ITS Deployment AssessmentCreated by the Minnesota Department of Transportation (Mn/DOT), in cooperation with other transportation stakeholders. The intent was to assess current programs and future opportunities for deployment of ITS.Focus was on safety and mobility.Two sections. Section 1 provides a “Background and Building a Foundation for Success”. Section 2 builds on Section 1 by providing information on “Future ITS Deployments in Minnesota”. Reflects short, medium, and long-term needs and operational objectives.

ITS Deployment AssessmentThe overriding goal of this project was to develop an assessment in sufficient detail that the assessment could be used to help establish priorities and secure funding for ITS deployment projects that improve safety and mobility.
Toward that goal, two ITS program initiatives were established.Minnesota Guidestar Mobility InitiativeMinnesota Guidestar Safety Initiative.
Funding and deployment of these ITS projects represents a recognition of the need and value of ITS plus Minnesota’s commitment to the future.

PurposeBuild on infrastructure already in placeEmphasize innovative yet proven technologyTake a system-wide approachMoves Toward Zero DeathsStart to implement ITS Safety PlanPresents a model for other states
6
ITS Safety PlanDevelop ITS strategies and initiatives that reduce the number of vehicle traffic fatalities and serious injuries on roadways. Identified six ITS Critical Strategies supported by 22 ITS Safety Initiatives. The Safety Initiatives advance the six ITS Critical Strategies.Proactive in their approach to reducing the number of fatalities on Minnesota roadways.

Intersection Warning System
2007 Innovative Ideas Program

ProblemSafety at Unsignalized Intersections is a major concern. Intersection collisions are one of the most common types of crash, and in the United States, they account for nearly 2 million accidents and 6,700 fatalities every 2 million accidents and 6,700 fatalities every yearyear. However, a fully signalized intersection can sometimes be hard to justify in rural areas, due to the cost of installation, maintenance, and added delays to traffic on the major through streets...

IWS - Project Goal
Our Goal is to develop a low-cost, readily deployable, low maintenance system that can be used to improve
safety at low volume, non-signalized intersections.

Rural ITS ToolboxIntersection Intersection Warning
Low volume rural (non-urban) roadsRelatively high crash/near miss history Poor sight distance areasTemporary sight obstructions, i.e. cornfield intersectionSeasonal heavy traffic such as harvest time

PartnershipSEH has partnered with Network Transportation Technologies, LLC (NTT)Belief that we can be better at saving lives by efficient utilization of technology.Belief that we can do this with less infrastructure and reduced costs.Belief that Stand Alone Smart Systemspermit this. (Go where we haven't gone before)

Data Collection SystemStealthy small radar based traffic data collection (Stop Sign Mount)Provide detail speed data on approaching vehicles (Did it Stop?)
Time Stamp ( Time of day bad behavior?)
Self contained battery powered (>2 weeks ?)
Use Excel for analysis

Applications:Intersection driver performance. This system measures speed profile of each vehicle coming to stop sign.Work zone performance measurements. This system consists of one or more devices that log speed data of vehicle moving through workzone. Speed Limit determination measurements. This application requires speed data over a number of vehicles during a several day period. From this data the average speeds are determined and from this data speed limits are set.
