Modeling Framework to Identify an Affected Area for Developing Traffic Management Strategies
(American Society of Civil Engineers, 2018)When a traffic incident occurs, congestion starts to disseminate around the incident location. Considering a suitable area to assess the impact of incidents and develop traffic network prediction models for evaluating ... -
Multiconstrained Timetable Optimization and Performance Evaluation in the Presence of Travel Time Noise
(American Society of Civil Engineers, 2018)This work addresses the problem of bus timetabling under multiple operational constraints with the objective of minimizing the waiting time variations of passengers at stops. It places specific emphasis on practical ... -
Modeling External Trips: Review of Past Studies and Directions for Way Forward
(American Society of Civil Engineers, 2018)Proper estimation of external trips is vital because it may affect the model validation results when compared with traffic counts. In practice, external trips are divided into three categories: external–external (EE), ... -
New Model for the Railway Network Design Problem
(American Society of Civil Engineers, 2018)In this paper, mixed-integer programming for the railway network design problem with a new objective function is proposed. The model considers development projects (new line construction and existing line improvement), ... -
Comparison of Speed Control Bumps and Humps according to Whole-Body Vibration Exposure
(American Society of Civil Engineers, 2018)One of the easiest and most efficient ways to control vehicle speeds is to create undulations perpendicular to the axis of the road. The types of undulations especially used for speed management on urban road networks are ... -
Evaluating Measures of Effectiveness for Quality of Service Estimation on Two-Lane Rural Highways
(American Society of Civil Engineers, 2018)The level of service on two-lane rural highways can be estimated using the percent time spent following (PTSF) and average travel speed (ATS). Because PTSF cannot be directly observed in the field, the literature suggests ... -
Modeling Highway Performance under Various Short-Term Work Zone Configurations
(American Society of Civil Engineers, 2018)Federal rules mandate state departments of transportation and metropolitan planning organizations to measure and report on the performance of highways within their jurisdictions. Those rules support an initiative for ... -
Shockwave-Based Queue Length Estimation Method for Presignals for Bus Priority
(American Society of Civil Engineers, 2018)This paper presents a shockwave-based method for estimating queue length associated with presignals for bus priority. Both queue length at presignals and main signals are estimated by the proposed method. In this study, ... -
Prediction of Track Deterioration Using Maintenance Data and Machine Learning Schemes
(American Society of Civil Engineers, 2018)The maintenance and renewal of ballasted track can be optimized in terms of time and cost if a proper statistical model of track deterioration is derived from previous maintenance history and measurement data. In this ... -
Overtaking Disturbance on a Moped-Bicycle-Shared Bicycle Path and Corresponding New Bicycle Path Design Principles
(American Society of Civil Engineers, 2018)In China, the overtaking disturbance caused by mopeds on a shared bicycle path is one of the most important factors that could significantly affect a cyclist’s riding safety. However, bicycle paths are currently designed ... -
Estimation of U-Turn Capacity at Median Openings
(American Society of Civil Engineers, 2018)Median openings are provided in multilane divided roads to enable U-turns. The atypical conditions prevailing in India motivated this study for the development of a methodology for the proper computation of the capacity ... -
Sustainable and Cost-Effective Pavement Preservation Method: Micromilling and Thin Overlay
(American Society of Civil Engineers, 2018)To respond to funding shortages and sustainably preserve their aged pavements, transportation agencies are forced to go beyond conventional thinking to develop innovative, cost-effective pavement preservation methods to ... -
Modeling Duration of Lateral Shifts in Mixed Traffic Conditions
(American Society of Civil Engineers, 2018)Traffic on urban roads in developing countries is characterized by wide mix of vehicles with loose lane discipline, which results in parallel movement of vehicles in the same lane. Hence, vehicles not only interact ... -
Heterogeneity in Valuation of Travel Time Reliability and In-Vehicle Crowding for Mode Choices in Multimodal Networks
(American Society of Civil Engineers, 2018)To support scientific planning and management of transportation systems, this paper carries out comprehensive stated preference (SP) surveys to investigate commuters’ mode choice behavior in multimodal networks. Efficient ... -
Modeling Automobile Interference due to Midblock Pedestrian Activity on Urban Street Segments
(American Society of Civil Engineers, 2018)The 2010 highway capacity manual (HCM) provides an approach to estimate the mutual between pedestrians and automobiles at signalized intersections. However, the manual provides little guidance for capturing the interactions ... -
Contributing Factors to Run-Off-Road Crashes Involving Large Trucks under Lighted and Dark Conditions
(American Society of Civil Engineers, 2018)Previous studies have examined the relationships between run-off-road (ROR) crashes and the contributing factors; however, the impact of lighting conditions has been insufficiently addressed. As a result, the objective of ... -
Evaluation of Vehicle Detection Systems for Traffic Signal Operations
(American Society of Civil Engineers, 2018)Typical vehicle detection systems used in traffic signal operations are composed of inductive loop detectors. Because of costs, installation challenges, and operation and maintenance issues, many alternative nonintrusive ... -
Methodology for Control Delay Estimation Using New Algorithm for Critical Points Identification
(American Society of Civil Engineers, 2018)Control delay, as a primary indicator of signalized intersection performance, is commonly estimated using analytical models due to difficulty of field measurements. This paper presents a new methodology for control delay ... -
