Algorithms for routing vehicles and their application to the paratransit vehicle scheduling problem

Description: "As the demand for paratransit services increases, there is a constant pressure to maintain the quality of service provided to the customers while minimizing the cost of operation: this is especially important as the availability of public funding for paratransit services has been on the decline. Key tasks in accomplishing this objective are efficiently allocating vehicles to service trips and adjusting the schedules of vehicles dynamically in response to calls received by the service providers from the customers on the day of the service."

Enhancement and Outreach for the Active Management Screening Tool

Description: This document reports on the enhancement of and outreach for an active management screening tool. The purpose of the Active Management Screening Tool (AMST) is to help agencies better assess the potential of active management strategies for their region within the congestion management process (CMP). It is structured to provide beneficial information and guidance related to active management strategies in all areas and levels of transportation planning." (Abstract).

Multi-vehicle mobility allowance shuttle transit (MAST) system : an analytical model to select the fleet size and a scheduling heuristic

Description: "This report discusses the mobility allowance shuttle transit (MAST) system which is a hybrid transit system in which vehicles are allowed to deviate from a fixed rout to serve flexible demand. The mixed interfere programming (MIP) formulation analyzed the impacts of time headways between consecutive transit vehicles on the performance of a two-vehicle MAST system. An analytical framework is then developed to model the performance of both one-vehicle and two-vehicle MAST systems, which is used to identify the critical demand level at which an increase of the fleet size from one to two vehicles would be appropriate. From this research an insertion heuristic for a multi-vehicle MAST system was developed."

Refining a Methodology for Determining the Economic Impacts of Transportation Improvements

Description: This document discusses the methodology for determining the economic impacts of transportation improvements by the Texas Transportation Institute. "This project examined the current and historical economic impact assessment programs utilized by four state departments of transportation. Researchers evaluated these programs based on three outcomes: increased business and industry competitiveness, strengthened long-term regional and local economies, and enhanced household well-being. Researchers found that promoting transparency and flexibility and involving as many stakeholders as possible were key elements to economic program success. Based on these successful program elements, TTI professionals developed a new economic determination method to incorporate into the existing Transportation Revenue Estimation and Needs Determination System (TRENDS). The results from this study were also used to educate the public on the impacts transportation improvements, or lack of improvements, have on communities." (Abstract).

Use of performance measurement to include air quality and energy into mileage-based user fees

Description: "This research project is aimed at establishing a framework for levying MBUFs designed to achieve various air quality improvement policy objectives. This research presents the first step toward a pricing framework based on the concept of performance measurement that systematically defines and incorporates potential air quality goals. The process of developing the proposed framework included defining the interactive role of user fees and pricing in roadway transportation operations and identifying air quality performance measures for determining the appropriate vehicle mileage fee price."
