Scheduling Work Zones in Multi-Modal Networks, Phase I: Scheduling Work Zones in Transportation Service Networks
The purpose of this project is to study the optimal scheduling of work zones so that they have minimum negative impact (e.g., travel delay, gas consumption, accidents, etc.) on transport service … [Read more...] about Scheduling Work Zones in Multi-Modal Networks, Phase I: Scheduling Work Zones in Transportation Service Networks
Optimal Trade-Offs between Construction Cost and Traffic Delay for Highway Work Zones
Highway work zones often cause traffic congestion, resulting in increased road-user delays and vehicle emissions. These negative impacts of highway work zones can be minimized by a number of … [Read more...] about Optimal Trade-Offs between Construction Cost and Traffic Delay for Highway Work Zones
Optimizing Scheduling of Long-Term Highway Work Zone Projects
The impacts of work zone activities can be summarized into the following types: safety impact (on both motorists and workers), mobility impact, economic considerations, environmental concerns, user … [Read more...] about Optimizing Scheduling of Long-Term Highway Work Zone Projects
Application of Work Zone Road User Costs to Determine Schedule-Related Incentives and Disincentives: Conceptual Framework
Time-related contract clauses are primarily designed to encourage contractors through incentives and disincentives to complete construction projects on or ahead of schedule. Highway agencies have … [Read more...] about Application of Work Zone Road User Costs to Determine Schedule-Related Incentives and Disincentives: Conceptual Framework
Work Zone Planning in Pavement Rehabilitation: Integrating Cost, Duration, and User Effects
This paper describes a methodology developed to support decision makers in planning work zones for pavement maintenance and rehabilitation interventions, integrating cost, duration, and user effects. … [Read more...] about Work Zone Planning in Pavement Rehabilitation: Integrating Cost, Duration, and User Effects
