Team Michigan: Connecting Vehicles And Partners
This paper provides a overview of Michigan’s unique approach to moving ahead on the vision of
technical and relationship integration and on building a connected vehicle system that meets
shared public and private objectives. The transformation of the automotive industry from
mechanical to electronic engineering is critical to the Michigan economy as the dramatic
reduction in automotive industry jobs has placed Michigan at the forefront of what appears to be
a recession of the U.S. economy. The Michigan economy lost 75,000 jobs in 2007 and appears
to be headed in a similar direction in 2008. Connected vehicle technology development offers
Michigan a growing high-tech industry where Michigan companies have a competitive
advantage. Michigan is also home to the MDOT and other public-sector agencies that have
demonstrated national leadership in connected vehicles. “Team Michigan” is pursuing a strategy
for testing and developing VII providing all the players necessary for further developing vehicle
communication systems that keep drivers connected, save lives, improve mobility, protect the
environment, and employ Michigan residents.

Tampere Region Its - A Multi-Stakeholder Public-Private Network
The City of Tampere in central Finland, Europe, together with neighboring municipalities,
form a region of about 350.000 citizens, from which more than 200.000 citizens live in the
City of Tampere. The region has since the beginning of 1990’s actively developed through
public-private partnerships and co-operation some of the Europe’s leading ITS services for
citizens and private & public organizations. Examples of these advanced services are: GPSpositioning and priority system for buses and emergency vehicles, real-time public transport
information displays at bus stops and main public places, mobile and web based public
transport information for travelers, multi-purpose smart cards for public transport, libraries,
swimming arenas etc, public transport journey planner, journey planner for cyclists, voice
recognition and text message based timetable information, real-time parking place
information, warning system for trucks approaching low bridges, boat/ferry connection
information displays, taxi and demand responsive dispatching systems, real-time traffic
information portal that collects data from floating cars, fixed measurement points and traffic
lights and combines all the traffic data in the city and many more. In the spring 2007 the
different stakeholders; ITS service providers, hardware suppliers, software suppliers,
consultancies, universities and authorities decided to establish an open co-operation network
to promote and co-ordinate the existing and future development and implementation activities
in the City of Tampere and the surrounding region in a more organized and effective manner.
Thus all the development activities could benefit from and support each other and make
Tampere one of the main cities and test-beds in the world in the field of advanced ITS
systems.

Taffic Flow Characteristics In A Mixed Traffic System Consisting Of Acc Vehicles And Manual Vehicles
In this paper, we investigate traffic flow characteristics in a traffic system consisting of a
mixture of adaptive cruise control (ACC) vehicles and manual-controlled (manual) vehicles,
by using a hybrid modeling approach. In the hybrid approach, (i) manual vehicles are
described by a cellular automaton (CA) model, which can reproduce different traffic states
(i.e., f ree flow, synchronized flow, and jam) as well as probabilistic traffic breakdown
phenomenon; (ii) ACC vehicles are simulated by using a car-following model, which removes
artificial velocity fluctuations due to intrinsic randomization in CA model. We have studied
traffic breakdown probability from free flow to congested flow and transition probability from
synchronized flow to jam in the mixed traffic system. The results are compared with that,
where both ACC vehicles and manual vehicles are simulated by CA models. The qualitative
and quantitative differences are indicated.

Successful Application Of Systems Engineering For Complex Statewide ITS Deployments
The Texas Department of Transportation (TxDOT) has been actively involved in Intelligent Transportation Systems (ITS) at a statewide level since 1998. Key to the TxDOT ITS Statewide Development and Integration (SDI) Program has been the concept of develop once and reuse many times. Benefits of the Texas SDI program have extended to the 25 districts in the state which include both metropolitan and rural deployments and several of the largest cities in the United States. ITS applications include traditional traffic management centers as well as border safety inspection facilities. The program has had to deal both with new development and deployment as well as integration into existing deployments with legacy equipment and migration issues. Software has been licensed for use by other state departments of transportation and successfully built upon. Through reciprocal licenses, TxDOT has been able to take advantage of additional capability developed. An overview of the program and its accomplishments will be given.

Statewide Procurement Of Demand-Response Transport Scheduling Systems:
Several states in the U.S. have supported the needs of public transport agencies that provide
demand-response transport (DRT) services by procuring scheduling and dispatching software
on their behalf. The primary impetus for these states to undertake such procurements was
that many of their agencies do not have the resources and expertise that is required for
procuring and deploying such systems. Further, the prospect of selling these systems across
an entire state was expected to increase the competition among the vendors of these products.
The statewide procurements have resulted in agencies within a particular state being able to
purchase and deploy the selected software product. While many benefits have been
experienced by the agencies that have deployed these products, there have been significant
challenges in the procurements, as well as the deployments.
This paper will describe and summarize the results of three statewide procurements of DRT
scheduling and dispatching systems – those in Iowa, Tennessee and Pennsylvania. The
challenges associated with each procurement will be discussed, along with the ways that each
challenge was overcome. Finally, the overall lessons learned from these procurements will
be summarized.
