511 TRAVELER INFORMATION PHONE NUMBER: Mn/DOT implemented 511 for wireless and landline callers
statewide on July 1, 2002. The service provides highway traffic, road weather, and some transit information. Over 60,000
calls have been received since the service was launched on July 1. Daily call volumes during the summer period have leveled
off at an average of 1,000 per day – 10 times more than the previous 800# service in the same summer period. Work continues
on improving voice recognition and on exploring future enhancements that include traffic congestion reports. A new website
( has been implemented that provides the same information on the Internet that is available via dialing 511.
Mn/DOT’s Commissioner Tinklenberg is chairing the National 511 Deployment Coalition. Project Contact: Ginny
Crowson, Phone 651-284-3454,

CARS – CONDITION ACQUISITION & REPORTING SYSTEM: CARS was implemented on December 7, 2000.
CARS is a database of road conditions, restrictions and incidents. It was developed through a pooled fund with the states of
Iowa, Kentucky, Missouri, Washington, New Mexico, New Hampshire, Vermont, Maine, and Alaska. The public receives the
information by website, 511, and cable TV. Mn/DOT has implemented dozens of enhancements for permits, emergencies, and
communications. We continue to improve accuracy, reliability and timeliness of reports, and identify further applications for
the system. We envisioned CARS as an 8/5 program, but we are being defaulted to a 24/7 program because the website and
511 are 24/7. Project Contact: Debra Fick, Phone: 651-296-3029,

WWW.TRIPUSA.COM: Mn/DOT and its partner, Castle Rock Services, deployed advanced traveler information via using both user selectable road segments and a user-subscription e-mail push system. CARS is the primary data
source for the site. On July 1, 2002, Mn/DOT also launched, at Mn/DOT site based on that also
utilizes CARS as its primary data source. Project Contact: Ginny Crowson, Phone 651-284-3454,

CABLE TV ATIS OPERATIONAL TEST: Mn/DOT and its partners (Minnesota Satellite and Technology, Sufficient
Systems, Arvig Communication and Sjoberg Cable) are testing rural cable TV systems as a medium for providing advanced
traveler information (real-time road condition and incident reports) to rural travelers. The system has been operational since
mid-2001 and an independent evaluation will be conducted before the end of 2002 to determine applicability for future
expansion. Project Contact: Ginny Crowson, Phone 651-284-3454,

STATEWIDE ROAD/WEATHER INFORMATION SYSTEM (RWIS): Mn/DOT is currently receiving information from
92 RWIS stations located throughout the state. This system is fully networked and accessible using Mn/DOT’s intranet or the
Internet. In addition to providing users near real-time pavement and atmospheric data, this system also provides detailed
forecast information, access to AWOS and ASOS sites within Minnesota, local and national radar and satellite information, and
access to R/WIS sites in 4 adjoining states. Project Contact: Curt Pape, Phone: 651-297-1798,

REGIONAL TRANSPORTATION MANAGEMENT CENTER (RTMC): The new Regional Transportation Management
Center for the Twin Cities Metro Area has been developed as a 50,000 square foot addition to the Metro Division headquarters
in Roseville. It is scheduled to open later this year and will include staff from the existing TMC, State Patrol Dispatch, and
Maintenance Dispatch. This facility will also support statewide initiatives such as traveler information, surface transportation
security, and the Amber Alert program. Project Contact: Glen Carlson, Phone: 651-582-1343,
TRAFFIC MANAGEMENT BACKBONE DEPLOYMENT: Deployment of the backbone traffic management ITS user
services has been extended to 270 miles of Twin Cities freeways, covering about 90% of the network. This includes
surveillance via traffic detectors and CCTV, dynamic message signs, ramp metering, a freeway service patrol fleet (Highway
Helpers), a comprehensive traveler information program, HOV lane and facility operations, and an incident management
program. Contract lettings over the next several years will complete the 300-mile backbone ITS deployment. Project

implements nine out-state co-located dispatch and communication centers with CAD/AVL/MDC, road/weather information
systems and road condition reporting systems to benefit the traveling public and reduce Mn/DOT’s operating costs. It is the
basic platform for Advanced Traffic Management Operations centers in Duluth, St. Cloud, Mankato and Rochester (listed
separately). It includes computer-assisted dispatch, mobile data terminals and automatic vehicle location for the Minnesota
State Patrol (MSP). TOCC Operators will use the equipment to improve incident and emergency management, to respond to
weather-related problems and to improve traveler information. Other major components are communication infrastructure for
both center to center and center to vehicle. Project Contact: Tom Peters, Phone: 651-282-2469,

