Study on the Length of Median Opening in Expressway Reconstruction and Extension Work Zones
The opening length and influencing factors were studied aiming at the traffic of the two lanes at median opening section in expressway reconstruction and extension work zones. Based on the analysis of … [Read more...] about Study on the Length of Median Opening in Expressway Reconstruction and Extension Work Zones
Collision Avoidance Analysis for Transition Taper Length
Transition taper length plays a vitally important role in work zone safety operations because too short a transition taper length will result in higher accident risks and too long a transition taper … [Read more...] about Collision Avoidance Analysis for Transition Taper Length
Optimal Work Zone Lengths and Signal Timing for Two-Lane Highways Revisited: The Need to Consider Stochasticity
Work zones can give rise to significant costs, both to maintenance agencies as well as to road users. In this paper we focus on the optimal configuration of work zones on two-lane highways. While … [Read more...] about Optimal Work Zone Lengths and Signal Timing for Two-Lane Highways Revisited: The Need to Consider Stochasticity
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
