Variable Speed Limit Systems: Safety and Operational Impacts for Freeways Applications

A candidate Variable Speed Limits Sign (VSLS) control algorithm was applied to an urban freeway in Toronto, Canada using microsimulation. The microsimulation model was combined with a categorical crash model to quantify the impacts of VSLS implementation on safety and traffic performance. The VSLS control strategy was developed as a practical algorithm that responded to real-time measures of tr...

development and implementation of an optimized control strategy for induction machine in an electric vehicle

in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...

Assessing Safety Benefits of Variable Speed Limits

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...
