Traffic - Science topic

Could you please provide me the web sources, (i.e., paid or free) to download "Average Annual Daily Traffic Volume" or "Daily Traffic Volume" Data?

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:

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.

I am trying to build random parameters model with heterogeneity in mean and variance (RPNB-HMV) models for road traffic crashes on a highway in India.

Random parameter Negative Binomial models are the most popular models for assessing unobserved heterogeneity in crash prediction models.

I want to know some free or open-source software like R for fitting such models.

E.g. A sample syntax of the RPNB-HMV model in R software.

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.

My friend: Thanks a lot. You made it clear.

Me: You are most welcomed.

Please press the like and share buttons to clear it for everyone.

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:

(For specifics on my current survey, it's a bunch of Likert scale questions aimed at getting opinions about bilingual signage in a small town. I'm standing in front of grocery stores to encounter people as there really aren't any other places with regular foot traffic.)

Snow accumulation on road surfaces will turn into ice by over-passing traffic, especially heavy traffic. Ice will move by a small amount every time a vehicle passes. Why will it end up in pointed, thorn-like peaks?

In an experiment to compare several Queueing Disciplines with respect to Quality of Service metrics QoS using Opnet14.5 simulator, I keep getting high rate of dropped traffic!!

These high rates are unjustifiable to me, as results of the experiment show the received traffic is only slightly less or in some cases almost the same as the sent traffic!!!

Anyone may have an explaination please?

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?

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).

I am looking for hourly interval data of traffic of Pasadena California

I need traffic data such as shown below.

•Traffic Composition.

•Traffic classification.

•Vehicles classifications (Light Vehicles- Heavy Vehicles-Motorcycles).

•Average Speed.

•Acceleration and deceleration.

•Traffic Density (vehicle/kilometre).

•Volume (vehicle/hour).

•Speed classification.

•Speed categories (Min.-Max.)

And the geometric data of the highway.

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.

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?

Can anyone suggest a good PhD topic in traffic particularly in pedestrian crashes

e.g., traffic volume versus crashes per year (other than using simple correlation)

Would like to research the entire connections per airport on the globe, not the single flights such as in flighttraffic. Is there an updated map available somewhere.

Surrogate Safety Measures (SSM) are used to measure traffic safety. Some video-based software can generate these values from real vehicle traffic videos. So, is there any device that can be mounted on a vehicle, is portable and can measure all/some of the SSM metrics?

We use ECM to predict Dutch yearly traffic kilometers. For year 2020, the covid-policies impact the traffic performance a lot. We need to use data from 1983-2020 to obtain coefficients of independent variables, such as GDP, population, oil price...to estimate traffic kilometers for year 2021 to 2025. Therefore we add a dummy variable to present the covid-policies for year 2020. The question is: should the dummy for both short and long terms or only for short term?

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?

What are your wiews regarding the statement " The global shrinkage of distances via Air/Ground/Sea traffic over the applications of  IT/AI increased the access of humanic miseries very common for everyone on the globe".

To me, these (e.g., COVID-19, Some WARS...) are mostly due to the impacts of information technology and artificial technology applications.

Descriptive research such as research describing a large dataset such as a travel behaviour dataset via preliminary analysis.

I am trying to build a mobility module using SUMO for my VANET work and I don't fully understand the following terms.

Are Traffic Density (Vehicle/Km) and Traffic Flow (vehicle/km/hour) values only valid for a single 1Km lane and when there is a multiple lane 1Km road, it must be multiplied by the total number of lanes in the 1Km road?

For example, if I selected the Traffic Density to be 40 vehicles/km and I have a 1Km two-way road with 3 lanes on each side, the actual Traffic Density will 40*6 vehicle/km?

Closed Parkings and tunnels;

Many parkings are closed and a lot of them are located in Airports; sadly people have suffocated in them due to traffic jams and congestion; would replacing fuel transport with EVs solve problems caused by pollution fuel transport causes?

Dear All,

I’m planning to conduct a traffic count in the coming days for selected route near my university in Budapest. Currently, I'm attempting to identify the rush hour time along the route. Accordingly, I'm trying to use an approach based on real time information other than the traditional method. Underneath, please see the steps I took so far and kindly share your helpful thoughts:-

Thanks in advance!

Hello everybody,

I was going to develop a reinforcement learning algorithm for railway traffic rescheduling. For the evaluation purposes I am going to use some simulators like OpenTrack. But I am really not sure now that it is possible or not to evaluate my model using OpenTrack. If anyone has experience on it could you share your opinions about it.

What kind of railway traffic simulators would you recommend to evaluate reinforcement learning algorithms?

Thank you in advance!!!

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)

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?

Hello everyone,

I am searching for a road network dataset and its corresponded traffic data. I have found some road network dataset in the web, however, no traffic data has been attached to it. Therefore, I would be grateful if anyone could help me in finding such data.

Thank you in advance.

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.

