Network design for integrated vehicle-sharing and public transportation service
… sharing stations strongly influence the level of travel time savings achieved by the users of the system. Our goal, then, is to select station locations so as to maximize the connectivity with the public transportation system, increase the accessibility to the urban area, reduce travel times, …

Integration of the Transportation Systems Analysis Model for the Small Aircraft Transportation System
Standalone computer modules for county to county travel demand forecasting have been integrated. The Trip Generation, Trip Distribution and Mode Choice modules have been unified under one Graphical User Interface (GUI). The outputs are automatically mapped using Geographic Information Systems (GIS) …

Accessibility of Bay Area Rail Transit Stations: An Evaluation of Opportunities for Transit Oriented Development
… as it is fair to point out issues about auto travel, so too is it fair to see how transit performs at meeting certain goals. This paper examines the important characteristic of accessibility afforded to travelers. This is quantified through the calculation of accessibility indexes for …

Economic impacts of the urban ring : a spatial analysis
… neighborhood-to-neighborhood changes in travel time. I use the proposed Urban Ring in the Greater Boston Area as my case study, and origin-destination (O-D) data for metropolitan Boston to identify current journey-to-work commuting patterns. However, the existing set of ridership data …

Evaluating the Transit Signal Priority Impacts along the U.S. 1 Corridor in Northern Verginia
… Overall, improvements of up to 4% for transit travel time savings and 5-13% reduction in control delay for transit vehicles were observed. Considering all side street traffic, the total increase in maximum queue length might be up to 1.23%. Future research possibilities proposed include the …

Optimal adaptive routing and traffic assignment in stochastic time-dependent networks
A stochastic time-dependent (STD) network is defined by treating all link travel times at all time periods as random variables, with possible time-wise and link-wise stochastic dependency. A routing policy is a decision rule which specifies what node to take next out of the current node based on …

Urban transportation systems policy analysis
… of a hypothetical region which evolves with time. The urban development process is represented by the integration of land use, property market, job market, population, and transportation infrastructure. The interactions within each subsystem and between them are studied through scenario …

Assessment framework for wireless V2V communication-based ITS applications
… application. The application shows gains in travel time savings and a smoother traffic flow as a result of the green light prediction. Higher improvements across penetration rates were observed at high demand levels. The incremental impact of the application on traffic performance tapers off …

A Framework and Analytical Methods for Evaluation of Preferential Treatment for Emergency and Transit Vehicles at Signalized Intersections
… emergency vehicle crash potential and response times. Transit priority employs the same technologies with signal control strategies seeking to reduce travel time and travel time variability. Where both preemption and transit technologies are deployed, operational strategies deconflict …

Transit Priority Measures at Unsignalized Intersections
… of effectiveness related to vehicle delay and travel time for both transit and general traffic. A simplistic benefit-cost analysis was conducted to assess the economic feasibility of the proposed solutions at each intersection. The results indicate that the effectiveness of the proposed …

Understanding Bus Operations Using High-Resolution Vehicle Location Data
… a methodology is proposed to convert the raw, timestamped coordinate data into a continuous and smooth vehicle trajectory function of each bus trip. A case study using historical heartbeat data collected from a real-world bus trip is presented to showcase how a complete trajectory combined with …

Urban Spatial Structure and Household Travel Time
… of the cited harms of sprawl is the alleged travel time burden that it imposes on its residents. Previous research has tested the relationship between the sprawl of business activity and travel times by examining only its effects on commuting times and has concluded that people do not …

Real-time ridesharing : exploring the opportunities and challenges of designing a technology-based rideshare trial for the MIT community
… scheme, drivers and passengers achieve cost savings, they potentially achieve travel time savings, and they benefit from increased travel options. Employers can reduce expensive parking construction or leasing, and benefit from higher worker productivity. Society benefits from congestion …

Piloting an open-source Transport Justice Tool for Southern Africa
… social exclusion in favour of existing travel patterns. The monetary valuation of travel time savings (biased towards projects that serve higher income earners), thus generates more overall benefits and focus of alleviating network congestion. Typically, the general distributive …

Global Demand Model to Estimate Supersonic Commercial Services
… develop a model capable of predicting future air travel demand for supersonic vehicles. The model can predict future supersonic commercial services and allows aircraft designers from NASA to optimize aircraft performance and characteristics by maximizing the potential air travel demand. The final …

Field Evaluation of the Eco-Cooperative Adaptive Cruise Control in the Vicinity of Signalized Intersections
… flow of vehicles by allocating right-of-way in a timely manner for different users of the intersection. Traffic signals are therefore installed at an intersection to improve overall safety and to decrease vehicular average delay. However, the variation of driving speed in response to these signals …

Emotional Agents: Modeling Travel Satisfaction, Affinity, and Travel Demand Using a Smartphone Travel Survey
This dissertation seeks to understand travel satisfaction, travel affinity, and other psychological factors in relation to travel demand, such as the desire for trip making, willingness to spend time traveling, and choice of travel mode. The research was based on the Mood State in Transport …
