Minneapolis’ I-394 corridor (stretching from the Minneapolis central business district to the Hennepin County line with TH 55 to the north and TH 7 to the south is a ICM is critical in Minneapolis because of its heavily traveled commuter route with corridor and limited space to improve physical capacity. Using ICM strategies, the Minneapolis Pioneer Site hopes to reduce congestion and improve travel time reliability throughout the corridor.

The Minneapolis Department of Transportatoin is acting as the lead agency for ICM implementation, accompanied by Hennepin County, the City of Minneapolis, and Minneapolis Metro Transit. Minneapolis is fortunate to have close relationships between representatives from the county and city transit agencies and the State highway patrol. These relationships are facilitating the critical institutional cooperation that is critical to successful ICM.The Minneapolis ICM team is looking at combining managed lane and transit signal priority strategies to increase traffic flow along the corridor and is putting a strategic emphasis on the reliability of the equipment in the field to improve the quality and consistency of the information being sent to decision-makers in traffic management centers

Concept of Operations and System Requirements

• Concept of Operations for the I-394 Corridor in Minneapolis, Minnesota
• System Requirements Specification for the I-394 ICMS in Minneapolis, Minnesota

ITS Assets and ICM Strategy

The following are ITS assets that the Minneapolis Pioneer Site will leverage in their ICMS:

• Operations Centers
• Freeway Management System
• Arterial Network
• 511 Traveler Information
• ABC garages
• Transit Network
• I-394 MnPass HOT Lanes

Minneapolis plans to evaluate the following ICM strategies in the I-394 corridor:

• Earlier Dissemination of Traveler Information
• Comparative Travel Times
• Parking Availability at Park-n-Ride
• ABC Garage Display
• Reduced Incident Time
• Incident Signal Retiming Plans
• Ramp Metering
• HOT Lanes
• Dynamic Rerouting
• Special Event Transit and Parking Expansion
• Transit Signal Priority

Analysis, Modeling, and Simulation Overview

The USDOT developed the ICM AMS methodology to help transportation decision-makers identify the best ICM strategies for their needs under different conditions (such as planned special events, high traffic congestion, or major incidents). The AMS approach was designed to leverage the strengths of various analysis tools, such as travel demand models. The ICM AMS methodology can support corridor management planning, design, and operations by integrating macro-, meso- and microscopic simulation tool types and combining their capabilities.

ICM Scenarios Modeled:

• Major Incident Freeway
• Minor Incident Freeway
• Major Incident Arterial
• Minor Incident Arterial
• Special Event
• Weather Condition

In order to determine the effectiveness of each of these strategies, Minneapolis is using the following performance measures:

• Travel Time Reliability
• Vehicle and Person Throughput
• Incident Impacts on Delay
• Influence on Travelers’ Behavior
• Safety
• Emissions and Fuel Consumption
