RISGeneralized Capacity Estimation Model for Weaving Areas
Publisher: American Society of Civil Engineers
Abstract: Weaving areas are one of the major highway facilities that have long been investigated by researchers. Their capacities are currently estimated based on the density
Maximizing the Traffic Throughput of Turn Bays at a Signalized Intersection Approach
Publisher: American Society of Civil Engineers
Abstract: This paper proposes a method to maximize the throughput of a single-lane approach with a branched configuration (one-lane arterial with multiple turn bays at the intersection approach). Field observations determined that, ...
Optimizing Freeway Merge Operations under Conventional and Automated Vehicle Traffic
Publisher: ASCE
Abstract: This paper presents an optimization algorithm for freeway operations at merge zones that maximizes the average speed of the segment in the presence of connected and automated vehicles (CAVs) and human-operated (i.e.,&nbs ...
Some Guidelines for Selecting Microsimulation Models for Interchange Traffic Operational Analysis
Publisher: American Society of Civil Engineers
Abstract: There are several commercially available traffic simulation packages that are able to model the full range of interchange ramp terminals. Each of these packages has pros and cons for simulating various types of interchanges ...
Development of an Optimization Methodology for Adaptive Traffic Signal Control at Diamond Interchanges
Publisher: American Society of Civil Engineers
Abstract: This research develops a methodology and a corresponding implementation algorithm to provide optimal signal control of diamond interchanges in response to real-time traffic fluctuations. The problem is formulated as to ...
Exploratory Analysis of Lane Changing on Freeways Based on Driver Behavior
Publisher: American Society of Civil Engineers
Abstract: Lane changing has received much attention as it is a significant component of microscopic traffic simulation. Many studies have focused on the details of the lane changing maneuver from external observation-based data which ...
Differences in Freeway Capacity by Day of the Week, Time of Day, and Segment Type
Publisher: American Society of Civil Engineers
Abstract: Capacity has traditionally been defined deterministically, and has been assumed to occur immediately before breakdown. Recent studies, however, have shown that the value of capacity, i.e., maximum throughput, is probabilistic, ...
Assessment of Safety and Traffic Operational Quality for Historic Stone Bridges
Publisher: American Society of Civil Engineers
Abstract: This paper presents the methodology developed for assessing the safety and traffic operational quality of 92 stone arch bridges within Hunterdon County, New Jersey. The methodology presented here was developed as part of ...
Effects of Traffic Characteristics and Mounting Location on the Visibility of On-Premise Commercial Signs
Publisher: American Society of Civil Engineers
Abstract: In recent years, there has been a movement in local government regulations toward restricting the mounting height of on-premise, commercial signing and other roadside oriented signs. This has caused some concern among sign ...
