In Memorium: Rowland Ian Kingham (1933–2001)
Publisher: American Society of Civil Engineers
Estimating Incident Queue Impacts with and without a Traffic Surveillance System
Publisher: American Society of Civil Engineers
Abstract: Despite the needs of assessing the time-varying queue length for incident traffic management, such imperative information has not yet been available in practice, due partly to the lack of reliable sensor data on many ...
Variability Assessment for TRAF‐NETSIM
Publisher: American Society of Civil Engineers
Abstract: The presence of high variability in traffic simulation results often leads to concern about their reliability, and consequently precludes a rigorous evaluation of the target traffic system's performance under various control ...
Saturation Flow Rates and Maximum Critical Lane Volumes for Planning Applications in Maryland
Publisher: American Society of Civil Engineers
Abstract: This paper illustrates the field measurements of saturation flow headways and start-up lost times at 11 representative intersections in the state of Maryland. Based on those empirical results, this study has recommended ...
Decision Model for Justifying the Benefits of Detour Operation under Non-Recurrent Congestion
Publisher: American Society of Civil Engineers
Abstract: Non-recurrent traffic congestion due to incidents, highway construction zones, and special events has contributed up to 60% of the total freeway corridor delay in the United States. Under most scenarios, if proper diversion ...
Empirical Study of Driver Responses during the Yellow Signal Phase at Six Maryland Intersections
Publisher: American Society of Civil Engineers
Abstract: This paper presents the analysis results of driver responses during a yellow phase, based on field observations of 1,123 drivers collected with a specially designed system from six signalized intersections of high crash ...
Development of a Signal Optimization Model for Diverging Diamond Interchange
Publisher: American Society of Civil Engineers
Abstract: As one of the most popular unconventional interchange designs, diverging diamond intersection (DDI) has received increased attention over the past decade. Through a reverse operation of traffic movements between its two ...
Effects of 65‐MPH Speed Limit on Traffic Safety
Publisher: American Society of Civil Engineers
Abstract: In April 1987 the United States Congress passed the Surface Transportation and Uniform Relocation Assistance (STURA) Act that permitted the states to increase the speed limit on rural Interstate highways up to 65 mph. This ...
Two-Level Integrated Optimization System for Planning of Emergency Evacuation
Publisher: American Society of Civil Engineers
Abstract: This paper presents a two-level integrated optimization system for use in generating the candidate set of optimal evacuation plans that serve as the input for simulation-based evacuation systems. In the proposed system, ...
Lane-Based Dynamic Merge Control Strategy Based on Optimal Thresholds for Highway Work Zone Operations
Publisher: American Society of Civil Engineers
Abstract: Despite the potential effectiveness of the dynamic late merge (DLM) control, most existing DLM systems, based on static thresholds, cannot best perform under time-varying traffic conditions. This paper presents an advanced ...
