This paper presents a methodology for optimizing performance of a traffic system on the basis of simulated observations of its microscopic behavior. The method integrates simulation and optimization … [Read more...] about Integrating Microscopic Simulation and Optimization: Application to Freeway Work Zone Traffic Control

Technology in Rural Transportation, “Simple Solution” #7 – Lane Drop Driver Awareness
Lane drops occur as a result of restricting roadways caused by construction work or other planned or unplanned events. When vehicles fail to merge in a timely fashion, delays or traffic accidents … [Read more...] about Technology in Rural Transportation, “Simple Solution” #7 – Lane Drop Driver Awareness
Indiana Lane Merge System for Work Zones on Rural Freeways
The Indiana Department of Transportation and Purdue University have been investigating and implementing a novel traffic control system at two-lane freeway work zone entries to reduce the number of … [Read more...] about Indiana Lane Merge System for Work Zones on Rural Freeways
Traffic Flow Characteristics of the “Late Merge” Work Zone Control Strategy
Conventional traffic control plans such as the one used in Nebraska ( NDOR Merge) for lane closures of rural Interstate highways normally work well as long as congestion does not develop. However, … [Read more...] about Traffic Flow Characteristics of the “Late Merge” Work Zone Control Strategy
Indiana Lane Merge System
The Indiana Lane Merge (ILM) System is a new tool that was developed to remedy the safety and efficiency problems created by closing a lane on an interstate highway. The main problem addressed is a … [Read more...] about Indiana Lane Merge System
Georgia Finds Better Alternative for Directing Traffic Through Taper Lanes
Highway maintenance often forces the Georgia Department of Transportation (DOT) to temporarily close lanes of traffic. In these situations, the DOT usually deploys a series of barrels to show drivers … [Read more...] about Georgia Finds Better Alternative for Directing Traffic Through Taper Lanes
