Grid Mapping for Road Network Abstraction and Traffic Congestion Identification Based on Probe Vehicle Data
(ASCE, 5/1/2021)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 ... -
Spatial Multiresolution Analysis Approach to Identify Crash Hotspots and Estimate Crash Risk
(ASCE, 5/1/2021)In this paper, we evaluate the performance of a spatial multiresolution analysis (SMA) method, that behaves like a variable bandwidth kernel density estimation (KDE) method, for hazardous road segments identification (HRSI) ... -
Waiting Decision Behavior of Commuters for Bus Transits Based on Prospect Theory
(ASCE, 4/1/2021)Aiming to analyze the waiting decision behavior of commuters for bus transits at a bus station of departure during morning peak hours, this paper builds a bus-waiting decision model based on the prospect theory, with ... -
Modeling and Simulation of Traffic Flow Considering Driver Perception Error Effect
(ASCE, 4/1/2021)Driver’s perception error plays a significant role in determining the dynamical properties of a platoon of vehicles driving on a straight road. Therefore, we attempt to understand the role of driver’s perception errors for ... -
Optimization Method of Subway Timetables for Regenerative Braking Energy Utilization
(ASCE, 5/1/2021)Reducing the energy consumption of trains plays an important role in sustainable development of the subway system. When timetables are generated mainly considering passenger satisfaction, there are still some margins to ... -
Mobility Assessment of Pedestrian and Bicycle Treatments at Complex Continuous Flow Intersections
(ASCE, 5/1/2021)This study evaluated the mobility performance of pedestrian-bicycle crossing alternatives at continuous flow intersections (CFIs). CFI crossing types were compared with a standard intersection designed to provide an ... -
Maximizing Ridership through Integrated Bus Service Considering Travel Demand Elasticity with Genetic Algorithm
(ASCE, 4/1/2021)Developing efficient operational strategies to improve service quality of bus transit, such as reducing travel time, can stimulate ridership. A mathematical model is formulated to optimize integrated bus service which ... -
Trajectory-Based Signal Control in Mixed Connected Vehicle Environments
(ASCE, 5/1/2021)The emerging connected vehicle (CV) technology has introduced the opportunity to improve traditional traffic signal operation. Real-time vehicle trajectory information (location, speed, and heading) from CV technology can ... -
Method for Modeling Lane-Based Driving Discipline of Drivers on Divided Multilane Urban Roads
(ASCE, 4/1/2021)Lane-based driving (lane-keeping) problems generally prevail in undeveloped and developing countries, where drivers’ lane-keeping behaviors are fairly weak for reasons such as poor surface conditions, undisciplined driving, ... -
Development of a Progression-Based Signal-Timing Strategy for Continuous-Flow Intersections
(ASCE, 3/1/2021)Because continuous-flow intersections (CFIs) are a relatively new intersection design, there are few existing guidelines for designing signal timings for CFIs. An appropriate signal-timing plan will maximize the capacity ... -
Estimating Permitted Left-Turn Capacities with Nonstrict Priority Crossing Maneuvers
(ASCE, 3/1/2021)Based on the fact that there are nonstrict priority left-turning maneuvers at signalized intersections with a permitted phase in some countries, this study proposes a left-turn unit-based approach to estimating permitted ... -
Developing Level-of-Service Criteria for Two-Lane Rural Roads with Grades under Mixed Traffic Conditions
(ASCE, 5/1/2021)Traffic operations on two-lane rural roads differ substantially from those on divided carriageways due to vehicular interactions between traffic flows in the opposite directions. With the presence of grades and mixed ... -
Improving Short-Term Travel Speed Prediction with High-Resolution Spatial and Temporal Rainfall Data
(ASCE, 3/1/2021)Heavy rainfall events are becoming more common in many areas with escalating climate change, and these events can considerably affect travel speed and road safety. It is critical to understand when and how rainfall events ... -
Optimizing Transit Equity and Accessibility of the City of Charlotte, North Carolina, by Integrating Transit Gap Index, a General Transit Feed Specification Data-Relevant Performance Metric
(ASCE, 4/1/2021)Public transit is a critical component of transportation planning. One important task is to optimize the public transit service for people by improving current service or having new investments. Under such circumstances, ... -
Modeling Lane-Changing Behavior of Vehicles at Merge Section under Mixed Traffic Conditions
(ASCE, 4/1/2021)The lane-changing behavior of different types of vehicles at the merging section of an urban road is assessed by using a new lane-changing model proposed in the current work. The lane-changing model known as MOBIL (minimizing ... -
Traffic Density versus Rear-End Crash Risk on Freeways: Empirical Model, Mechanism Model, and Transfer to Automated Vehicles
