Questions related to Transport Planning
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 would be grateful if anybody could point me to published research discussing the role of public administrations in freight transport planning/policy and what data they collect and use to base their policy upon, especially if such data is from real-time systems (perhaps once summarised). Please note that my interest is for intercity freight transport particularly.
Very many thanks!
Dear All, within our new European project SYN+AIR related with the air transport we are executing an online survey which aims at identifing the mobility choices related to and from the airport. We are glad to invite you fill in the survey https://ec.europa.eu/eusurvey/runner/SYN_AIR_Traveller_Survey_2021 The questionnaire is available in 5 languages (English, Greek, Spanish, Italian, Serbian) and lasts approximately 10 minutes. All adults that travel or used to travel by plane (before the Covid-19 pandemics) can answer this survey. You may find information related to the project at http://syn-air.eu/
Please, feel free to share/disseminate this request. Thanks a lot for your attention and contribution. #SESAR #H2020 #SYN+AIR
Dear colleagues in different fields of transport planning. I am currently conducting a study called "An integrated study of Park and Ride (P&R) facilities for sustainable urban mobility," which involves research and evaluation of the P&R system components in a mid-sized Latin American city. I have already researched the following: Land use, location of facilities, starting points for travel generation, catchment area, P&R demand, P&R capacity, dynamic accessibility, environment, interaction between (conventional, autonomous, electric vehicles with the P&R system)
I would like to know your opinion as transport planners, which other components should be taken into consideration. Thank you in advance for your feedback.
Different transportation, land-use, environmental, and other corresponding planners propose their work for new city urban plans in order to address the existing problems by identifying the major gaps they had. The existing land-use was following bad planning principles and it is already a failed plan. When planners integrate their proposed spatial plan to existing land use, they will have a real challenge in aligning. So, as a planner, what would be your choice to align the proposal you have with the existing land-use?
- Shall i follow the standard plan i have and remove the existing unplanned land-uses( NB: the compensation cost may be too large) ? or
- Shall i accept the existing situation as it is and compromise the planning standards?
What is your suggestion?
Any help is appreciated very much.
Different transportation planners use different criteria to suggest or to propose a public bus route for one city.
There are different considerable factors to be used as a reference to propose such projects such as Traffic volume, future population dynamics, decision-maker's point of view, land use characteristics and other demographic characteristics may be used as a reference to propose a public bus route system for one Metropolitan city.
And, To consider the whole things in one case, it needs special, long preliminary investigations and careful attention.
I know that there are a bunch of planning concepts from different literature, But, i need a clear image on what were the necessary and obligatory planning criteria that must be considered in proposing public bus routes for one developing countries?
Any help is appreciated. It is open for learning-teaching discussion.
An interesting and important matter in relation to the Australian society (its struggle to handle high population growth) put forth in a compelling manner. Another example highlighting the lack of systems thinking on the part of decision makers. It shouldn’t be narrowly focused everything is the economy only perspective. There is a whole system out there. High migration rate keeps the economic figures in a good shape. But infrastructure building must be on par with the population growth – better transport plans and infrastructure, more school and hospitals. Otherwise, the overall productivity of operation will continue to decline and causing major economic and other problems in the longer run.
The domain of my research will focus on aviation security and transportation security officers; thus, I realize any available measurement tools may need to be adapted/customized
I want to establish the relationship between the accident rate m such features as gross domestic product, the auto industry, the number of inhabitants, the density of the road network, etc.
What are the sequenced steps of urban transportation planning process?
The question refers to workload management from different perspectives: organisational, individual, operational demand. I'm just interesting in different viewpoints on this question
I am looking for the effect of hot climate on the behavior of transit use and public transportation ridership? and what is the human thermal comfort in outdoor spaces in a hot arid region?
I am working on Vehicular Networks and on a problem that is concerned with the %age of public buses in metropolitan cities.
What would be the safe assumption to make as to what is the percentage of public buses of the total vehicular density in urban scenarios? Somewhere I read that public buses would be 25 to 30% of the total vehicular density in the urban scenarios, but I cannot find the reference.
Any resource and/or reference would be highly appreciated.
I want to understand how the initalisation of algorithm in the attached file have to be ?
What the autor means by the active direction ?
How did he fill the matrix of red and green period .
Thanks for response in advance.
I am working on a research to look at the question of demand for BRT and how it is shaped by the urban environment (densities along the corridor, population characteristics, employment characteristics, etc.)
I am interested in applying UNA to Colombo. But still I could not find the exact way of doing it. The available tutorials in the internet only explain the GIS steps in applying it. I am worried on preparation on the weighted attribute table. So if anyone can help me in finalising the required database for the UNA will help me a lot
I am interested to learn and "play" with a group of students a "serious games" related to urban and transport planning. It would be very useful therefore to know some available examples and already usable to didactic purpose.
i wanna do research about mesoscopic traffic flow parameters which affect crash severity in urban highway. i know that mesoscopic parameters are combination of macroscopic & microscopic parameters. but what kinds of variable should i consider for making a crash severity models
thanks for your time and consideration
The planners design a tramway for a road with around 4000 passengers/hr per each direction in peak hours . Just I want to examine the possibility of implementation of BRT mode instead of Tramway.
