Simulation-Based Multistage Optimization Model for Railroad Alignment Design and Operations
(ASCE, 2020)In railroads, the vertical alignment design is closely related to the cost of operation because it may affect the required energy consumptions. By considering an innovative vertical alignment design concept such as the ... -
Effects of Variable Speed Limit on Energy Consumption with Autonomous Vehicles on Urban Roads Using Modified Cell-Transmission Model
(ASCE, 2020)Autonomous vehicles create new opportunities for innovative intelligent traffic systems. Variable speed limit (VSL), which is a speed management system that can adjust the speed limit according to traffic conditions or a ... -
Characterizing Traffic-Signal Performance and Corridor Reliability Using Crowd-Sourced Probe Vehicle Trajectories
(ASCE, 2020)Performance measures offer an essential management tool for transportation engineers to make decisions along signalized corridors. Current signal performance strategies assess coordination of a corridor using intersection-level ... -
Online Survey of Driver Comprehension of the Flashing Yellow Arrow for Right-Turn Signal Indications
(ASCE, 2020)This paper presents the results of an online survey of licensed driver comprehension of the right-turn signal displays with a focus on the flashing yellow arrow (FYA) and also including the circular green and red and red ... -
Complete Estimation Approach for Characterizing Passenger Travel Time Distributions at Rail Transit Stations
(ASCE, 2020)Route choice behavior of a rail transit passenger is not directly observable and it may be affected by the route travel time to a large extent. Compared to the on-train time, travel times at stations, including walking ... -
A Case for Feedback Control to Prevent Delay
(ASCE, 2020)This study was motivated by the work of researchers who conducted field experiments on roadways with no bottlenecks. The ring roads are circular roadways where passing was restricted. All drivers who took part in these ... -
Effects of Weather and Calendar Events on Mode-Choice Behaviors for Public Transportation
(ASCE, 2020)Understanding travel behavior decisions is a fundamental aim of transportation planning. However, data from surveys or travel diaries that were traditionally used for travel mode-choice modeling are costly and have certain ... -
Optimizing Freeway Merge Operations under Conventional and Automated Vehicle Traffic
(ASCE, 2020)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 ... -
Parking Permit Management of Morning Commuting Considering Carpooling with Parking Restraint
(ASCE, 2020)This study investigates the efficiency of parking permits in managing morning commuting considering carpooling with parking restraint. First, the morning commuting problem was revisited with and without parking restraint ... -
Consensus Phenomenon and Characteristics of Vehicle Cooperative Driving
(ASCE, 2020)The consensus degree among vehicles is an important index to measure the cooperative driving system. First, this paper establishes a measurement method of the instantaneous consensus of an individual vehicle to evaluate ... -
Using Microsimulation to Estimate Effects of Boarding Conditions on Bus Dwell Time and Schedule Adherence for Passengers with Mobility Limitations
(ASCE, 2020)Both bus dwell time and bus headway adherence are critical to the serviceability of the bus transit system. It is acknowledged that passengers with physical disabilities may greatly impact bus dwell time and bus headway ... -
Look-Ahead Transit Signal Priority Control with Self-Organizing Logic
(ASCE, 2020)In this paper, a model for transit signal priority control is presented. The model is based on an adaptive signal control called self-organizing logic (which evolved from fully actuated control) with advanced features, ... -
Optimization of Actuated Traffic Signal Plans Using a Mesoscopic Traffic Simulation
(ASCE, 2020)Traffic signal plan designs become more complex with developments in the fields of sensing and communication and the introduction of features, such as transit priority or pedestrian actuation. Traffic signal optimization ... -
Measures of Travel Reliability on an Urban Rail Transit Network
(ASCE, 2020)To evaluate the travel reliability of an urban rail transit (URT) in normal operation, three travel reliability indicators are proposed from passengers’ travel. The connectivity reliability, travel time reliability, and ... -
Integrating Bus Priority and Presignal Method at Signalized Intersection: Algorithm Development and Evaluation
(ASCE, 2020)Bus signal priority (BSP) is an effective strategy to enhance the quality of public transit service, but unfortunately, it also deteriorates the performance of general vehicles. However, the tandem intersection with midblock ... -
Modeling Individual Travel Time with Back Propagation Neural Network Approach for Advanced Traveler Information Systems
(ASCE, 2020)The heterogeneous driving behaviors from different travelers are not considered in current advanced traveler information systems (ATIS) such as Google Maps and 511 systems, which leads the systems to generate the same ... -
