User Cost Model of Highway Work Zone During Discrete Periods Under Influence of Uncertain Factors
The traffic situation of highway work zone during discrete periods was analyzed. By dispersing the work periods, the relationships between the capacities of work zones and user costs during different … [Read more...] about User Cost Model of Highway Work Zone During Discrete Periods Under Influence of Uncertain Factors
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
Modelling Major Traffic Incident Impacts and Estimation of Their Associated Costs
Network area-wide impacts due to major traffic incidents can be assessed using a microsimulation approach. A VISSIM microsimulation model for a motorway network has been developed and is used to … [Read more...] about Modelling Major Traffic Incident Impacts and Estimation of Their Associated Costs
Evaluation of Cost-Effectiveness of Steady-Burn Warning Lights in Work Zones
The 2009 Manual on Uniform Traffic Control Devices (MUTCD) recognizes the potential safety benefit of providing enhanced delineation on temporary traffic control (TTC) devices and allows for warning … [Read more...] about Evaluation of Cost-Effectiveness of Steady-Burn Warning Lights in Work Zones
Effectiveness of Work Zone Intelligent Transportation Systems
In the last decade, Intelligent Transportation Systems (ITS) have increasingly been deployed in work zones by state departments of transportation. Also known as smart work zone systems they improve … [Read more...] about Effectiveness of Work Zone Intelligent Transportation Systems