These ITS programs provide freeway and arterial traffic management for Duluth, St. Cloud, Mankato and Rochester. Multiple
stakeholders; sharing/control of information; new traffic management software; communication infrastructure; private cost
sharing; operation and maintenance tails. Common goals required active participation and cooperation between stakeholders.
The systems maximize the use of existing public and private communication infrastructure. ADDCO traffic operation
software (VTOC) has been successfully developed, tested and implemented. Project Contact: Tom Peters, Phone: 651-282-

assistance lateral guidance and collision avoidance technologies. Evaluation of performance, benefits and practicality of these
technologies on safety and efficiency of snowplows, ambulances and police vehicle in extreme low visibility conditions;
partnership contracts; provision of infrastructure for lateral guidance (magnetic tape and DGPS) and collision avoidance
(radar). System design and installation of field infrastructure and vehicle instrumentation and the first year of field test is
complete. Evaluation of the field test is underway. Mn/DOT is continuing the test for a second year to allow for further
system development and hardening and to gather additional data needed due to the unusually mile winter during the first year
of testing. Project Contact: Brad Estochen, Phone: 651-296-2984,

SAFEPLOW: The SAFEPLOW project uses new technology to allow plow operation in low visibility conditions. The next
field operational test will begin on October 1, 2002. At this time, we have tested the operator both in a simulator as well as in
the real world. Differential Global Positioning System (DGPS) is used for lateral guidance. The other primary technology on
the vehicle is a 360-degree radar system that has been developed and is being tested. The project has been developed by input
from drivers to make sure this tool will fit their needs. The "gang plowing" task was successful and allowed one vehicle to
move based on the lead vehicle movement. Project Contact: John Scharffbillig, Phone: 651-215-0402,

field operational test of low-cost active warning systems at low-volume highway-rail intersections. Example technologies and
functions include solar power, LEDs for flashing lights, GPS for train location, active advanced warnings, fault diagnostics and
automatic reporting and data collection. Limited testing of the system has begun with the full operational test beginning in
March 2003. Project Contact: Dayue Zhang, Phone: 651-284-3436,

The NIT project developed and implemented a long-term traffic detection technology test facility. The test infrastructure,
testing, and data collection has been completed. A multi-state technical working group adopted the standardized reporting
procedures. The final draft report is being reviewed and will be available on the website: in
September of 2002. The field test and evaluation of the NIT Bicycle and Pedestrian component has begun. Project Contact:

winter 2002. Project Contact: Farideh Amiri, Phone: (651) 296-8602,

I-90 AUTOMATED GATE CLOSURE: This is a private-public partnership project to seek new and innovative technologies
and methodologies to control traffic through the use of gates and dynamic message signs and to develop creative and novel
ways to provide transportation services, which are mutually beneficial to all parties. All hardware and software were designed,
installed and tested. The acceptance test was completed successfully. The system will be tested and evaluated in winter of
2002/2003. Project Contact: Farideh Amiri, Phone: (651-296-8602),

FIELD TEST OF TRUCK PRIOROTY AT TRAFFIC SIGNALS: The project goal is to improve the operation of heavy
commercial and freight trucks passing through traffic signal controlled intersections on rural high-speed highways. A request
for proposals will be published in September 2002. Project Contact: Farideh Amiri, Phone: 651-296-8602,

POLARIS STATEWIDE ITS ARCHITECTURE UPDATE: Polaris was the Minnesota statewide ITS architecture
developed prior to completion of the National ITS Architecture. The approach for updating the Polaris architecture is similar
to that used in architecture workshops across the United States. The unique difference is that this project went beyond the
normal ITS architecture to address some of the interface issues important to our stakeholders. The final report has been
completed. Project Contact: Ben Osemenam, Phone: (651-297-5651),

ITS/CVO architecture that was designed to enhance Minnesota’s commercial vehicle regulatory activities. Using open
interface standards, we are able to deliver data electronically in the three functional areas of safety, credentials, and electronic
screening. An electronic screening system that allows safe and legal commercial vehicles to bypass roadside inspection
facilities without stopping is operational at the St. Croix Weight Station facility. Electronic registration and credentialing for
interstate vehicles has been completed. Project Contact: Andrea Kampa, Phone: (651-405-6087),

SAFETY AUTOMATED INTELLIGENT LOCATOR (SAIL): The second phase of a maintenance vehicle/operational
test using automatic vehicle location technology to streamline and improve customer service and safety. The first phase
demonstrated the technology performed successfully in an urban environment. This phase will concentrate the effort in
'subareas' of both rural and metropolitan districts, providing more direct connect between vehicles, data collection and
operation centers to determine the operational benefits of the system. An RFP will be published in September 2002. Project
Contact: Sue Lodahl, Phone: 651-282-2281,

