road Side Unit (RSUs). Also, if I need to ramp up quickly to 100 or 200 vehicles how can I do that?
Relevant answer
Answer
The simplest way to do this is to use a File-based approach; this approach does not require any modifications to NetSim code. Your program in MATLAB should write the device position with respect to time in a text file. The format is explained in https://www.tetcos.com/help/v13.3/Technology-Libraries/MANETs.html#file_based_mobility_model
In the devices which you wish to move per MATLAB data, set the mobility model to File-Based Mobility and update the Mobility CSV file with input generated from MATLAB in NetSim's mobility file format. The mobility file is common for all devices in the network. Hence, if you want to introduce mobility in multiple nodes based on data from MATLAB all this information can be put together in the same mobility CSV file which NetSim will read at the simulation start.

There is various figures of supply and demand curves in literature that describe induced demand but they do not correspond to the properties of supply and demand of car travel. My question is related to following subquestions: is supply of car travel dependent or independent on price (i.e. is it a vertical line)? Does shift in supply (increase of capacity) lead to shift of demand curve or move along the curve? Move along the curve (which is in the most of the graphs I have found) means that the demand corresponding to a particular price stays the same but it is certainly not true. There is different demand (traffic volume) with the same level of congestion (price/time).

Does collecting waste at night help to reduce the carbon footprint cause I believe at night there won't be much traffic and mostly the street are always empty.
Relevant answer
Answer
Collecting bins at night instead of during the day may have several benefits, but it may not necessarily reduce the carbon footprint. Here are some possible benefits:
  1. Reduced traffic congestion: Collecting bins at night when there is less traffic on the road can reduce traffic congestion and improve the flow of traffic during the day.
  2. Improved air quality: Collecting bins at night can also reduce air pollution during the day, as there will be fewer vehicles on the road emitting exhaust fumes.
  3. Improved safety: Collecting bins at night can reduce the risk of accidents involving waste collection vehicles and other road users during peak traffic hours.
However, it's worth noting that the carbon footprint of waste collection is primarily determined by the type and efficiency of the collection vehicles used and the distance traveled, rather than the time of day the collection takes place. Additionally, if waste collection at night requires additional lighting or energy consumption, it may negate any potential carbon footprint reductions.

I am working on the control of urban traffic networks. I have the urban traffic volume data that consist of attribute like location, route length, number of vehicles per day, ADT, ADTT and so on. How can I determine trip production or trip completion flow using historical data? The network is a large regional network i.e heterogeneous network, that requires partitioning into homogeneous subregions, the second question is how can I partition the urban traffic networks?
Relevant answer
Answer
To determine trip production and completion flows using historical data of an urban traffic network, you need to collect data on traffic volumes, travel times, and origin-destination patterns. Then, develop a trip matrix using a variety of methods such as the gravity model or entropy-maximizing method. Use this matrix to estimate the total number of trips produced and completed within the study area and time period. Analyze flow patterns of trip production and completion to identify spatial or temporal trends or patterns. Validate the results by comparing them to other sources of data such as travel surveys or traffic counts. It is recommended to consult with an expert in traffic engineering or transportation planning to determine appropriate methods and tools.

According to Professor Nilsen of the NHH Norwegian School of Economics, ‘the higher the temperature, the lower the power plant’s efficiency – prices therefore rise in line with the temperature’ – see: https://www.nhh.no/en/nhh-bulletin/article-archive/older-articles/2015/april/powerplants-and-climate/
If I visualise the entry and exit to a power station as similar to a Motorway junction, the speed at which heat molecules move forward depends, like that of cars, on the volume of traffic in front of them.
If the road leading to the motorway junction is reasonably empty, the cars (i.e. heat-molecules) can approach the entrance reasonably fast – if it is full, they have to approach more slowly. Similarly, if the motorway is also blocked with slow-moving traffic, the cars (i.e. heat-molecules) entering it are forced to move slowly.
As the speed of the heat-molecules is what causes the rotation of the turbine which creates the electricity, (and the faster the turbine rotates, the more electricity is created) it can be imagined that the turbine works most efficiently when the air ‘upstream’ and ‘downstream’ from it is relatively empty of heat-molecules – i.e. cold.
Is this correct? Please can you tell me how to find the relevant data?
Relevant answer
Answer
I have been modeling the operation and performance of power plants for almost 50 years and have written numerous articles on the subject. These may be found here on RG and also Google. Whether or not there is global warming or how much this might be is a different question but assuming there is, one could use this in the Carnot formula to get some idea of the possible impact on the efficiency of a power plant. That result will be quite small, regardless of whose numbers you choose. Higher prices for electricity are driven by countless other decisions that people make, including; retirement of assets, maintenance, replacement with green options, which green option to use and when, etc. This book (Computer Simulation of Power Systems) will be free tomorrow (10/7) https://read.amazon.com/kp/embed?asin=B07YJ1JFLS&preview=newtab&linkCode=kpe&ref_=cm_sw_r_kb_dp_GXSACP1BQPFR8GN1YGKS

