Expected Benefits
The 14 electric buses will displace more than 88,900 gallons of diesel per year, and eliminate more than 243,980 pounds of CO2 emissions annually.
In addition to the…
Findings
Under baseline, free-flow conditions, 81.09 percent of trips are completed fastest by the AMoD service, 1.25 percent of trips are completed fastest by mass transit, and 17.66 percent of…
Car2go is currently the largest carsharing operator in the world, with a presence in nine countries and nearly 30 cities. It operates as a one-way instant access carsharing system within a pre-…
This case study of a no-notice evacuation examined the impact of allowing transit signal priority on the evacuation clearance time of transit vehicles and personal vehicles.
METHODOLOGY
The study…
FINDINGS
The evaluation quantified the reduction in the type of side collisions that SODS could prevent. The performance of SODS in identifying side objects was limited to objects located toward the…
District of Columbia Site Case StudyIn 2006, the District of Columbia Department of Transportation (DDOT) deployed an ITS work zone system on I-295 during construction of approximately seven miles of…
Washington D.C. was one of the 12 agencies that responded to the second stage survey on fare payment integration practices and was selected for case study evaluation.RESULTSAt the end of June 2004,…

RESULTSThe analysis showed that the simulated commuter receiving route-specific travel time information typically made more effective route and trip timing decisions than the simulated user of…
RESULTSA dollar valued disutility framework was used to determine the cost value of delay, early arrivals, and late arrivals. By applying this utility function to all trips, it was found that…
RESULTSOverall, regular users of the pre-trip Advanced Traveler Information Service (ATIS) benefited significantly by reducing the frequency of early and late arrivals by 56 percent and 52 percent…
This study used the Mitretek Systems HOWLATE method (Heuristic On-Line Web-Linked Arrival Time Estimator) to quantify the potential benefits of implementing Advanced Traveler Information Services (…
A ramp roll-over warning system was installed at three curved exit ramps on the beltway around Washington, DC in 1993. On-site sensors and computers detected truck speeds, weight, and height…
