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
Traffic Flow
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
Integration of Real-Time Air Pollution Parameters into the Decision Making Process Regarding Highway Construction Work Zone Traffic Flow
The Midac Fourier Transform Infrared air monitoring system was used to measure real-time vehicular exhaust emission concentrations of carbon monoxide (CO) and hydrocarbons (HCs) during the Purdue … [Read more...] about Integration of Real-Time Air Pollution Parameters into the Decision Making Process Regarding Highway Construction Work Zone Traffic Flow
Evaluating Steady-State Assumption for Highway Queueing System
Stochastic queueing methods are often applied to highway systems to estimate performance characteristics such as delay and queue length. Inherent in stochastic queueing methods is the assumption that … [Read more...] about Evaluating Steady-State Assumption for Highway Queueing System
Traffic Management Strategies for Merge Areas in Rural Interstate Work Zones
Applying better management practices requires knowledge of the traffic flow properties and driver behavior in and around work zones, and knowledge of possible management strategies. The project … [Read more...] about Traffic Management Strategies for Merge Areas in Rural Interstate Work Zones
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
