Quantifying Significance of Young Traveler Characteristics in Travel Mode Choices Impacted by E-Hailing Services
(ASCE, 2020)Traditional travel modes have been slowly losing their market share to e-hailing services, especially among younger generations. This paper examines characteristics of young travelers’ travel mode choice, with various ... -
Optimization of Traffic Signal Offsets with High Resolution Event Data
(ASCE, 2020)Recently, high-resolution data has emerged as an economical means of obtaining detailed information about signal operations. This has enabled the development of metrics to examine progression, such as cyclic flow profiles ... -
Passenger Travel Behavior Analysis under Unplanned Metro Service Disruption: Using Stated Preference Data in Guangzhou, China
(ASCE, 2020)Passengers may change their original travel plans when unplanned metro service disruption occurs, which causes excessive crowding and endangers the safety of passengers. However, it’s not clear about the mechanism of ... -
Effect of Video Detection System Layout under Covering and Differentiating Route Flow Principles
(ASCE, 2020)Video detection system (VDS) sensors play an important role in monitoring traffic flows. Because of limited numbers of camera installations, there is a dilemma in positioning camera sensors between the system’s coverage ... -
Integrated Approach to Vehicle Scheduling and Bus Timetabling for an Electric Bus Line
(ASCE, 2020)Timetable and vehicle scheduling are important for transit operations. Electric buses are more environmentally friendly compared with conventional buses, and have been developing rapidly and may replace conventional buses ... -
Optimal Design of Feeder-Bus Network with Split Delivery
(ASCE, 2020)Feeder-bus networks between urban rail transit systems and bus stops are inefficient in terms of the cost incurred by passengers, the time taken to reach the destination, and the number and frequency of feeder buses. To ... -
Analysis of Subway Station Distribution Capacity Based on Automatic Fare Collection Data of Nanjing Metro
(ASCE, 2020)To realize an early warning system for crowded subway passenger flow, a new calculation method of subway station distribution capacity (SSDC) in real time is proposed. First, a new concept of SSDC is defined according to ... -
Railroad Track Geometric Degradation Analysis: A BNSF Case Study
(ASCE, 2020)Planning and optimizing maintenance actions for rail failures are possible through understanding rail behaviors, which can be captured by statistical models. In this study, a degradation analysis of railroad tracks is ... -
Continuous Approximation of Deficit Functions for Fleet Size Calculation
(ASCE, 2020)It is a fundamental and important task to determine the minimum fleet size required for a public transit (PT) system because the fleet cost is a major operating expense experienced by PT agencies. More importantly, the ... -
Comprehensive Approach to Transfer Synchronization in Public Transit
(ASCE, 2020)The dynamic and uncertain characters of traffic often make bus schedules erratic; therefore, planned synchronized public transit transfers do not always materialize. This research aims at reducing the operational deviation ... -
Assessment of Methodological Alternatives for Modeling the Spatiotemporal Crossing Compliance of Pedestrians at Signalized Midblock Crosswalks
(ASCE, 2020)At the midblock crosswalks with either Pedestrian Hybrid Beacons (PHBs) or Traffic Control Signals (TCSs), pedestrians’ crossing compliance can be considered in terms of the space (crossing location with respect to stripes) ... -
Lane-Based Queue Length Estimation in Heterogeneous Traffic Flow Consisting of Cars and Buses
(ASCE, 2020)Queue length is the most important traffic evaluation index used for traffic signal control at signalized intersections. Most previous studies focused on estimating the queue length in homogeneous traffic flow, but they ... -
All-Red Clearance Intervals for Use in the Left-Turn Application of Flashing Yellow Arrows
(ASCE, 2020)In recent years, agencies across the United States have embraced the implementation of the flashing yellow arrow (FYA) for permissive left turns. Previous research determined that the FYA indication communicated the presence ... -
Effect of Autonomous Vehicles on Performance of Signalized Intersections
(ASCE, 2020)In this study, changes in traffic flow characteristics were examined in a mixed system consisting of human drivers and autonomous vehicles. In the study, it is accepted that in the environment where the autonomous vehicles ... -
Critical Assessment of Microscopic Simulation Models for Simulating Turbulence around Motorway Ramps
(ASCE, 2020)In current motorway design practice, microscopic simulation is used to assess the traffic safety and capacity implications of design variants. Many different simulation packages are available, and many researchers have ... -
Integrated Empirical Analysis of the Effect of Variable Message Sign on Driver Route Choice Behavior
(ASCE, 2020)This paper investigated the effect of a variable message sign (VMS) on drivers’ route choice behavior through a questionnaire survey and field-observed route choice data. A logistic model was developed based on the ... -
Fusing Freight Analysis Framework and Transearch Data: Econometric Data Fusion Approach with Application to Florida
(ASCE, 2020)A major hurdle in freight demand modeling has always been the lack of adequate data on freight movements for different industry sectors for planning applications. Both Freight Analysis Framework (FAF) and Transearch (TS) ... -
