Traffic Control at Flagger-Operated Work Zones on Two-Lane Roads
To clarify the traffic flow characteristics and the signal timings at work zones controlled by flaggers, traffic flows at some work zones were measured. Using the measurement data a computer … [Read more...] about Traffic Control at Flagger-Operated Work Zones on Two-Lane Roads
Dealing with the Traffic Impacts of Urban Freeway Reconstruction: Mitigation Measures
The following six areas of impact come quickly to mind when discussing plans for managing traffic in highway construction zones: (1) Actual delay to motorists, especially peak period commuters, … [Read more...] about Dealing with the Traffic Impacts of Urban Freeway Reconstruction: Mitigation Measures
Traffic Control Management Through Construction Zones
As I-70 construction activities in Colorado's Glenwood Canyon intensified, it became increasingly clear that traditional approaches to construction traffic control could neither efficiently nor safely … [Read more...] about Traffic Control Management Through Construction Zones
Delay Messages and Delay Tolerance at Houston Work Zones (abridgement)
A questionnaire survey of freeway drivers in Houston was conducted at six locations: I-10 W, I-10 E, I-45 N, I-45 S, US-59 S, and US-59 N. The questionnaire data were based on a license-plate survey … [Read more...] about Delay Messages and Delay Tolerance at Houston Work Zones (abridgement)
Lane Closures at Freeway Work Zones: Simulation Study
A study of freeway lane closures at work zones is described. It involved the development of a microscopic computer-simulation model. Vehicles in platoons are controlled by a car-following rule. The … [Read more...] about Lane Closures at Freeway Work Zones: Simulation Study
