Traffic Flow

Characterizing Interstate Crash Rates Based on Traffic Congestion Using Probe Vehicle Data

Crash reduction factors are widely used by engineers for prioritizing safety investments. Work zones are routinely analyzed by the length and duration of queues. Queue detection warning technology has … [Read more...] about Characterizing Interstate Crash Rates Based on Traffic Congestion Using Probe Vehicle Data

Optimization of Lane-Changing Advisory of Connected and Autonomous Vehicles at a Multi-Lane Work Zone

The work zone with lane closure will be an active bottleneck due to vehicles’ mandatory lane-changing conflicts. The emerging Connected Autonomous Vehicle (CAV) technology provides opportunities for … [Read more...] about Optimization of Lane-Changing Advisory of Connected and Autonomous Vehicles at a Multi-Lane Work Zone

Continued Updating the Lane Closure Guide for Urban Highways in the Kansas City, Kansas, Metropolitan Area

Temporary work zones in the United States continue to be an important and necessary aspect of preserving, expanding, and maintaining the roadway infrastructure network. However, work zones present a … [Read more...] about Continued Updating the Lane Closure Guide for Urban Highways in the Kansas City, Kansas, Metropolitan Area

Modeling Traffic Flow in Work Zone Sections Considering the Effect of Traffic Lights

The relationship between the vehicles’ queuing time and the cycle of traffic lights is studied, and the cycle time of traffic lights is obtained also considering people’s endurance to the red light. … [Read more...] about Modeling Traffic Flow in Work Zone Sections Considering the Effect of Traffic Lights

CARMA: Improving Traffic Flows and Safety at Active Work Zones

Federal Highway Administration’s CARMASM Program is leading research on the information exchanges and cooperative maneuvers that constitute cooperative driving automation (CDA).  The work zone … [Read more...] about CARMA: Improving Traffic Flows and Safety at Active Work Zones

A Deep Machine Learning Approach for Predicting Freeway Work Zone Delay Using Big Data
