Traffic - Science topic
Traffic is the flux or passage of motorized vehicles, unmotorized vehicles, and pedestrians on roads; or the commercial transport and exchange of goods; or the movement of passengers or people.
Questions related to Traffic
I am a recent civil engineering graduate from Tribhuwan University, Nepal. I have my final year project on transportation engineering. Can anyone, please help me in publishing? The research is about traffic modeling in Pokhara. We are novices in the research area, we need guidance to publish. If you are a professor or can refer someone, please help us.
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?
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?
I want to know about the operation mechanism of SCATS (Sydney Coordinated Adaptive Traffic System), in detail. Can you help me, pls?
I am looking for tools/software to create an online calculator where the user can input parameters. See this as an example (https://lodecrey.shinyapps.io/MS2inactivation)
Shiny app provides these features but the free plan allows quite limited traffic.
Do you have any other suggestion?
Below is my intended objective using B&R automation studio.
（1）After system start-up, the initial status is ：north-south direction red,east-west
（ 2） A certain direction red light holds for 30s,and another direction green light only for
25s.When the green light times out, the yellow light is on for 5s,and then two of the direction’s light exchange, repeats itself ；
（3）When emergency condition, the sequence chart is t0, No matter the status of the traffic light, forced green light to the direction of the Vehicles ,the other is then red ；
（4）When emergency released, the sequence chart is t1,forced yellow light 5s to the direction of the Vehicles（t1～t1＋5）,and then change to red light. After that, Traffic light Controlled is normal
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:-
- I checked the tomtom previous rush hours profiles (2021, 2020 and 2019) for Budapest, which suggests the overall city rush hour to occur on Monday between 7:00 to 8:00A.M.; however, this may not be the reality in the particular route I’m considering in 2022. Therefore, I checked the Traffic Stats function of the TomTom Portal, which offers very limited dates in 2021 for the trial version and information on the speed profile couldn’t help in identifying the rush hour in the route. Therefore, please kindly share your thoughts in identifying the rush hour a selected route?
- Aside from the traditional approach, if you can suggest any other reliable method on the subject, that would be greatly appreciated.
Thanks in advance!
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!!!

I wanted to know how states in US manage their traffic signal hardware - there maintaninance schedule, standards?
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.
Hello. I am a student of "Business Administration" , and i want to do my research on how we can control, manage and ensure discipline in the roads of Bangladesh. As we can see that even after having certain rules and laws, passengers & drivers don't have any respect for the traffic system, which results in various major and minor accidents.
As it's and important issue in our country, I will be researching the root causes of this problem, and talk about what needs to be done.
I would appreciate your thoughts and ideas about this topic. Thank you.
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?
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.

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.
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.

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.
I am interested in how to ensure the maintenance of high transport quality of roads during the period of heavy traffic.
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.
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?
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?
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?
I'm doing a safety study on Malaysian Expressways (E1, E2, & E8) so, I need traffic volume data of the North-South Expressway (E1, E2) and East Coast Expressway (E8) includes, Annual Average Daily Traffic (AADT) and Average Daily Traffic (AADT) of heavy vehicles for at least one year such as 2016, 2017, or 2018.
Please help me with this thank you All.
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!
How much time is necessary between successive vehicles in a traffic stream at a signalized intersection?
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.
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 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:

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.
I'm doing research in Intelligent Transportation Systems (ITS). Currently, we are studying the traffic status, trying to detect any traffic congestion using AI-based solutions. I have used synthetic data (generated by Simulation of Urban MObility) in order to validate our proposed algorithm. However, we are also interested to validate our algorithm in a real-world environment. Can you help me to find a free source for traffic real-dataset?
The data I need should contain:
- Speed, flow, or occupancy parameters on a particular road.
- Labels for the traffic jams (if it's happened), with the starting time of the jam.
Your help is much appreciated, Thanks in advance.
We want to look at the association of having been in a road accident (as a driver) by a variety of parameters.
Most of the research articles are compared and tableted the different methods and metric values when come for result & discussion. Are they really taking the result of each method before the mention in article.
Im looking for doing work on Multi scale -CNN model for Traffic Sign detection and recognition. I expecting your valuable suggestion and input for my further movement.

Its development contemplates the coverage of Magical Towns like Artega, Coahuila.
The Poisson's ratio of soil is quite difficult for us geo-engineers to obtain. I came across a problem when I tried to determine the parameters in a FEM model.
For the saturated clay in undrained condition, the poisson's ratio is seen as 0.45-0.50. But when analysising the field vibration induced by traffic transmit, the soil is simplified as a linear elastic body. So we could calculate it with K0, which is usually given in the investigation report. The calculating result is usually smaller than 0.45.
I think different poisson's ratio would have an impact on the strains in lateral directions. Was there any person knowing the effect or studying on this? Thanks a lot.

I am trying to study the network traffic detection, and someone suggests me to choose CTU-13 dataset as ML model training and testing dataset. I have downloaded the CTU-13 pcap files, but I do not know how to check their packets label. The label file is named apture20110XXX.pcap.netflow.labeled file, I cannot open it. Someone can help me to figure out this problem. Thanks!
Hello everyone, hope you are doing well. I made a simple traffic actuated control logic using VisVAP and it's working fine. now I wanted to add function such when vehicle is detected the pedestrian signal shall turn to green flashing and after 10 seconds, pedestrian stage shall change to vehicular stage. There is function that can set pedestrian signal to green flashing but logic is not changing to stage transition after green start flashing or sometimes even skip green flashing and change to vehicular stage.
Stage 1 is for Vehicle
Stage 2 is for Ped
Any help in this regard will be appreciated. Thank you. Picture of the logic and .vv file is attached.
Thank you very much

I would like to ask if there are some open and customisable platforms dedicated for railway systems (in particular for traffic management: like SUMO for automotive)
If the answer is yes, what is the best plateform?
Recently I started studying some research articles related to road traffic congestion control, but not able to understand the objectives correctly. I am requesting to provide some guidance and give some inputs for better understanding and to identify the existing research gaps.
I need a simulator for generating data traffic (the time, location, speed of the agents on a map) with the following requirement:
1-It should be agent-based.
2- I want to generate random networks with different traffic lights and roundabouts.
3- I should be able to import open road/street maps and then adding some traffic lights, and any other objects to the maps.
4- Graphic is not important to me and my aim is just to generate traffic datasets.
I want to make all the mentioned requirements as automatically as possible to generate thousands of different scenarios.
Given the parameters CC0 to CC9, are driving behaviors (i.e. ABX, SDXv, CLDV, etc.) assigned from random distributions surrounding the input values of those parameters? Or are the behaviors directly derived from the parameters with no random variation between drivers? I'd hope VISSIM would do the former, but I'm new to this and don't fully understand much. I do know that desired speed and max/min accelerations are randomly assigned, but those aren't based on "parameters" in the same way that min. follow distance and speed oscillations are. I did read the original Wiedemann (1974) notes, and his original model clearly assigns driving behaviors randomly, but it isn't so clear for the modern VISSIM implementations. Any help would be appreciated!
