This project contains three major parts. In the first part a digital computer simulation model was developed with the aim to model the traffic through a freeway work zone situation. The model was … [Read more...] about Phase II – Improved Work Zone Design Guidelines and Enhanced Model of Travel Delays in Work Zones
Traffic Queuing
QuickZone: Modeling in the Zone
While reducing congestion and increasing mobility have always been concerns in work-zone construction, these two concerns have received increased attention as the number of road repair projects … [Read more...] about QuickZone: Modeling in the Zone
Queuing and Natural Diversion at Short-Term Freeway Work Zone Lane Closures
Research conducted to explore the effects of natural diversion on traffic conditions and travel patterns upstream of temporary work zone lane closures on high-volume urban freeways in Texas is … [Read more...] about Queuing and Natural Diversion at Short-Term Freeway Work Zone Lane Closures
Proposed Model for Predicting Motorist Delays at Two-Lane Highway Work Zones
Maintenance activity on two-lane highways often requires the closure of one travel lane. Vehicles in both directions of travel are served via the one remaining lane. Under such conditions, alternating … [Read more...] about Proposed Model for Predicting Motorist Delays at Two-Lane Highway Work Zones
Estimation of Traffic Delays and Vehicle Queues at Freeway Work Zones
The traffic flow is disrupted and delayed at a work zone because the traffic capacity and the vehicle speed are lower at the work zone section than at other portions of the roadway. Traffic delays at … [Read more...] about Estimation of Traffic Delays and Vehicle Queues at Freeway Work Zones
