Traffic Models

Work Zone Safety: Behavioral Analysis With Integration of VR and Hardware in the Loop (HIL)

Although there have been efforts to achieve the zero deaths on horizontal construction projects, undesired crashes within work zones continue to happen, highlighting the need for continuous studies on … [Read more...] about Work Zone Safety: Behavioral Analysis With Integration of VR and Hardware in the Loop (HIL)

Management of Connected and Automated Vehicle Disengagements in the Proximity of Work Zones

Work zones (WZ) incur profound impacts in the safety, mobility and environmental realms. Researchers and transportation agencies have exerted significant efforts in mitigating their adverse impacts … [Read more...] about Management of Connected and Automated Vehicle Disengagements in the Proximity of Work Zones

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

How Does the Value of Time Influence Road User Costs During Work Zone Closures? A Case Study in El Paso, Texas, Using Simulation-Based Modeling Methods

It is becoming standard practice for many departments of transportation (DOTs) to use incentive/disincentive clauses (also known as road user costs) with contractors to stay on or ahead of schedule. … [Read more...] about How Does the Value of Time Influence Road User Costs During Work Zone Closures? A Case Study in El Paso, Texas, Using Simulation-Based Modeling Methods

Estimation of Traffic Demand at Freeway Work Zones

An iterative process, combining a macroscopic simulator and a set of the traffic demand-change estimation models, is developed to estimate the traffic demand at work zones in urban freeway corridors. … [Read more...] about Estimation of Traffic Demand at Freeway Work Zones

Traffic Wave Models for the Urban Road With a Work Zone

The work zones greatly change the traffic wave characteristics on the urban road and further significantly influence the signal timing schemes. However, studies on the traffic wave under the influence … [Read more...] about Traffic Wave Models for the Urban Road With a Work Zone
