Exploratory analysis of an optimal variable speed control system for a recurrently congested freeway bottleneck
This study presents two models for proactive variable speed limit (VSL) control on a recurrently congested freeway segment. The proposed model uses embedded traffic flow relations to predict the evolution of congestion patterns over the projected time horizon, and then computes the time-varying optimal speed limit to smooth traffic flows. To contend with the uncertainties associated with driver...
متن کاملNovel Freeway Traffic Control with Variable Speed Limit and Coordinated Ramp Metering
control freeway traffic in the United States, particularly in California. It is recognized that ramp metering can directly control the flow into the freeway (demand) and the average density immediately downstream, which indirectly affects the traffic upstream. After drivers enter the freeway, their collective behaviors are not controlled, which determines the traffic flow pattern. In addition, ...
متن کاملSpeed Compliance in Freeway Variable Speed Limit System – Case Study of the Prague City Ring
Many previous studies have confirmed the strong relationship between speed compliance and the frequency and severity of traffic accidents. Variable speed limit (VSL) system as a measure to improve traffic safety enables the freeway system to change its posted speed limit based on various traffic and environmental conditions. Such system helps drivers to recognize the upcoming events, to adjust ...
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...