According to the (UNODC, 2015), illicit drug use is a multi-facet problem which is affects millions of people world-wide. The consumption of illicit drugs has increased over years in the Mauritian population, and it is affecting the population at large, cutting across all age groups and classes, in particular touching the youngsters; presently there is 40% of youngsters aged between 15 and 25 years who consume synthetic drugs in Mauritius (L’Express, 2018). This phenomenon leads to a massive impact to social harm, health issues and economic complications.
The article of Dr. T. Ibrahim and Dr. S. Peerally 2019 sheds light on public health measures that is helpful in tackling the current problem of illicit drug use in the island of Mauritius.
An increase in statistical figures year after year in Mauritius is causing chaos in the population. Institutions like the educational system, the police force and road traffic Management are relentlessly facing real problems like, increased rate of school failures, domestic violence, divorce, road traffic accidents, crime as well as a decrease in the work force of the country (Ibrahim, T. et al. 2019)
The judiciary in Mauritius, relates that from statistics gathered, there is decrease in safety, couple with an increase in criminality rate can precipitate a drop in the amount of tourist and subsequently a drop in the economy of Mauritius. Mauritius depends on the tourist economic as it is one of the main pillars of the island (Ibrahim, T. et al. 2019)
What are the main solutions and alternatives to the combat of Drugs and solutions to eradicate illicit substance in the country ? The Govt and all related institution are merging to only one common problem that is drug.

I'm sure you're still very busy reading all the research papers and articles I referenced in my first reply. Wanted to make sure that I helped you as much as humanly possible. Here's some additional advice.
First, it took me more than 5 minutes to find the paper you refer to by Dr. T. Ibrahim. I find this annoying, but it also doesn't help the scientific processes very much.
This is how you should cite a paper:
Cite as
T. Ibrahim and S. Peerally. (2020). A PUBLIC HEALTH APPROACH TO COMBAT THE PROBLEM OF ILLICIT DRUG USE IN MAURITIUS. https://doi.org/10.5281/zenodo.3687444
Also, you forgot to mention keywords like: Safer Use, Drug Policy, Risk Reduction, Public Health, Evidence Based and Harm Reduction. I'm at least assuming you're not PRO HARM right? And that you did more reading than just the articles that only support your opinion, right?
Finally, please be more respectful to other people. Words like 'addiction' are stigmatizing and unhelpful. Consider phrases like 'drug dependent'. Read more about why/how to write more ethically and humane here: https://www.npr.org/sections/health-shots/2017/06/11/531931490/change-from-addict-to-person-with-an-addiction-is-long-overdue?t=1646374399799 Or even better, buy the AP Style Book from 2017 or later..
Please learn from the mistakes you made in this post. I'm just trying to give some constructive criticism. Nothing personal.

Hi,
Are there proven and emerging technologies for obtaining road network level:
a) motorcyclist traffic volumes (counts)
b) their speeds,
c) motorcycle classification (from light moped to heavy touring bike)?
We have automatic tube counters which can satisfy the first two needs. These are expensive and cumbersome to use on road network scale. Digital video combined with computer vision is emerging quickly and would meet all three needs. The cost is prohibitive.
What other sources and technologies could do a good job and be cost-effective? What is used in your jurisdiction?

For dealing with traffic complications the authorities do not have a magic wand in their hands. But there is always a possibility of improvement. The suave and proficient implementation for mobility of traffic can be accomplished by making best use of the existing system. The proper sign posts, zebra crossing, footpaths, subways and signals are the tools which can be used to transmute commotion into a smooth and effective mobility. We need to take appropriate traffic management measures after trying out their effects. In order to curb the jeopardy of mishaps caused by the maladministration of traffic we need to contemplate abysmally to this nuisance. Due to obliviousness of the rubrics, rowdiness, desertion and waywardness, the roads are wrenching into muddle. The authorities are wedged in torpidity and have no intimation of how to make traffic more affable. Hardly any zebra crossings are visible in Srinagar city. There are no passable parking facilities. The authorities are decreeing conceitedly that considerable challans are imposed on daily basis. Challans will only result in proliferation of corruption. There should be an obligatory training for the commercial vehicle drivers. Public infringing should be circumvented on the roads, there is need to accentuate the pedestrian crossings. Traffic police need not only check the vehicles but also pedestrian traffic. They should thwart people from crossing roads at high traffic zones. Fine should be levied on the pedestrians who are not using zebra crossings and foot paths provided they exist. Training is a vital contrivance and instructors need to be trained first who should be taught how to train.
It is highly advocated to instil the skills and awareness in the schools and colleges also. It is noticed that the tippers, tata mobiles and other commercial vehicles are driven by minors who do not have any inkling what gaffes they can do on the roads. Rash driving and racing between the commercial vehicles are the causes of accidents. The traffic authorities only know how to do challans, they only punish the drivers who are possessing incomplete documents. They do not prevent the drivers from pledging mistakes on the roads. How many drivers have been penalized for rash driving? Another cause of accidents in Srinagar is teenage bike riders, who are endangering their lives for the sake of stunts that they perform in the cold weather imitating aerobatics. Bikes should have been proscribed in winters in Srinagar a long back, at least for the months of December and January. Another hazard is overloading in commercial vehicles. This has been going on for decades and no one is taking a heed. We have seen passengers boarding and getting down from the commercial vehicles in the middle of the roads. Accidents happen due to the indiscipline created by the commercial vehicle drivers. These drivers know the traffic rules but deliberately break them. In such cases impounding of driver licence for 15 days or 20 days is recommended. The monetary penalty need to be revoked as it only increases corruption. There need to be some firm guidelines for acquiring commercial licence.
The number of vehicles plying on the Srinagar roads has increased to manifold but the roads are the same. So there is a necessity of splaying all the city roads. Foreshortening the density of traffic through hectic plugs is need of the hour, specifically during peak hours. Increasing the number of flyovers and subways will also make the proper traffic flow on the roads. We need to increase the infrastructure facilities for smooth flow of traffic. The train connectivity like metro train should be introduced in the city. One ways should be made the norm throughout. Waterways should be used to conveyance and transport of the goods wherever possible. Traffic police should be deployed at schools and colleges during the peak hours. The commercial drivers need to be educated about their negligence. Shifting of education institutes and government offices to the suburbs is a virtuous alternative.

