Commercial Operations

Special event planning requires coordination and consultation with many from the local
community. Special emphasis needs to be placed on commercial vehicles and freight movement
to and from the special event to assure timely delivery and as little disruption of traffic as
possible. However, in this planning process many times the most obvious of coordination is
sometimes forgotten that being commercial vehicle through traffic and the movement of freight both by large commercial vehicles and local delivery during these events. This failure has a direct impact on the local economy and business in general and the statewide economic stimulus that freight provides.
The use of technologies such as DMS signs, CB Wizards and 511 can assist in letting this vital
group know of preplanned detour routes and times when freight flow may be severely impacted allowing them to plan for alternative routes or delivery times. This paper will provide
information on how to reach out to those areas and the best practices used in these events.

Southwest Research Institute® (SwRI®) was responsible for developing and integrating the
variable pricing element into the SunGuide Advanced Traffic Management System (ATMS)
application used by the Florida Department of Transportation (FDOT). The variable element
was used on the I-95 Express Project which spans a total of 21 miles when completed. 95
Express is an innovative, lower-cost alternative to traditional highway construction that offers
a variety of options for avoiding congestion. A variable-priced toll that adjusts to congestion
levels encourages travel in less heavily traveled periods. It also offers a toll-free option for
those who choose to travel in registered carpools.

The National Transportation Communications for ITS Protocol (NTCIP) standards
have been in existence for over 10 years. Early deployments of NTCIP had many issues as
deployers had difficulties getting their systems operational. NTCIP is now widely deployed and
accepted across the country as the communications protocol of choice for the transportation
industry. This paper is written to agencies and consultants providing an up-to-date, accurate and
concise primer on NTCIP center-to-field communications. It describes NTCIP in an easy to
understand fashion through a series of questions: "Why NTCIP?", "How does NTCIP work?",
"How is NTCIP specified?", "How is NTCIP tested?" and "What are the lessons learned?" The
specification of NTCIP is described in a unique step by step fashion including a flow chart to
help users identify the NTCIP profiles standards they will need. The paper also introduces the
new NTCIP Guide Version 4 that was just recently accepted as a Recommended Information
Report by the NTCIP Joint Committee.

An Arterial Travel Time solution has been developed that provides high vehicle match rates
while maintaining complete user privacy. The system re-identifies the magnetic signatures
from vehicles as they pass over in-pavement sensor arrays at different points of interest. The
system outputs the complete and accurate distribution of travel times for the arterial, even in
the presence of signalized intersections.
This paper presents the theory of application of this Arterial Travel Time solution, a review
as to the importance of vehicle match rates, the ground truth methodology used to verify
performance and a review of its deployment by San Diego Association of Governments
(SANDAG) in Chula Vista, California.

Active Traffic Management (ATM) integrates the use of numerous traffic management and
Intelligent Transportation Systems (ITS) tools to manage traffic flow as a means to mitigate
traffic congestion under recurring and non-recurring conditions. These tools may include
dynamic lane assignment, variable speed limits, part-time utilization of shoulders as traffic
lanes, queue warning and contra-flow operations. ATM has most frequently been deployed in
Europe, as well as some bridges and tunnels in the U.S., but is increasingly being investigated
for U.S. freeway applications, both for permanent and work zone applications. Benefits
include reductions in accidents along with reduction in congestion due to optimization of
traffic flow. This paper provides a current overview of ATM applications in the U.S. and
abroad, as well as an overview of suggested next steps in ATM deployment.
