Micro-Level Analysis on Traffic Flow Parameters at Work-Zone Road Section Using Vehicular Trajectory Data

The research work is carried out to examine microscopic and macroscopic traffic parameters at work zone on high speed urban roads. Due to construction of elevated metro rail project over the study … [Read more...] about Micro-Level Analysis on Traffic Flow Parameters at Work-Zone Road Section Using Vehicular Trajectory Data

Safety Impacts of Signalized Lane Merge Control at Highway Work Zones

Lane closures due to highway work zones present many challenges to the goal of ensuring smooth traffic operations and a safe environment for both drivers and workers. Late merge behavior at a work … [Read more...] about Safety Impacts of Signalized Lane Merge Control at Highway Work Zones

Optimal Variable Speed Limit Control under Connected Work Zone and Connected Vehicle Environment

Despite the long-term benefits gained through road maintenance projects, the work zone involved can cause serious traffic congestion and greatly increase traffic delay. Variable speed limit (VSL) … [Read more...] about Optimal Variable Speed Limit Control under Connected Work Zone and Connected Vehicle Environment
