TLDR
It is shown that traffic jams can move in a stable manner through a highway, keeping their structure and characteristic parameters for an extended time.Abstract:
Based on experimental investigations of traffic on highways it is shown that traffic jams can move stable through a highway keeping their structure and characteristic parameters for a long time (at least for about 50 min, when the jams moved through the longest, 13.1 km, section of the investigated highways). The experimental features of an almost stationary moving jam have been found. An occurrence of complex space-time structures of traffic inside a wide traffic jam has been observed. \textcopyright{} 1996 The American Physical Society.read more

TL;DR: This article considers the empirical data and then reviews the main approaches to modeling pedestrian and vehicle traffic, including microscopic (particle-based), mesoscopic (gas-kinetic), and macroscopic (fluid-dynamic) models.

The physics of traffic jams
TL;DR: In this paper, a car-following model is proposed to investigate the bunching transition and bus delay in traffic flow and pedestrian flow, and detailed results obtained mainly from the microscopic car following models are presented.

A simplified car-following theory: a lower order model
TL;DR: A very simple “car-following” rule is proposed wherein, if an nth vehicle is following an (n−1)th vehicle on a homogeneous highway, the time-space trajectory of the nth vehicles is essentially the same as the (n −1) fourth vehicle except for a translation in space and in time.

Enhanced intelligent driver model to access the impact of driving strategies on traffic capacity
TL;DR: A new car-following model is proposed that also serves as the basis of an ACC implementation in real cars and eliminates the sometimes unrealistic behaviour of the IDM in cut-in situations with ensuing small gaps that regularly are caused by lane changes of other vehicles in dense or congested traffic.

Adaptive cruise control design for active congestion avoidance
TL;DR: It is found that the ACC vehicles improve the traffic stability and the dynamic road capacity, and traffic congestion in the reference scenario was completely eliminated when simulating a proportion of 25% ACC vehicles.
