“…The microscopic models which have been extensive studied are the so-called vehicle-follower models, where the behavior of each vehicle is specified in terms of the vehicle immediately ahead. Such models have been used in simulating mostly single-lane traffic and automatic longitudinal/lateral vehicle control of individual vehicles (see [1], [6], [10], [12], [24], and [25]). These models (in their continuum formulation) involve ordinary differential equations describing the movement of each individual vehicle following the vehicle ahead.…”

This article studies the usefulness of parallel processing in real-time traffic-flow simulation based on continuum modeling of traffic dynamics. Computational fluid dynamics (CFD's) methods for solving simple macroscopic traffic-flow continuum models have been studied and efficiently implemented in traffic simulation codes (on serial computers) in the past. We designed a traffic-flow simulation code and mapped it onto a parallel computer architecture. This traffic simulation system is capable of simulating freeway traffic flow in real time. Tests with real traffic data collected from the freeway network in the metropolitan area of Minneapolis, MN, were used to validate the accuracy and computational rate of the parallel simulation system. The execution time for a 2-h traffic-flow simulation of about 200 619 vehicles in an 18-mi freeway, which takes 2.35 min of computer time (on a single-processor computer simulator), took only 5.25 s on the parallel traffic simulation system. This parallel system has a lot of potential for real-time traffic engineering applications.

Base on researching the source and development of fault tolerance theory, this paper discusses the working mechanism of fault tolerance, and illustrates the workflow and dependability of fault tolerance. So there is a widespread belief that this is feasible that fault tolerance theory is used in the traffic safety study. Through summarizing the progress of the fault-tolerant study in road traffic field at home and abroad, the paper gets some enlightenment from these literatures, finally gives the prospect of fault-tolerant theory which is used in the road traffic safety research.

“…The Intelligent Vehicle/Highway System (IVHS) and Areawide Real-time Traffic Control (ARTC) had been gotten attention twenty years ago ( [1], [2]). And automated highway (AHS) or cooperative vehicle highway systems (CVHS) are under development to enhance utilization, reduce journey times and improve usage of energy (see [3] and the references therein).…”

The safety and comfort control of vehicles in certain cases is considered in this paper. We hope to use detectors plus advanced control methods to realize the satisfactory tracking control, even the proper velocity and acceleration control of vehicles. Because of the intrinsically nonlinear, highly plant uncertain of vehicles and closely interconnected among vehicles, here the method based on the new separation principle (NSP) of tuning PID controller is used. First, the control method is extended to systems with variable control gain and delay in control input. It is the method that, without using of estimator or observer, we can reject system's uncertain parts, disturbances or interconnected parts effectively. So the structure of the control system is relatively a simple one. Second, as its application, we use the results for the control of vehicles in three cases, such as in case of emergency, moving in platoon form and with delay in control input. It is the robustness of the method that, by using little information, we can still get rather good control performance, especially for high accuracy desired output tracking of velocity and acceleration, even with a good transient response. And some simulation results for the comparison of relative positions, velocities and accelerations are shown to demonstrate the efficiency of the method.
