The Minnesota Department of Transportation was awarded a grant from the United States Department
of Transportation to conduct field operational test that will demonstrate effective voice and data
interfaces between private sector call centers, or telematic service providers (TSP), and public safety
answering points (PSAPS). The field operational test’s objectives are to demonstrate deliver voice
communication from the TSP call center directly to the appropriate PSAP based on the location of the
vehicle. Additionally, this project has demonstrated a viable approach for data transfer between the
TSP call center and the responder community.

The Minnesota Department of Transportation embarked upon the TIGER (Traveler
Information Guidance and Emergency Routing) Project in the summer of 2003. The
geographical scope of this project is the transportation corridor between the Minneapolis/St.
2
Paul metropolitan area (pop. 2.9 million) and St. Cloud (pop. 90,000), which is located 60
miles northwest. The TIGER project is uniquely challenging in many ways. Not the least
of which is the challenge of providing a reliable and cost-effective communication network to
field devices with varying bandwidth requirements and in areas with limited existing
infrastructure. This paper summarizes Mn/DOT’s approach, which employs a fiber optic
backbone as well as high bandwidth and low bandwidth wireless communication. This
paper provides an overview and lessons learned from the communication planning, design
and deployment efforts to date.

This paper presents the methodology for Mobile IP Trial Evaluation at California’s Capital
Corridor Inter-City Rail project [1] [2]. The goal of the project is to pursue Pilot
Demonstrations to provide Wireless LAN, High speed Internet connectivity and Info-centric
Services on trains and this started with an initial co-operation in California’s Capitol
Corridor’s AMTRAK service subsidized by California Department of Transportation
(Caltrans) managed by the Capitol Corridor Joint Powers Authority with similar efforts at
SNCF in France and co-operation between French technology center of excellence INRETS,
GLOCOL USA and the University of California (Berkeley). The Trains Connected
Partnership Project Work Group was set up to focus on emerging standards, technologies and
evaluations which have received interest from various Rail Authorities. The focus is to
understand the best ways to incorporate satellite communication, Wi-Fi, Wi-Max, Mobile IP
and various promising technologies into broader applications such as passenger service, train
operations, safety and security. This paper reports seamless roaming simulations over
different systems using Mobile IP.

AAA/CAA clubs are deploying advanced communications hardware and software for the
purpose of improving road service to its members. Low-cost wireless data
communications continues to grow in strategic importance to AAA road service as a means
to:

• accelerate the information process permitting the service vehicles to arrive at the

breakdown location faster and handle more calls per day.

• enable electronic payment processing and other transactions at roadside.

• capture information from the members, their vehicles, and the service provider

which is useful for AAA planning and real-time management of the service fleets
and call center personnel.

• accurately transmit information and warehouse it in databases.

• incorporate service vehicle location into decision making (see AAA’s Wireless

Data and Intelligent Fleet Management, ITSWC Madrid 2003).

In this paper, the Stackelberg game theory is applied to optimally coordinate ramp
metering and speed control in order to alleviate congestion on urban freeways. Ramp metering can
prevent a traffic breakdown by adjusting the metering rate. Speed control is to regulate and guide the
traffic flow on the mainline of freeway to achieve stable traffic flow. After the interaction between
variable speed and ramp metering is analyzed, we formulate the ramp metering and variable speed
control as a Stackelberg game and variable speed control is regarded as the leader, ramp metering as
the followers. Within this framework, we propose a Stackelberg game model of ramp metering and
variable speed control. At last, we use a simple network to illustrate our approach and the simulation
results show that this approach is effective.
