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

The introduction of deep learning and big data analytics may significantly elevate the performance of traffic speed prediction. Work zones become one of the most critical factors causing congestion … [Read more...] about A Deep Machine Learning Approach for Predicting Freeway Work Zone Delay Using Big Data

Agile Work Zone Management Based on Probe Traffic Data

Peak period lane closures can result in significant queueing on major interstates. As a result, many state agencies have a lane closure policy in place based upon historical time of day and day of … [Read more...] about Agile Work Zone Management Based on Probe Traffic Data

Review of Methods for Estimating Construction Work Zone Capacity

Road reconstruction and the resulting work zones are considered as a major source of traffic congestion and delays on freeways. The roadway capacity is decreased as a result of a reduced number of … [Read more...] about Review of Methods for Estimating Construction Work Zone Capacity

Safety Analysis of Coordinated Warning Information in Construction Area of Expressway

Construction areas can easily cause traffic accidents and form traffic bottlenecks. In this study, based on driving simulation technology, a test platform for warning information of vehicle-road … [Read more...] about Safety Analysis of Coordinated Warning Information in Construction Area of Expressway
