Using Geospatial Tools for State-Wide Communications Network Planning
In 2008 Wisconsin Department of Transportation (WisDOT) completed the Traffic Operations Infrastructure Plan (TOIP) study, which identified locations for deployment of ITS devices on a statewide basis. This plan included location, prioritization and cost estimation for the devices themselves, but did not include communications infrastructure to support the deployments.
The Communications Systems Layer (CSL) plan used geo-spatial tools and a rules-based decision making methods to choose from multiple communication options for each site. In addition, the CSL considered connections to a variety of WisDOT centers and partner agencies so that estimates could be created for an overall, statewide plan that provided specific technical recommendations and cost estimates for more than 1,400 individual points representing data users. The initial draft of connections and estimates was completed in only three months, which was only possible through the novel use of data management and analysis tools.

Using FLOW Traffic Management Methods To Significantly Reduce Fuel Consumption Rates And Results
FLOW (Fast Lane On Warning) algorithms manage traffic and reduce fuel consumption rates.
The applications presented here will cover two out of the four types of FLOW management:
open first-encountered approaches, and inter-signal networks where traffic signals are far apart
elative to speed.. The discussion here will include algorithms for safety, emplaced readouts,
mobile readouts, adaptive robotic real time changing capabilities.
Motorists will be able to proceed with their own individual speed assignments ranging from the
afe speed limit to a bit below half that speed depending on how long their particular open right
of way (green segment) is as well as when they arrive at the beginning of a FLOW trap.
These algorithms and associated hardware will significantly decrease fuel expenditures on an
ntersection by intersection basis, and significantly reduce pollution (NOx, particulates, O3, COx
nd so on) on an intersection by intersection basis. The algorithms presented here allow for
vehicles to remain in the high energy state. Comparisons between this high energy state vs.
raffic systems without (where most have to reaccelerate back up to the high energy state) are presented in terms of lesser fuel consumption rates and pollution reduction approximations:
1. For an individual intersection, 2. For the LA area as an example, 3. For the Continental US.

Using Commercial Vehicle Telematics As A Highway Probe Data Source
The purpose of this technical paper is to discuss the project advanced by Calmar Holdings
and Telematics LLC in partnership with the New York State Energy Research and
Development Authority (NYSERDA), the New York State Department of Transportation
(NYSDOT) and the Federal Highway Administration (FHWA) to explore the potential of
using telemetry data as a source of traffic information. These data, already collected by
commercial vehicle operators for fleet management purposes, are being used to determine
traffic and highway conditions for use by transportation agencies. This research and
development effort determined that it is possible to use privately collected and owned real-
time fleet telemetry data to determine highway and traffic throughout the entire highway
network where and when a non trivial population of commercial vehicles are present. In
addition, commercial vehicle telematics holds vast potential for various transportation
applications involving transportation planning, traffic management and highway operations.

User Needs For Co-Operative Infrastructure To Vehicle Communication Systems Focus On Infrastructure
COOPERS, an EC FP6 funded IP deals with Co-operative Systems, enabling the
communication of real time data between infrastructure and vehicle. During the first year of
the project User Needs from Infrastructure Operators and Traffic Control Centres, Traffic
Information Service Providers, and Policy Advisory Organisations were analysed. This paper
shows, that the most interesting services for this target groups are * ) ISA with Infrastructure
Link (speed limit information only, no active control over the car), *) Route Navigation and
Network Information, *) Mayday (as breakdown detection for infrastructure operators) and *)
International Service Handover (not perceived as independent Service).

Use Of Standard Planning Level Data To Develop The Detroit Area
Integrated Corridor Management (ICM) strategies have been proposed as a composition of solutions for improving safety and optimizing vehicular and person throughput along an entire corridor. A portion of I-75 located in southeast Michigan is scheduled for extensive construction and rehabilitation. To prepare for the anticipated loss of capacity on I-75, MDOT performed a study to evaluate ICM solutions that could improve multi-modal throughput on the designated corridor located in Wayne, Oakland, and Macomb Counties. The stakeholder representation included agencies responsible for the roadway networks, transit, and public safety within the designated study area. Facilitated by a transportation consultant, the stakeholders identified corridor needs, assessed the corridor infrastructure, and identified opportunities to improve travel outcomes for users of the corridor through improved inter-agency coordination and the application of technology and traveler information.