Hello,
I am Yvon françois TSOLEFACK engineer in electrical and energy engineering of Cameroonian nationality, and promoter of a positive energy road project for Africa, and more particularly in Burkina Faso (pilot country for the experimentation of the project), project which has earned me to won a few brawls and rewards at the end of certain national and international challenges and innovation competitions in energy. I had to consult (carry out a bibliographic review) several works already carried out in the field, via certain open research thesis platforms, which were very interesting. A great thank to all researchers amongs all of you in the field who kindly accept to share their work with me. However, I would also like to do a thesis in co-supervision between the doctoral school of the 2iE institute in Ouagadougou in Burkina Faso, and a suitable school / university which has the expertise in the experimentation of positive energy road technologies. My project (my desired theme) consists of designing a thermo-piezoelectric block capable of simultaneously exploiting the mechanical stresses of road traffic, and the heat stored by the roadways, to produce electricity. It will therefore be a question of carrying out modeling and simulation work in order to determine the optimal structure of the block according to road traffic, vehicle weight, sunshine (temperature profile, humidity, etc.), depending on the context, etc. In short, I would like to have advice from you (the researchers community) regarding the best adapted and advanced doctoral school laboratories in these positive energy road technologies, through which I could carry out my research, in collaboration with the doctoral school of the 2iE institute in Ouagadougou.
While waiting for a favorable result from you, please receive my sincere admirations and considerations.

Dear Dr. Yang Ying ,
I suggest you to have a look at the following, interesting reference:
- Reducing Traffic Congestion and Pollution in Urban Areas
Modern, sophisticated initiatives that are better than typical ‘big ideas’ include:
  • Optimise traffic-light management
  • Use CCTV to monitor road conditions
  • Enforce existing road traffic laws
  • Improve perceptions of buses
  • Extend residents’ parking zones
  • Charge for workplace parking
  • Improve cycling infrastructure
  • Improve bus services
  • Develop and refine park-and-ride
  • Use Inbound Flow Control
  • Rationalise distribution and deliveries
  • Existing rail network
  • Light rail
  • Strategic Road Network resilience
  • Road pricing
It is often incorrectly suggested that congestion may be solved with one big idea, such as:
  • Widen roads
  • Narrow roads
  • Add bus lanes
  • Remove bus lanes
  • Build tunnels
  • Build a new ring road
  • Build a light rail network
  • Switch off traffic lights
  • Ban cycling
  • Ban cars from city centres
  • Close through-routes to private vehicles
  • Close car parks
  • Build more car parks
  • Build more park-and-rides
  • Make buses free
  • Make park-and-ride free
  • Introduce a congestion charge/road pricing

Currently, in my country, tachographs are installed only on vehicles carrying out international traffic (AETR agreement). When transporting inside the country, no devices are used to monitor the work time of drivers. Tell me, where I can see publications on the assessment of accidents before and after the introduction of tachographs (or other control devices) for transportation inside the country? Where can I see the methodology for proving the need to introduce tachographs? any information on this topic?
Relevant answer
Answer
A tachograph is a device fitted to a vehicle that automatically records its speed and distance, together with the driver's activity selected from a choice of modes. The drive mode is activated automatically when the vehicle is in motion, and modern tachograph heads usually default to the other work mode upon coming to rest. The rest and availability modes can be manually selected by the driver whilst stationary.

phases.append(traci.trafficlight.Phase(3, "yyyrrrrryyyrrrrr", 0, 0))
phases.append(traci.trafficlight.Phase(30, "rrrrGGgrrrrrGGgr", 0, 0))
phases.append(traci.trafficlight.Phase(3, "rrrryyyrrrrryyyr", 0, 0))
logic = traci.trafficlight.Logic("0", 0, 0, phases)
traci.trafficlight.setCompleteRedYellowGreenDefinition('B1', logic)
Note: the traffic light ID is 'B1', and I wanted to change the duration of phases 1 and 3 into 30 (initially they were 42).
After printing the new light program, the durations were updated!
