Development and Testing of Variable Speed Limit Control Logics for Work Zones Using Simulation
This study is an attempt to evaluate the performance of various speeds at work zones and to develop VSL control logics that would calculate suitable speeds for different traffic conditions. The … [Read more...] about Development and Testing of Variable Speed Limit Control Logics for Work Zones Using Simulation
Approximated Headway Distributions of Free-Flowing Traffic on Ohio Freeways for Work Zone Traffic Simulations
Headway or interarrival time (IAT) data of successive vehicles in free-flowing traffic ahead of work zones at six different Ohio freeways (two with two lanes in one direction, three with three lanes, … [Read more...] about Approximated Headway Distributions of Free-Flowing Traffic on Ohio Freeways for Work Zone Traffic Simulations
Accelerating Major Freeway Reconstruction Projects: The Houston Experience
Several steps in the planning, execution, and evaluation of the I-45 Pierce Elevated reconstruction in Houston provide a strong framework for preparing for projects that affect critical links in the … [Read more...] about Accelerating Major Freeway Reconstruction Projects: The Houston Experience
