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

Time-Dependent Transportation Network Design Considering Construction Impact

A traditional discrete network design problem (DNDP) always assumes transportation infrastructure projects to be one-time events and ignores travelers’ delays caused by construction work. In fact, … [Read more...] about Time-Dependent Transportation Network Design Considering Construction Impact

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

Analysis on Work Zone Characteristics in South Korean Expressways Using Text Mining Technique

The study proposes the association between work zone types and work zone lane closure types used in the construction of South Korean expressways through the use of the text mining and association … [Read more...] about Analysis on Work Zone Characteristics in South Korean Expressways Using Text Mining Technique