ITS STANDARD MIGRATION PROJECT: This project will develop a path for Minnesota’s ITS activities to follow in
order to migrate towards statewide use of ITS Standards. This project consists of four stages -- migration planning; equipment
testing and evaluation; deployment plan, training; and implementation. We are currently working on the planning stage of the
project. Project Contact: Ray Starr, Phone 284-3434,

METRO DIVISION TEN YEAR ITS PLAN: The ITS “Ten-Year Vision Plan” identifies optimized traffic flow on arterials
as a key benefit. Metro Traffic also considers this a top priority, and during the past year has focused on optimizing the timing
and coordination for the 650 traffic signals we operate. Project Contact: Glen Carlson, Phone: 651-582-1343,

METRO DIVISION ITS MAINTENANCE: ITS maintenance responsibilities have been assigned to Metro Traffic
Engineering, thus completing the business cycle of planning, design, implementation, operation, and maintenance within Metro
Division. Most Metro Traffic Engineering unit heads have attended the National ITS Architecture Training, and several have
also had the Turbo Architecture training. Traffic management and ITS planning have been integrated into the Metro TIP, and
funding needs are included in CIC deliberations. Project Contact: Glen Carlson, Phone: 651-582-1343,
                                                    PLANNED PROJECTS

WIRELESS VEHICLE PROBES: Pertinent vehicle operation data from on-board vehicle computers and additional
environmental data from the vehicle’s surroundings will be collected and transmitted via wireless communications systems to a
central location. Various methods of data transmission will be tested to determine the reliability of vehicle-to center wireless
data transmission from a variety of locations in and around the Twin Cities metropolitan area. Next, the accuracy, usefulness,
etc., of the data will be assessed to determine the potential benefits of using vehicles as probes. The data will include
environmental data such as air and surface temperatures and surrogate vehicle data will be used to determine additional
conditions using windshield wiper action, headlight on/off, anti-lock brake actuation and traction control/stability control
actuation, etc. The GPS system will be used to determine roadway being used and approximate travel times over key
segments. Also, additional testing of the system in more remote rural settings could be conducted where the vehicle would
download information when wireless communication was available and would store information when wireless
communications was not available for later download.

VISION DETECTION SYSTEM: This project will test a vision detection system that measures particulate matter in the
atmosphere to determine if low visibility conditions exist. In the event of low visibility, an alarm would be sent to the State
Patrol and Mn/DOT TOCC dispatch center. The dispatchers would then confirm the visibility conditions through the use of
existing CCTV surveillance cameras and program appropriate messages on existing variable speed limit signs (VSLS) and
variable message signs (VMS) or take other appropriate actions. Options to automate the system for the placement of pre-
selected messages on the VSLS and VMS will also be investigated.

TRANSIT STATUS AT BUS SHELTERS: In the initial research project, a system will be developed that uses the current
AVL system information regarding bus status and projected arrival times to be transmitted over the existing radio system to a
receiver located at the selected bus shelters. Specially designed variable message signs (vandal resistant and readable from
short distances) will be used to display the bus arrival status information.

WORKZONE VARIABLE SPEED LIMITS/ATMS: The objective of this field test is to determine the extent to which
VSL systems can improve compliance, increased credibility of speed limits, improved safety, and improved traffic flow in
work zones. The system to be implemented will include a VSL system, advance VMS, sensors and detectors, wireless
communications, software, and automated data collection functions. The actual deployment and test of the system will include
system operations and monitoring and data collection and analysis. Automated data collection routines with software
algorithms will be developed to support a thorough evaluation of the system.

PORTABLE DIVERSION MGT / DYNAMIC SPEED ADVISORY: The proposed project will provide real-time traffic
information to motorists through the use of off-the-shelf portable VMS and wireless communications. The goal of the project
is to provide motorists with real-time information so they can make travel route decisions based on current conditions. The
project will evaluate the system’s impact on motorists’ decisions to use alternate routes. The project will obtain volume counts
from existing loop detectors to conduct a before and after study of the route diversions. The study will also address whether
information is more effective when only displayed during periods of congestion, and what type of information is most effective
(i.e. speed or travel time data).