I have simulated a signalized intersection in VISSIM. For the left turning vehicles, I have provided an exclusive short lane of length of 50 meters at the intersection. The green time of the main lane(for vehicles travelling straight) is 30 seconds out of 70 seconds cycle time. The left turning lane gets an additional 5 seconds of green time above this. Can some please explain how can I calculate the capacity of the left turning lane?

How can the architectural profession provide an environment for increased informal neighbour interactions, especially in high-density developments?
Where and how do you usually make contact with your neighbours?
Are you aware of any great publications or building case studies related to this area of research?
Recently, several studies on calibrating traffic flow models have been undertaken using support vector regression (SVR). For me, the method seems to be a bit counter-intuitive. Rather than the sum of the squared errors, the sum of squared prefactors of the model function is minimized. However, this seems to have nothing to do with the fit quality itself. The fit quality enters only indirectly in form of some constraints, and small deviations are not penalized at all. Furthermore, you obtain a sort of black-box model which is lengthy to write down explicitly and which cannot be understood intuitively. Under which circumstances, the SVR should nevertheless be preferred to an ordinary LSE minimization?
Do you know any cases of congestion charging/pricing schemes in the global South? I have heard that New Delhi has been considering implementing one, and so has Beijing... but apart from several European cities and Singapore (where the idea came from, apparently), are there any other municipalities in Africa, Asia or South America that have played with this idea?
Thanks for your help!
I looking for cities/towns located in the global South (South America, Africa, ... but the list could include also China and India!) which have experimented (or at least considered) the introduction of free (= zero-fare) public transport.
Your help is much appreciated!
I know this is a long shot and it's something difficult to research let alone find on the internet, but if you have any references about this subject I'd be grateful. It's more from a standpoint of traffic psychology. Example:
There are 2 routes and both have similar features as well as distance to the final destination. One of the routes is more important and thus is used heavily by buses. If drivers knew that fact, at what percentage or would they at all (but it has to be proven) choose the other route?
My idea is to develop a 2-dimensional simulation for a real time traffic camera input. I need to create agent objects for each vehicles and pedestrians in real time video captured via camera. I want to recognize the objects with the help of object identification techniques too. Finally my simulator should represent all recognized objects in the video.
Could you recommend any reports, books etc. about the influence of automatic incident detection or incident management on the traffic safety? especially road infrastructure...
India has a huge domain of public transports most of which is decentralized and ill-organized.
Proposed Ubiquitous Transport System would provide a single-window approach to transport facilities where it will be easier for people to avail transport services.
How far is its implementation feasible in the huge and diversified domain of India?
Or is it a good idea bringing all the transport facilities under a single portal?
I would like to know aboutthis area regards research about accessibility and mobility of transportation for people with disability by their daily, weakly, monthly and anualy activity for different trip purpose by different modes, which factor make most of influence of their behaviour in trip demands and is it possible to measure the costs of their trips and do they have influence on making their trips in realtions to subsidies and discounts. Also I want to know more about whether it is possible to measure sustainable transportation for people with disability.
I am interested in examining the traffic safety situation of some cities/ towns in my country. Does anyone have expertise in this field by way of research?Is there any model I should know about? What should I consider in terms of variables?
In downtown and heavy commercial areas, pedestrians use streets and interact/conflict with vehicles. Therefore, causing congestion that is caused by heavy traffic as well as pedestrian conflict. When analyzing/simulating (vehicular) traffic operation using the regular tools (HCM and others) and adding some friction factors to account for pedestrian conflict, results are not reasonable compared to real life conditions.
Does anybody know of a model or a methodology to analyze or simulate the pedestrian-vehicular traffic conditions?
my research starts from many real time data relating to traffic and congestion phenomenon on road network.
i need of specific mathematical approach that define variation of pollution emission through traffic data and enviromental aspect
In developing countries, demand aspects of public transit have received very limited attention as compared to the design and engineering aspects. Further, transport studies conducted in those countries are suffering from virtual lack of a database on urban transport statistics or project based or either very aggregate.
Given circumstances, there is a need on a simplified method to measure transit demand of public transit stops. This study suggested that network centrality measures tool is robust, dynamic planning tool that will offer promise for transport planning applications in Indian context.

I'm currently looking for any research related to improving the use of public bike sharing systems. Having a system installed in the city I'm looking for scientifically proven measures to increase the use of it. Any idea of real research on that topic?
I'm well aware of European projects like OBIS. But any suggestion is appreciated.
I want to model of predictions of passenger flows in traffic based on the theory of uncertainty (rare events). Is there any suggestion for this?
Research shows that centralizing a business structure in a city would lead to major congestion in public transportation system during an increase of population growth.
People are required to travel to the CBD for job opportunities hence, this leads to issues such as inefficiency of public transportation system.
Where I can find a good explanation of the difference between stochastic and deterministic optimization of transportation network design?
There's a growing body of research relating transport infrastructure (particularly transit) to land values, mostly in suburban situations. But how can we identify and quantify the potential benefits of proposed transit facilities to CBDs and the inner city?
Most transit facilities don't stack up in traditional benefit:cost analyses, but may afford great benefits in amenity, livability and the socio-economic wellbeing of our city centres. How can we evaluate those benefits and include them in the benefit:cost equation? Or, if we are stuck with some sort of MCA, what measures are available to allocate scores to such benefits in such a way that they can be weighed against implementation costs?
The same question applies also to active transport infrastructure.
