Optimal Adaptive Departure Time Choices With Real-Time Traveler Information Considering Arrival Reliability, Xuan Lu

Masters Theses 1911 - February 2014

When faced with an uncertain network, travelers adjust departure time as well as route choices in response to real-time traveler information. Previous studies on algorithm design focus on adaptive route choices and cannot model adaptive departure time choices (DTC). In this thesis, the optimal adaptive departure time and route choice problem in a stochastic time-dependent network is studied. Travelers are assumed to minimize expected generalized cost which is the sum of expected travel cost and arrival delay costs. The uncertain network is modeled by jointly distributed random travel time variables for all links at all time periods. Real-time traveler information …

Computer-Assisted Emergency Evacuation Planning Using Transcad: Case Studies In Western Massachusetts, Steven P. Andrews

Masters Theses 1911 - February 2014

Disasters, ranging from manmade events to natural occurrences, can happen anywhere on the planet, and their consequences can range from economic loss to catastrophic loss of life. Determining how the transportation system fares in the face of these disasters is important so that proper planning can take place before, rather than after, an event has happened. Modeling the transportation system gives operators the ability to discover bottlenecks, to determine the possible benefit of using lane reversals, and to find out the influence of evacuation speed on system efficiency. Models have already been created that are able to model some of …

Developing An Evaluation Approach To Assess Large Scale Its Infrastructure Improvements: I-91 Project, Melissa Paciulli

Masters Theses 1911 - February 2014

Intelligent Transportation Systems (ITS) can include multiple technologies and applications combined to improve the overall efficiency and effectiveness of the transportation system or network. These applications are deployed with the anticipation that the desired project goals and objectives established by multiple stakeholders will be achieved. Once a system is deployed, the project goals and objectives should be evaluated. The evaluation can provide both quantitative and qualitative feedback to assess the impacts associated with the investment in building, designing and implementing these systems.

This research includes a methodology to evaluate large scale ITS infrastructure projects using the Interstate 91 (I-91) ITS …