To study the impact of public transport on traffic safety on urban road networks and traffic at bus stops

In 21st century Artificial Intelligence and IoT based traffic systems are being researched across the world. But implementation rate and the economical efficiency are yet to focus on.

I want to know if there's any algorithm or standardised system confirmed for future research to deploy a universal traffic management system. Human intervention in traffic system and algorithm based traffic controlling should be alined for further development to ease current traffic issues.

Such a system can mean less volume of cars in large cities, which can free up parking spaces and facilitate traffic.

I want to measure the number of customers who come to a store at different intervals

Can you help me?

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.

Best regards,

Yvon François TSOLEFACK

the traffic light sometimes is easier to cause the traffic jam problem, if the designer don't make to many change to the both side of the road,such as the house and block building, what other aspect of things can be done to mitigate the traffic jam problem.

Hello, is there any resource containing vehicular Traffic data (flow, speed ..) in any street or highway in Morocco?

I want to simulate one traffic intersection.

Dear fellow researchers,

I would be thankful if you can provide me with some of the main references in the existing literature about the societal value of traffic information to train passengers in case of service disruptions.

I would also be interested in related literature such as studies on train passengers' behavioural changes, methods to assess the benefits of traffic information.

Dear Sir/Madam,

I want to estimate the incoming and outgoing traffic volume of a ward area. There are many roads stretches passing through the ward. Can you suggest some way or any effective paper as a reference to count the incoming and outgoing traffic volume for that ward?

Thanking you.

I have a 5-year combined crash data (2013-2017). What representative traffic volume data should I use for crash frequency modeling?

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?

Dear researchers,

I want to apply clustering tasks for city traffic time series for a research in Intelligent Transportation Systems.

Can you recommend a city traffic dataset that contains the speed, flow, or occupancy measurements for roads and also contains the type of traffic pattern for each road? This type can be provided as a class label for each road, or a class label for each day measurements on each road (a class label for the whole time series).

Any help is much appreciated, thanks in advance.

In IDS, the researcher converts raw traffic (PCAP) to CSV format. Character-level CNN is specialized in character text classification, so I would like to ask whether CLCNN can be applied to IDS?

Hello Dears,

Based on simulation, modelling, and traffic data

By collecting traffic flows data in the first 300s in SUMO, I calculated the optimized green time by an algorithm in python and now I want to change the duration of phase in next 300s.But in the documention I did not find useful funtions, so how to achieve this step to complete the real-time control for the traffic lights? Thanks a lot!

Any suggestions or ideas you think this can be achieved?

How much time is necessary between successive vehicles in a traffic stream at a signalized intersection?

Are there any studies done regarding this phenomenon?

Hello everyone

I just want to know the traffic volume entered in the VISSIM is whether average or maximum or 30th highest hourly traffic volume of the stream.

Thank you in advance.

Can SDN control certain types of traffic to be sent first, and certain types of traffic to be sent later?

Hi,

I have to simulate and model the two traffic classes, particularly video traffic and the alarm message, where high priority is been given to the alarm message over the video traffic.

Can the arrival rate of video traffic be considered as a Poisson process?

If the arrival rate of video traffic is not Poisson, then M/G/1 queue model cannot be applied.

In that cast which queuing model will be appropriate?

How am I suppose to proceed with this problem in MATLAB?

Where can I find some public pcap traces of data centers running applications like spark or hadoop? Or Is there a way to emulate the traffic in such a cluster running through the switch?

I'm doing QoS in Manet using Priority AODV. I need classification algorithm to handle the real and non-real time packets. For priority scheduling, I want to use WRR scheduling mechanism so that the classified packets mapped into queue in a way real-time traffic hold high priority than non-real time traffic. For admission control, I want to estimate the available bandwidth. Incoming flows rejected for transmission if threshold less than amount of flows.

The objective is to estimate the effects of illegal parking (double-parking) on traffic conditions

The implementation of the literature methods is not trivial. After many attempts, I'm looking for a published code to improve my own code.

I refer to measuring methods like those mentioned in:

SDN sends the specified traffic data.

For example, it first classifies the traffic and then sends the specified traffic (such as a download or video stream).

I am trying to solve the Wi-Fi offloading decision making problem using classification and clustering of known and unknown traffic respectively in a given mobile network using bi-flows of packets in the network

I am doing a research on Truck Traffic congestion at Maydon Wharf Terminal

We are designing a system that is named as "GPS based traffic monitoring system", that will be helpful in reducing accidents, data collection, traffic congestion avoidance and a lot more. could you please assist me in doing so?

Initiated actions - Train traffic, Drilling, Tunneling, Excavations, Construction (underground), Extraction of minerals, etc.

Note: The answer may also consider upper or on the ground initiated actions as well.

I am working on an air pollution model for which I require traffic volume data for Delhi region for the time period 2011-2020. Kindly advice from where I can get that?

According to the nature of temporal data, strategies like k-fold cross validation is not an appropriate idea since we cannot remove the dimension of time. In this discussion we want to explore ideas about testing models for temporal data.