ITS SCOPING STUDIES: This effort will develop ITS scoping studies for the final four Mn/DOT districts that were not
included in the initial round of scoping studies. The purpose of studies is to identify and rank the transportation needs for each
district and to evaluate potential ITS solutions to address those needs. The resulting studies will serve as the base for future
ITS deployment activities in each district. The TOCCs will be the focal point for these efforts as any deployment is expected
to be integrated directly into TOCCs.

ITS MEGA CORRIDOR: Proposed ITS Mega Corridor projects include a mix of new-innovative strategies, takes advantage
of current and past operational tests, integration of existing systems, expansion of advanced traffic management systems and
operational enhancements. The ITS Mega Corridor Program will focus on nine key program areas including Communication
Infrastructure, Advanced Traveler Information Systems (ATIS), Traffic Management Operations/Advanced Traffic
Management Systems (ATMS), Maintenance ITS Enhancements, Metro Traffic Management Center (TMC) and St. Cloud
Transportation Operations Communications Center (TOCC) Integration/Information Sharing, Highway and Rail Grade
Crossing Improvements and Transit priorities.

project is to establish an integrated rural traffic management and traveler information system between two of Mn/DOT’s rural
districts. The project will focus on the implementation of variable message signs at key locations along I-35 and I-90 and at
the junction of I-35/I-90. The proposed system will be operated in a joint and integrated manner between Districts 6 and 7 to
facilitate seamless traveler information between the two districts. The project will address operational roles and
responsibilities, coordination needs and integration between the two districts for operation of the VMS. Policies and
procedures for implementing messages, types of messages, and scenarios for use will be developed. Options for future
integration with Wisconsin, Iowa and South Dakota will be considered.

DULUTH/SUPERIOR BRIDGE SURVEILLANCE SYSTEM: The goal of this project is to enhance safety, security and
traffic management capabilities along the two bridges that connect Duluth and Superior. Initial ITS deployment activities as
part of the Duluth Transportation Operations and Communications Center (TOCC) project provided Closed Circuit Television
(CCTV) camera surveillance at key locations along I-35 in Duluth and for a portion of one bridge that connects Duluth to
Superior but there is currently no camera surveillance along the other bridge. This project will include additional
enhancements to the Duluth TOCC ITS program by providing full CCTV camera coverage along both bridges. The cameras
views will be fed back to the Mn/DOT and State Patrol Dispatch Center in Duluth and shared with the Superior/Douglas
County Dispatch Center in Superior. Dispatchers will utilize the camera views for incident detection, verification, to enhance
incident response and security and for interstate traffic management.

NORTH/WEST PASSAGE (I-90/94): The North/West Passage Coalition will provide opportunities to coordinate efforts and
meet the needs of the corridor states with ITS solutions. The corridor coalition has already identified the top problems and
needs of the corridor to establish some focus to the program. Top problems/needs are lack of consistent/adequate traveler
information, weather related incidents, lack of rural wireless communications, inconsistent reliability in CVO information, and
lack of coordination at borders. In response, the coalition has identified priority ITS projects for the corridor that include
coordinated ATIS, developing coordination with vehicle manufacturers for telematics, corridor-wide collection and exchange
of weather/pavement conditions data, development of corridor-wide communication partnerships, deployment of CVO traveler
information systems, and deployment of dynamic message sign systems along the corridor and coordination across state

traveler information input methods are being pursued by Mn/DOT as part of the integration program. Mobile devices have
already been successfully implemented for condition reporting. To integrate information from differing jurisdictions, data
entry interfaces will be developed for non-State entities to use to enter condition, construction, and incident data.

Data Processing – Upgrades to the ATIS system hardware and software are planned to keep pace with the performance
demands as additional data sources and user services are created.

Data Distribution - Several initiatives will offer new methods and expand upon existing methods providing travelers access to
information. Among the methods under consideration are: mobile data devices, cell phones, broadcast radio, cable TV, closed
circuit TV, Variable Message Signs (VMS) and Web applications.

NATIONAL MAYDAY READINESS INITIATIVE:Mn/DOT has submitted an application to the USDOT for the field test
of a system that enables the emergency calls from telematics service providers to 911 call centers to be made over the true 911
system with accompanying digital location and callback information rather than the current method relying on traditional
telephone lines and voice conveyance of the location and callback information. In addition, this project will provide a second
path and delivery mechanism for data to be delivered to the 911 call centers, emergency responders, trauma centers, etc. The
secondary data path will provide a low cost method for the 911 call centers to obtain the location information. This second
data path will be developed to be expandable and scalable to support a wide variety of additional data that will be available
from the onboard crash sensor systems, medical record information provided by subscribers to telematics service providers for
emergency use, etc.
