Traffic Flow

 

Integrated Control Method for Ramp Traffic Flow in Construction Area of Expressway

In order to alleviate the traffic congestion of the expressway construction section without interrupting the traffic, an integrated control method of ramp traffic flow was proposed. Based on METANET … [Read more...] about Integrated Control Method for Ramp Traffic Flow in Construction Area of Expressway

Methodology for Applying Connected Vehicle Data to Evaluate Impact of Interstate Construction Work Zone Diversions

Diversion of Interstate traffic can significantly impact the surrounding road network with increased volumes and congestion. This paper uses commercially available connected vehicle data to examine … [Read more...] about Methodology for Applying Connected Vehicle Data to Evaluate Impact of Interstate Construction Work Zone Diversions

Characterizing Interstate Crash Rates Based on Traffic Congestion Using Probe Vehicle Data

Crash reduction factors are widely used by engineers for prioritizing safety investments. Work zones are routinely analyzed by the length and duration of queues. Queue detection warning technology has … [Read more...] about Characterizing Interstate Crash Rates Based on Traffic Congestion Using Probe Vehicle Data

Optimization of Lane-Changing Advisory of Connected and Autonomous Vehicles at a Multi-Lane Work Zone

The work zone with lane closure will be an active bottleneck due to vehicles’ mandatory lane-changing conflicts. The emerging Connected Autonomous Vehicle (CAV) technology provides opportunities for … [Read more...] about Optimization of Lane-Changing Advisory of Connected and Autonomous Vehicles at a Multi-Lane Work Zone

Continued Updating the Lane Closure Guide for Urban Highways in the Kansas City, Kansas, Metropolitan Area

Temporary work zones in the United States continue to be an important and necessary aspect of preserving, expanding, and maintaining the roadway infrastructure network. However, work zones present a … [Read more...] about Continued Updating the Lane Closure Guide for Urban Highways in the Kansas City, Kansas, Metropolitan Area

Modeling Traffic Flow in Work Zone Sections Considering the Effect of Traffic Lights

The relationship between the vehicles’ queuing time and the cycle of traffic lights is studied, and the cycle time of traffic lights is obtained also considering people’s endurance to the red light. … [Read more...] about Modeling Traffic Flow in Work Zone Sections Considering the Effect of Traffic Lights
