Understanding Traffic Flow Characteristics and Capacity of Linear Multi-work Zones on the Urban Arterial Road
It is quite common that several construction projects are implemented synchronously on the urban arterial roads of many large cities in China. Unfortunately, despite the popularity and prevalence of … [Read more...] about Understanding Traffic Flow Characteristics and Capacity of Linear Multi-work Zones on the Urban Arterial Road
Impact of Temporary Portable Work Zone and Personal Lighting on Vehicle Speeds in Nighttime Highway Preservation Projects
Every year thousands of people are killed or injured in work zone crashes in the US due to excessive speed, distraction, inattentiveness, or low visibility. Many highway construction, maintenance, and … [Read more...] about Impact of Temporary Portable Work Zone and Personal Lighting on Vehicle Speeds in Nighttime Highway Preservation Projects
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
