INNOVATIVE IDEA PROJECTS: ORIGIN-TO-DESTINATION TRAVEL TIME RELIABILITY INFORMATION ON GOOGLE MAP (L15A)
A report that describes a proof-of-concept of a framework for giving drivers travel time reliability predictions. The framework would provide metro-wide network coverage and be integrated into traveler information systems operated by state DOTs or commercial enterprises.
|
This framework offers motorists the possibility of reducing the buffer time necessary to compensate for uncertain events such as accidents. The framework is applicable to any congestion-prone corridor.

INNOVATIVE IDEA PROJECTS: PROXIMITY INFORMATION RESOURCES FOR SPECIAL EVENTS (L15B)
A final report and a mobile application to assist in management and communications during large events. The app provides access to critical information such as first aid, parking, shuttles, recommended driving routes, event program, timetables, and navigation of booths and stages.
|
The ability to measure the size and movement of crowds at large events and to communicate with them is a valuable step forward in emergency management.

INNOVATIVE IDEA PROJECTS: ONLINE TRAFFIC SIMULATION SERVICE FOR HIGHWAY INCIDENT MANAGEMENT (L15C)
This proof-of-concept project will develop: (1) web based capabilities for traffic simulation scenario editing and maintenance; (2) automatic simulation model creation out of real-time traffic measurement data; and (3) a suite of incident scenarios and response strategies and test results from their use on one California freeway. A final report will be completed detailing the conclusions.
|
This product will allow operations planners to not only see how the freeway performed yesterday, or during last week, by looking at historical data, but also immediately recreate traffic behavior in the simulation, and then edit and test “what-if” scenarios.

INNOVATIVE IDEA PROJECTS: URBAN TRAVEL RELIABILITY ANALYSIS WITH CONSUMER GPS DATA (L15D)
The project constructs travel time distributions at both link and route levels, and evaluates the reliability performance of alternative routes between a given origin-destination. A technical report will describe the analytical approach and case study results.
|
This research will have an impact on our understanding of spatial and temporal characteristics of travel time reliability performance by documenting the various reliability indexes for drivers with different risk-taking preferences and analyzing randomly selected origin-destination pairs and time periods.

Staff Responsibility: Inam Jawed (ijawed@nas.edu) and Ralph Hessian
There was considerable value in devoting a portion of the SHRP 2 research program’s resources to the development of innovative ideas. The development of a portfolio of innovative projects was administered in cooperation with the TRB program entitled Innovations Deserving Exploratory Analysis (IDEA). The TRB IDEA program funded two types of projects. Type I projects consisted of the exploration of unproven concepts to demonstrate their validity. Type II projects developed and tested prototypes of proven concepts.
The objective of this project was to elicit from the research community, businesses, and others innovative and practical ideas for improving travel time reliability and to provide initial funding for a portfolio of projects. The hope was to attract a range of ideas to fund with the expectation that one or two, when developed further and implemented, would eventually have a large impact and payoff.
