Urban Traffic Control is a key problem for most big cities. An inefficient traffic control system can lead to increased traffic congestions that degrade city quality metrics such as average travel time or city pollution. Most common approaches focus on controlling traffic by appropriately setting traffic lights. Current systems in operation range from static control of traffic light phases to a...

Urban-scale traffic monitoring plays a vital role in reducing traffic congestion. Owing to its low cost and wide coverage, floating car data (FCD) serves as a novel approach to collecting traffic data. However, sparse probe data represents the vast majority of the data available on arterial roads in most urban environments. In order to overcome the problem of data sparseness, this paper propose...

The problem with traffic congestion is particularly expressed in urban areas where possibilities for physical increment of capacity are limited or impossible. Significant in the approach to solving this problem is the usage of Public Transport (PT) and the implementation of various advanced control measures that can improve the quality of overall public transport system. The main objective of t...

Rapid and concentrated growth in many urban areas has led to a dramatic increase in the number of commuters and a subsequent strain on many cities’ traffic signal facilities. Although traffic delays have almost become an accepted part of our culture, significant efforts (and funding) are focussed on improving the overall performance of urban traffic-control systems. Unfortunately, responses to ...

Short-term prediction of traffic flow is central to alleviating congestion and controlling the negative impacts of environmental pollution resulting from vehicle emissions on both inter- and intra-urban highways. The strong need to monitor and control congestion time and costs for metropolis in developing countries has therefore motivated the current study. This paper establishes the applicatio...

The Highway Capacity Manual (HCM, 1985) has defined level of service mostly for the developed countries having predominant contribution of motorized vehicles. There are very fewer number of models to simulate the urban heterogeneous traffic flow having significant proportion of non-motorized vehicles. These types of flows are mostly observed in the countries of Asia-Pacific region. The flow of ...

Background and aims: This study aimed to evaluate the effect of enforcement of new traffic laws on the fatal and non- fatal injury rates in Iran. Methods: In a longitudinal, interventional controlled trial study, all subjects with history of fatal and non-fatal injuries were studied. Their injuries were caused by six risky violations (unauthorized speed, illegal overtaking, red traffic light c...
