Feedback Control of Scalar Conservation Laws with Application to Density Control in Freeways by Means of Variable Speed Limits
The paper provides results for the stabilization of a spatially uniform equilibrium profile for a scalar conservation law that arises in the study of traffic dynamics under variable speed limit control. Two different control problems are studied: the problem with free speed limits at the inlet and the problem with no speed limits at the inlet. Explicit formulas are provided for respective feedb...
متن کاملApplication of Variable Speed Limits and Ramp Metering to Improve Safety and Efficiency of Freeways
Research recently conducted at the University of Central Florida involving crashes on Interstate-4 (I-4) freeway in Orlando, Florida led to the creation of new statistical and neural networks models that are capable of determining rear-end and lane-change crash risks along the freeway in real-time. For determining the rear-end crash risk, it was found that rear-end crashes occur within one of t...
متن کاملDynamic traffic management on a familiar road: Failing to detect changes in variable speed limits
Variable speed limits (VSL) are used more commonly around the globe lately. Although on a macroscopic level positive effects of VSLs have been reported, the caveat is that the impact of VSLs is very sensitive to the level of driver compliance. Thus far it is unknown whether all individual drivers are actually able to notice when a speed limit changes into another speed limit; a prerequisite for...
متن کاملA Traffic Flow Simulation Model Based on the Desired Speed in Merging Sections on Freeways
In order to alleviate traffic congestions and environmental impact, developing a model to evaluate under various geometric and traffic conditions is desirable, which is the objective of this study. The car following model describes following behaviors that drivers follow each other in the traffic stream on only one lane. The lane change model is one of the essential components of any microscopi...
متن کاملDynamic Variable Speed Limit Strategies for Real-Time Crash Risk Reduction on Freeways
in the number and severity of shockwaves. The authors found that the implementation of variable speed limits provided calmer traffic and improved the distribution of the traffic over the available road space. In the United States, VSLs are used in Washington State, New Jersey, New Mexico, and Wisconsin to identify and implement a safe speed limit when inclement weather converges on vulnerable f...
