Passenger Car Equivalents for Heavy Vehicles in Work Zones
There are no Passenger Car Equivalents (PCE) values developed for work zones. Consequently the PCE values of basic freeway section are borrowed despite the reservations about their applicability to … [Read more...] about Passenger Car Equivalents for Heavy Vehicles in Work Zones
Effect of Work Zone Length and Speed Difference Between Vehicle Types on Delay-Based Passenger Car Equivalents in Work Zones
This paper presents how Delay-based Passenger Car Equivalent (D-PCE) values of heavy vehicles in work zones vary with work zone length, speed difference between vehicle types, heavy vehicle type, … [Read more...] about Effect of Work Zone Length and Speed Difference Between Vehicle Types on Delay-Based Passenger Car Equivalents in Work Zones
Field Evaluation of Work-Zone Automated Speed Enforcement Equipment and Traffic Monitoring Devices
Speeding is a significant contributor to a significant portion of highway collisions. For work zones in particular, the speeding problem is compounded by on-site road re-configuration, narrowed lanes, … [Read more...] about Field Evaluation of Work-Zone Automated Speed Enforcement Equipment and Traffic Monitoring Devices
Evaluation of a Motorist Awareness System
The objective of this study was to determine the effects of a Motorist Awareness System (MAS) on vehicle speeds in highway work zones. Spot speed studies were conducted prior to, within, and near the … [Read more...] about Evaluation of a Motorist Awareness System
Modeling Speed Behavior of Passenger Cars and Trucks in Freeway Construction Work Zones: Implications on Work Zone Design and Traffic Control Decision Processes
Current work zone design and traffic control guidance is based on desirable speed outcomes; knowledge related to actual speed outcomes of design and traffic control decisions is limited. The objective … [Read more...] about Modeling Speed Behavior of Passenger Cars and Trucks in Freeway Construction Work Zones: Implications on Work Zone Design and Traffic Control Decision Processes
