Lighted Guidance Devices: Intelligent Work Zone Traffic Control
Annually, thousands of highway workers risk serious injury and death from drivers who enter work zones too fast or accelerate after entering the zone and then, because of their excess speed relative … [Read more...] about Lighted Guidance Devices: Intelligent Work Zone Traffic Control
Traffic Flow Characteristics of the “Late Merge” Work Zone Control Strategy
Conventional traffic control plans such as the one used in Nebraska ( NDOR Merge) for lane closures of rural Interstate highways normally work well as long as congestion does not develop. However, … [Read more...] about Traffic Flow Characteristics of the “Late Merge” Work Zone Control Strategy
Flow Characteristics at Freeway Work Zones and Increased Deterrent Zones
Traffic-flow characteristics were studied at two work zones on suburban freeways and at a third freeway site where a police patrol car, easily noticed by drivers, was parked on the right shoulder. The … [Read more...] about Flow Characteristics at Freeway Work Zones and Increased Deterrent Zones
