This paper deals with modelling of traffic networks for control purposes. A modular framework based on coloured timed Petri nets is proposed to model the dynamics of signalized traffic network systems: places represent link cells and crossing sections, tokens are vehicles and token colours represent the routing of the corresponding vehicle. In addition, ordinary timed Petri nets model the signa...

We studied all traffic accidents to pedestrians under age 15 which occurred on the Island of Montreal during an eighteen months period. Data were collected from eleven hospitals and completed with accident police records. A spatial quadrat analysis, a Comparative Accident Index, and a comparative analysis of the means of different socio-ecological variables between high and low risk accident ar...

A traffic light is a device for the regulation of traffic between road users, vehicles and pedestrians. The setting and synchronization of traffic lights of an axis or an area are very complex, and sometimes unsatisfactory for all or part of them. In addition, according to several studies, traffic lights would be responsible for half of the traffic jams and thus half the pollution, and poorly r...

In this paper, we consider a simple road intersection with traffic light control and suggest queueing model for the flow in intersection. The suggested implements well-known queue state-dependent departure rates. Using model, define optimal scheduling of lights its properties. Activity is illustrated by numerical simulations. It demonstrated that practical conditions allows prevention jams reso...

The green and red lights of a traffic signal can be viewed as the up and down states of an Ising spin. Moreover, traffic signals in a city interact with each other, if they are controlled in a decentralised way. In this paper, a simple model of such interacting signals on a finite-size two-dimensional lattice is shown to have Ising-like dynamics that undergoes a ferromagnetic phase transition. ...

This paper presents a method of adaptive traffic signal control using time series forecasting and real time signal phase adjustment. The situation in which a green light turns red before passing an intersection is a familiar and frustrating experience to drivers. The proposed forecast based traffic signal adjustment attempts to predict and alleviate this situation by extending green lights in r...

Traffic management is the critical issue of the road. Traffic lights play an important role in the traffic management. The existing traffic lights follow the predetermined sequence. So these lights are called static traffic lights. These traffic lights are not capable to count the number of vehicles and the priority of the vehicles on intersection point. As a result some vehicles have to wait e...

nowadays, the use of intelligent control systems to reduce human error is one of the most popularresearch fields. design and implementation of such controllers requires to actual knowledge of theenvironment conditions. traffic lights as one of the inputs of intelligent control systems are significant.usually the traffic lights have the various physical structure. also, generally in image proces...

We apply the genetic algorithm technology in the traffic control system and pedestrian crossing to provide intelligent green interval responses based on dynamic traffic load inputs, thereby overcoming the inefficiencies of the conventional traffic controllers. We apply such technology to a four-way, two-lane junction based on two sets of parameters: vehicles and pedestrians queues behind a red ...
