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
Real-Time Work Zone Traffic Management via Unmanned Air Vehicles
Highway work zones are prone to traffic accidents when congestion and queues develop. Vehicle queues expand at a rate of 1 mile every 2 minutes. Back-of-queue, rear-end crashes are the most common … [Read more...] about Real-Time Work Zone Traffic Management via Unmanned Air Vehicles
