Due to the rising needs in highway maintenance and construction, the number of work zones is increasing throughout the United States. Highway work zones disrupt normal traffic flow and create safety … [Read more...] about Determining the Effectiveness of PCMS on Reducing Vehicle Speed in Rural Highway Work Zones
Road User Impacts Due to Speed Limit Reduction in Work Zones: Which Tool Is Best: Quickzone or Visum?
The Utah Department of Transportation (UDOT) ExpressLink project on I−15 will increase capacity by adding express lanes in each direction from 500 North to I−215 ramp in Davis County, Utah. These … [Read more...] about Road User Impacts Due to Speed Limit Reduction in Work Zones: Which Tool Is Best: Quickzone or Visum?
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
Sequential Advanced Guide Signing for Work Zone Related Rerouting on Highways: The Effect of Longitudinal Location on the Driver’s Trajectory Control
This study examined the effects of a sequenced triple (i.e., announcement, instruction, marker) sign configuration for advanced guidance in a work zone related rerouting scenario on longitudinal and … [Read more...] about Sequential Advanced Guide Signing for Work Zone Related Rerouting on Highways: The Effect of Longitudinal Location on the Driver’s Trajectory Control
Glare and Light Characteristics of Conventional and Balloon Lighting Systems
With the increasing needs to adopt nighttime construction strategies in order to avoid disruption of traffic flow, state agencies are currently experimenting with a new class of light towers known as … [Read more...] about Glare and Light Characteristics of Conventional and Balloon Lighting Systems
Optimization of Work Zone Schedule Considering Time-Varying Traffic Diversion
Highway maintenance may cause excessive delay on transportation corridors and networks. Diverting traffic from congested highway work zones and accelerating maintenance progress can mitigate the … [Read more...] about Optimization of Work Zone Schedule Considering Time-Varying Traffic Diversion
