TLDR
This paper deals with two formal approaches based on Petri nets for a single crossroad that make it possible to study the traffic behavior at crossroad in a microscopic point of view and in a macroscopic one.Abstract:
Minimizing the queue length and vehicle delay time at crossroads is a major problem in the regulation of the traffic urban networks This paper deals with two formal approaches based on Petri nets for a single crossroad On one hand, these approaches make it possible to study the traffic behavior at crossroad in a microscopic point of view and in a macroscopic one On other hand, the developed models provide a tool for the performance analysis of the different traffic signal's control For this purpose, we show the performance indices of the vehicle interval control, which are obtained from simulation examplesread more

Modular Design of Urban Traffic-Light Control Systems Based on Synchronized Timed Petri Nets
TL;DR: A new methodology to design and analyze an urban traffic network control system by using the synchronized TPN (STPN), and the applications of the STPN to eight-phase, six- phase, and two-phase traffic-light control systems are modularized.

Design of Traffic Safety Control Systems for Emergency Vehicle Preemption Using Timed Petri Nets
TL;DR: This is the first work that employs TPNs to model an emergency vehicle preemption system and identify its urgent spectacles for the purpose of their complete avoidance and helps advance the state-of-the-art in traffic safety related to the intersection of roadways.

Critical Scenarios and Their Identification in Parallel Railroad Level Crossing Traffic Control Systems
TL;DR: This is the first work that employs DSPNs to model a parallel railroad LC system and identify its critical scenarios for the purpose of their complete avoidance, and helps advance the state of the art in traffic safety related to the intersection of railroads and roadways.

Design of Traffic Light Control Systems Using Statecharts
TL;DR: This is the first work that employs statecharts to obtain the models of the urban traffic light control system and proposes a new modeling methodology, called concurrent state graphs, that allows us to present all the concurrent states in complex state charts.

On kinetic waves, II . A theory of traffic flow on long crowded roads
M J Lighthill,G B Whitham +1 more
TL;DR: In this paper, a functional relationship between flow and concentration for traffic on crowded arterial roads has been postulated for some time, and has experimental backing, from which a theory of the propagation of changes in traffic distribution along these roads may be deduced.

On kinematic waves II. A theory of traffic flow on long crowded roads
TL;DR: The theory of kinematic waves is applied to the problem of estimating how a ‘hump’, or region of increased concentration, will move along a crowded main road, and is applicable principally to traffic behaviour over a long stretch of road.
Journal ArticleDOI
Shock Waves on the Highway
TL;DR: In this article, a simple theory of traffic flow is developed by replacing individual vehicles with a continuous fluid density and applying an empirical relation between speed and density, which is a simple graph-shearing process for following the development of traffic waves.
Traffic signal settings
TL;DR: In this article, the authors present an approach to evaluate the number of delays at a signal-to-interception intersection and propose a formulae to calculate the average delay per vehicle.

Particle hopping models and traffic flow theory
TL;DR: This paper shows connections between fluid-dynamical traffic flow models, which derive from the Navier-Stokes-equation, and particle hopping models, and starts building a foundation of a comprehensive dynamic traffic theory, where strengths and weaknesses of different models can be compared, and thus allowing to systematically choose the appropriate model for a given question.
