RISEffects of Regulation on Highway Pricing and Capacity Choice of a Build-Operate-Transfer Scheme
Publisher: American Society of Civil Engineers
Abstract: The build-operate-transfer (BOT) scheme is being used increasingly by governments in their drive to privatize major public transportation projects. In a BOT scheme, the main objective for the private investors in determining ...
Assessing the Transportation Needs of Low-Mobility Individuals: Case Study of a Small Urban Community in Utah
Publisher: American Society of Civil Engineers
Abstract: Older adults, low-income individuals, and individuals with disabilities are generally considered “low-mobility” individuals, having less access to transportation options and often marginalized in the social environment of ...
Improved Partial Linearization Algorithm for Solving the Combined Travel-Destination-Mode-Route Choice Problem
Publisher: American Society of Civil Engineers
Abstract: Combined travel demand models (CTDM) that integrate trip generation, trip distribution, modal split, and traffic assignment have been developed to resolve the inconsistency problem between the level-of-service and flow ...
Faster Frank-Wolfe Traffic Assignment with New Flow Update Scheme
Publisher: American Society of Civil Engineers
Abstract: The most widely used algorithm for solving traffic assignment problems is the Frank-Wolfe (FW) algorithm. Its popularity is attributed to its modest memory requirements and simplicity. However, it is also known that FW ...
L∞ -Norm Path Flow Estimator for Handling Traffic Count Inconsistencies: Formulation and Solution Algorithm
Publisher: American Society of Civil Engineers
Abstract: Path flow estimator (PFE) is a single-level network observer proposed to estimate path flows and origin-destination flows from traffic counts in a transportation network. The PFE model handles the traffic count inconsistency ...
Examining the Quality of Synthetic Origin–Destination Trip Table Estimated by Path Flow Estimator
Publisher: American Society of Civil Engineers
Abstract: Path flow estimator (PFE) is a one-stage network observer proposed in the transportation literature to estimate path flows and path travel times from traffic counts in a transportation network. The estimated path flows can ...
Quality Measures of Origin-Destination Trip Table Estimated from Traffic Counts: Review and New Generalized Demand Scale Measure
Publisher: American Society of Civil Engineers
Abstract: The goals of this paper are to (1) provide a review of the recently developed measures for assessing the quality of origin-destination (O-D) trip tables estimated from traffic counts and (2) propose a new generalized demand ...
Modeling Network Traffic for Planning Applications in a Small Community
Publisher: American Society of Civil Engineers
Abstract: A procedure is developed to model network traffic for planning applications in small and/or medium-sized communities with limited planning resources. The proposed method is based on the theories and assumptions of conventional ...
Key Strategies for Improving Public Transportation Based on Planned Behavior Theory: Case Study in Shanghai, China
Publisher: American Society of Civil Engineers
Abstract: To advance public transportation development, it should be explored from the perspective of behavioral analysis. This paper adopts the theory of planned behavior (TPB) to study public transportation choice behaviors. The ...
Analysis of Walking Speeds Involving Individuals with Disabilities in Different Indoor Walking Environments
Publisher: American Society of Civil Engineers
Abstract: Walking facilities are important infrastructures in communities. These facilities should be designed to accommodate the needs of all types of pedestrians. Unfortunately, existing design guidelines fail to offer adequate ...
