Freeway Work Zone Free-Flow Speed Model Development
Freeways with uninterrupted flow are expected to provide seamless movement of traffic resulting in reliable and safe travel conditions with a high level of service. In a time of aging transportation … [Read more...] about Freeway Work Zone Free-Flow Speed Model Development
Impacts of Night-Time Work-Zone Speed Restrictions on Freeway Speed Characteristics: A Case Study on Edmonton, Canada
Freeway work zone is considered as a potentially hazardous zone, which asks for special speed restriction to provide a relatively safe environment for road users and workers. However, the efficacy of … [Read more...] about Impacts of Night-Time Work-Zone Speed Restrictions on Freeway Speed Characteristics: A Case Study on Edmonton, Canada
Drivers’ Lane Change Maneuver and Speed Behavior in Freeway Work Zones
Lane changing and merging occurs more frequently in work zones than other roadway conditions due to mandatory lane changes that occur in work zones with lane closures. Discretionary lane changes are … [Read more...] about Drivers’ Lane Change Maneuver and Speed Behavior in Freeway Work Zones
Advantages and Challenges of a Video-Based Experiment to Investigate Drivers’ Speed Choice at Work Zones
This paper reports part of a larger study conducted in Norway about speed choice at roadworks. The method utilized was four videos of real work zones. One urban road and one rural road were filmed at … [Read more...] about Advantages and Challenges of a Video-Based Experiment to Investigate Drivers’ Speed Choice at Work Zones
Evaluation of Mobility Impact on Urban Work Zones Using Statistical Models
This work correlated the detailed work zone location and time data from the WisLCS system with the five-min inductive loop detector data. One-sample percentile value test and two-sample … [Read more...] about Evaluation of Mobility Impact on Urban Work Zones Using Statistical Models
