Modeling and Predicting Stochastic Merging Behaviors at Freeway On-Ramp Bottlenecks
Merging behavior is inevitable at on-ramp bottlenecks and is a significant factor in triggering traffic breakdown. In modeling merging behaviors, the gap acceptance theory is generally used. Gap … [Read more...] about Modeling and Predicting Stochastic Merging Behaviors at Freeway On-Ramp Bottlenecks
Compliance Crash Testing of the Type 60 Median Barrier
The California Department of Transportation has used Type 60 Median Barrier since it passed the National Cooperative Highway Research Program (NCHRP) Report 350 safety guidelines and became a Standard … [Read more...] about Compliance Crash Testing of the Type 60 Median Barrier
Work Zones and Temporary Traffic Organization at Roundabout – Review of Selected Solutions
In many countries roundabouts are becoming an increasingly common element of transportation infrastructure. Therefore, like other elements of the infrastructure, they may be subject to periodic … [Read more...] about Work Zones and Temporary Traffic Organization at Roundabout – Review of Selected Solutions
Merging Vehicles and Lane Speed-Flow Relationship in a Work Zone
In addition to closed merge lanes as physical bottlenecks of work zones, traffic oscillations caused by merging vehicles at multiple locations could reduce work zone capacity. This study took a … [Read more...] about Merging Vehicles and Lane Speed-Flow Relationship in a Work Zone
Time-varying Mixed Logit Model for Vehicle Merging Behavior in Work Zone Merging Areas
This study aims to develop a time-varying mixed logit model for the vehicle merging behavior in work zone merging areas during the merging implementation period from the time of starting a merging … [Read more...] about Time-varying Mixed Logit Model for Vehicle Merging Behavior in Work Zone Merging Areas
