Analysis on traffic congestion propagation influenced by traffic congestion information

2011 International Conference on Electric Technology and Civil Engineering (ICETCE), 2011
The 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, 1992
Abstract 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 ...

Measuring Traffic Congestion

2015
Congestion in transportation occurs when the occupancy of spaces (roadways, sidewalks, transit lines and terminals) by vehicles or people reaches unacceptable levels of discomfort and delay.

Traffic congestion catastrophes

Transportation Planning and Technology, 1986
Authorities 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.

Relaxation dynamics in congested traffic

Physical Review E, 2005
We 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 alerting system

2016 International Conference on Computing Communication Control and automation (ICCUBEA), 2016
As traffic congestion creates negative impact on society, traffic controlling is the important necessity in transportation. Traffic management requires technology based solutions instead of the manual methods such as human intervention viz. traffic policemen, traffic lights and safety cameras.

Traffic Congestion and Accidents [PDF]

, 2006
Obstructions caused by accidents can trigger or exacerbate traffic congestion. This paper derives the efficient traffic pattern for a rush hour with congestion and accidents and the corresponding road toll. Compared to the model without accidents, where the toll equals external costs imposed on drivers using the road at the same time, a new insight ...

Dynamic traffic control for congested traffic

2014
This study developed a dynamic traffic control formulation designated as Dynamic Intersection Signal Control Optimisation (DISCO). DISCO considers the entire Fundamental Diagram, which is essential for controlling congested and transient traffic. As a dynamic model, DISCO works with time-variant traffic patterns and derives dynamic adaptive timing ...

Traffic congestion and restraint

1974
The motor car is an invention which, within half a century, has revolutionised our way of life. It has made possible a dispersal of dwellings far exceeding that of the railway age, it has offered a wide choice of employment situations and has increased the scope of recreational activities to a remarkable extent.
