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
A Smart Highway Work Zone Merge System Enabled by Connected Vehicles
Typical traffic control and operations at work zones usually are not very effective in mitigating the work zone bottleneck. A major reason is that the common early merge behaviors limits utilizing the … [Read more...] about A Smart Highway Work Zone Merge System Enabled by Connected Vehicles
Capacity Modeling and Control Optimization for a Two-Lane Highway Lane-Closure Work Zone
A two-lane highway lane closure work zone is a unique work zone type because of its traffic impact. When one lane of traffic is blocked, it is necessary to implement a traffic control strategy to … [Read more...] about Capacity Modeling and Control Optimization for a Two-Lane Highway Lane-Closure Work Zone
Estimation of Saturation Headway in Work Zones on Urban Streets
Work zones and lane closures on urban arterials can cause significant disruptions to the traveling public, and methods are increasingly needed to estimate the reductions to saturation flow rates that … [Read more...] about Estimation of Saturation Headway in Work Zones on Urban Streets
