The Virginia Department of Transportation (VDOT) has relied on customer feedback
to assess the effectiveness of its travel information program, including 511Virginia program.
VDOT launched a statewide 511 service in February of 2005, and in 2007, the system was
upgraded with several new services added, largely based on the input of the systems’ regular, as
well as, casual users. VDOT has a long history of collecting and measuring user satisfaction,
going back to the deployment in 2002 of its regional traveler information service covering only
the I-81 corridor.

511 has been a successful traveler information system in the Bay Area since the telephone number was adopted and launched in 2002. Planned and unplanned events in 2007 further evolved 511 from a traveler information resource to a key tool for public outreach to be used for emergency management and response. These events were: 1) the MacArthur Maze freeway collapse, 2) planned Bay Bridge closure over the 2007 Labor Day weekend, and 3) formal 511 participation in a 2007 regional emergency preparedness exercise with Caltrans and the California Highway Patrol. This paper will review each of these events along with specific lessons learned in using 511 as a tool for public outreach during emergencies. The most significant lesson learned was that the public and policymakers who regularly rely on 511 in the Bay Area automatically expected 511 to be a resource in emergencies. Fulfilling such expectations requires considerable investment in specific tools and operational protocols.

Traveler Information Services such as 511 must be easy for the customer to use and
provide useful information. The alternate route information system developed for the
Central Florida area allows motorists to request routes for their origin and destination in
very generic terms such as Downtown and Airport. They are then provided two or three
routes and travel times for those routes based upon a real-time traffic network. Since
some of the alternate routes contain toll roads, a motorist is able to choose a toll/nontolled
route based upon the travel time.

This thesis introduce a methodology for calculating OD flow of bus stops
based on the data of intelligent card of public transit. First, the date for deducing OD
flow of bus stops and the process of data preparing are expatiated, then analyzing
the characteristics of intelligent card of Beijing public transit, with the data and
characteristics all the possible interchange route-pairs, interchange stops and
interchange directions can be estimated. Identifying number of transfers for each
route-pairs, based on the data of intelligent card. Finally, the methodology of
calculating the OD flow of bus stops of the whole Beijing is introduced.
