A “Virtual DMS” method has been created for presenting travel time information to callers of
the North Carolina 511 traveler information telephone service (NC 511). When travel time
information is presented to drivers on Dynamic Message Signs (DMS), the travel times
reported are measured from the physical DMS to a downstream location, such as a cross
street or interchange. As such, the traveler’s location and direction of travel are fixed. This
presentation format is much different than traditional 511 travel time dissemination where the
caller’s location and direction of travel is not only variable but the caller could be calling
from, or could be interested in, any roadway. North Carolina combined the best of both DMS
and traditional 511 travel time presentation, providing callers their travel times to
downstream exits based on their current location and travel direction; termed “Virtual DMS”.

There have been many attempts to implement dynamic ridesharing projects over the
past 15 years, most with very limited success.  The Avego Project at University
College Cork (UCC), in Ireland, provides greater potential by leveraging the advent
of location intelligent consumer mobile phones to provide a marketplace for drivers to
offer their empty seats to riders in real time.  By pricing seats based on mileage,
drivers are incentivized to carpool, and passengers are provided an affordable
transportation option.  Based on preliminary results from UCC, as well as evidence
from past dynamic ridesharing projects, this paper presents 5 critical success factors
for the successful design and implementation of a community-based dynamic
ridesharing project.

Travel time data and its dissemination to the traveling public has been implemented in the latest software release for Maryland’s CHART ATMS in December 2009.  A particular challenge for the CHART system was that the existing speed detector system lacked sufficient density to reliably calculate travel times along most of the state’s highway network. The solution was to utilize travel time data from a subscription service (INRIX[RM] being the chosen vendor).  This paper provides an overview on how the INRIX speed data is collected into the CHART system; how routes are defined; how the travel times are calculated per defined route; how administrators and operators manage the data and design messages; and how the travel times are displayed to the travelling public.

This paper describes the application of systems engineering (SE) to a major innovative
transportation project in the San Francisco Bay Area, the Interstate 80 (I-80) Integrated
Corridor Mobility (ICM) Project. In addition to being one of the first applications of Active
Traffic Management (ATM) to a freeway corridor in the U.S.A., it is also one of the first
detailed applications of formal SE processes to a major highway traffic management project
in the U.S.A.

The United Kingdom has deployed innovative strategies as part of their ITS program. These
strategies include active traffic management, congestion pricing, multimodal traveler information
web sites, integrated demand management, etc. The purpose of this paper is to review the best
practices and lessons learned from their experiences for possible application in the United States.
