Approximated Headway Distributions of Free-Flowing Traffic on Ohio Freeways for Work Zone Traffic Simulations
Headway or interarrival time (IAT) data of successive vehicles in free-flowing traffic ahead of work zones at six different Ohio freeways (two with two lanes in one direction, three with three lanes, … [Read more...] about Approximated Headway Distributions of Free-Flowing Traffic on Ohio Freeways for Work Zone Traffic Simulations
Pavement Resurfacing Intervals in Work Zone Optimization
Lane closures for highway resurfacing involve some intricate tradeoffs between the maintenance cost to highway agencies and the costs of delays and disruptions to motorists. Careful optimization of … [Read more...] about Pavement Resurfacing Intervals in Work Zone Optimization
In-Depth Analysis of Vehicle Following Gaps in Highway Work Zones: Direct and Interdependent Impact of Leading Vehicle
This paper analyzes the impacts of various vehicle following patterns on the vehicle following distance/gap in highway work zones. It studies the direct impact of leading vehicle on the vehicle … [Read more...] about In-Depth Analysis of Vehicle Following Gaps in Highway Work Zones: Direct and Interdependent Impact of Leading Vehicle
Evaluation of Strategies to Manage Speed in Highway Work Zones
Safety in reconstruction and maintenance work zones continues to be the primary concern of transportation engineers. Speeding is one of the major contributors of work zone crashes. To decrease the … [Read more...] about Evaluation of Strategies to Manage Speed in Highway Work Zones
Field Evaluation of Variable Advisory Speed Limit System for Reducing Traffic Conflicts at Work Zones
A practical methodology to reduce the traffic conflicts at work zones was developed and evaluated in the field. The proposed system uses variable advisory speed limits that are determined with a … [Read more...] about Field Evaluation of Variable Advisory Speed Limit System for Reducing Traffic Conflicts at Work Zones
