RISInfluence of Restricted Sight Distances on Permitted Left-Turn Operation at Signalized Intersections
Publisher: American Society of Civil Engineers
Abstract: Adequate sight distance is an important factor needed to provide safe and efficient operation of left-turn movements at signalized intersections. This factor becomes more crucial for left turners attempting this maneuver ...
New Taxi–Passenger Dispatching Model at Terminal Station
Publisher: American Society of Civil Engineers
Abstract: The taxi–passenger problem is more and more prominent in terminal stations; passengers usually wait in a long queue for taking a taxi in rush hour, and otherwise taxis wait in a queue for passengers. Nevertheless, there ...
Disentangling City-Level Macroscopic Traffic Performance Patterns through a Trigonometric Multiseasonal Filtering Algorithm: Inspiration from Big Data of Ride-Sourcing Trips
Publisher: ASCE
Abstract: This study seeks to design a city-level trip speed performance index (CTSPI) providing an alternative aspect in quantifying the traffic performance of an entire city. Another objective is to disentangle the original CTSPI ...
Applying and Evaluating Data-Driven Fine Grid Partitioning Methods for Traffic Analysis Zones
Publisher: ASCE
Abstract: Fine grid management is one of the important development directions of transportation planning that has not been fully considered in previous literature. This paper explores the application of the fine grid management ...
Geometric Models to Calculate Left-Turn Sight Distance for Signalized Intersections on Horizontal Curves
Publisher: American Society of Civil Engineers
Abstract: At signalized intersections where protected left turn signals are not provided, simultaneous opposing left-turn vehicles may cause insufficient sight distance for each other. There is a lack of literature presenting left-turn ...
Cost-Effectiveness Analyses of Maintenance Treatments for Low- and Moderate-Traffic Asphalt Pavements in Tennessee
Publisher: American Society of Civil Engineers
Abstract: The effectiveness and cost-effectiveness of resurfacing maintenance treatments applied to low- and moderate-traffic asphalt pavements in Tennessee were evaluated based on the pavement condition data and costs of identified ...
Evaluation of Dynamic Passing Sight Distance Problem Using a Finite-Element Model
Publisher: American Society of Civil Engineers
Abstract: Sufficient passing sight distance is an important control for two-lane rural highway design to minimize the possibility of a head-on collision between passing and opposing vehicles. Traditionally, passing zones are marked ...
Analysis of Sideswipe Collision Precursors Considering the Spatial-Temporal Characteristics of Freeway Traffic
Publisher: American Society of Civil Engineers
Grid Mapping for Road Network Abstraction and Traffic Congestion Identification Based on Probe Vehicle Data
Publisher: ASCE
Abstract: Traffic congestion monitoring is a long-term concern in urban areas. However, due to the complex structure of urban road networks and large amounts of traffic data, it is necessary to find an efficient way to identify ...
Freeway Work-Zone Crash Analysis and Risk Identification Using Multiple and Conditional Logistic Regression
Publisher: American Society of Civil Engineers
Abstract: Work-zone safety continues to be a priority and a concern for the Federal Highway Association as well as most state departments of transportation. The main objective of this study is to uncover work-zone freeway crash ...
