Abstract This survey paper presents the various urban traffic control strategies which have been proposed or applied to prevent and treat congestion. Some basic definitions about congestion, such as primary and secondary congestion, are remembered. Freeway control during congested situations is examined; the access control and exits control problems ...

ACM SIGMETRICS Performance Evaluation Review, 2014
We develop two models of highway traffic: (i) a deterministic fluid model based on conservation laws building on previous work and (ii) a mean-field model of a series of infinite server queues, where each stage in the tandem models a segment of highway.

Traffic Congestion Identification and Reduction
Wireless Personal Communications, 2020Historical data is increasingly becoming more purposeful in the field of intelligent traffic systems. Traffic congestion is one of the major challenges in most cities around the world. It increases fuel wastage, monetary losses, and life-endangering. Historical trajectory data may be a suitable solution to reduce congestion on the road in VANET.

Congestion control for UDP traffic
Proceedings of the Fourth IEEE International Symposium on Signal Processing and Information Technology, 2004., 2005Development of network-sensing and congestion-control mechanisms is one of the focus topic in the modern society of information as consequence of the huge growth in types of services, data links and connectivity. A monitoring system based on hidden Markov model is proposed and implemented such to interact with distributed Internet generator ...

Analysis on traffic congestion propagation influenced by traffic congestion information
2011 International Conference on Electric Technology and Civil Engineering (ICETCE), 2011The effectiveness of traveler information is increasing and information plays an important role on the improvement of the status of urban transportation network jams. In this paper, the mathematical model was formulated to describe the effectiveness of traffic jams information under the assumption of simple network and linear cost function.

Traffic Congestion Control of Traffic Network
IFAC Proceedings Volumes, 1992Abstract This paper studies the traffic congestion control of a traffic network from the system-theoretic viewpoint. The feedback control of the traffic congestion length is considered at each signalized intersection in a traffic network. Then we propose two systematic control algorithms for traffic congestion length control in a traffic network ...

Relaxation dynamics in congested traffic
Physical Review E, 2005We investigate the relaxation dynamics in congested traffic when starting from the "megajam" initial condition (all cars standing in one big cluster of density 1) in the framework of the traffic model proposed by Nagel and Schreckenberg. On the one hand, a simple comparison of the time evolutions of some relevant traffic quantities shows that the ...

Traffic congestion is associated with enormous time, fuel, environmental, and health costs. As traffic congestion worsens around the world, it is becoming increasingly crucial to understand how congestion policies affect mobility and the economy. In the first chapter, I present stylized facts about traffic congestion. I document the extent to which

Forecasting of Traffic Congestion
2000Results of investigations of a recent method for the automatic tracing of moving traffic jams and of the prediction of time-dependent vehicle trip times are presented using different levels of data inputs. The method is based on the previous findings that moving jams possess some characteristic parameters, i e., the parameters are unique, coherent ...

Traffic congestion catastrophes
Transportation Planning and Technology, 1986Authorities in both traffic engineering and driver behaviour have empirical evidence that drivers' behaviour differs when journeying in free moving traffic or stop and go situations. Catastrophe theory provides a unified approach to explain the sudden change in traffic stream behaviour.
