MEMORANDUM
To: I-94 IRC Policy Copy: I-94 IRC Project
Advisory Committee Team
(PAC)
From: URS I-94 IRC Project Team
Date: December 13, 2001
Subject: 2025 Operational Characteristics of I-94 IRC Transportation Alternatives
Introduction
This memorandum summarizes the projected 2025 operational characteristics of I-94 for five transportation
scenarios. These are:
• Base Network: Existing (E) plus Committed (C) Transportation Improvements,
• Alternative 1: Improved Local Arterial System
• Alternative 2: Expansion of I-94 to 8-lanes between I-494/694 and TH 241
• Alternative 3: Improved Local Arterial System (Alt. 1) plus I-94 Expansion to 8-lanes (Alt. 2)
• Alternative 4: Improved Local Arterial System (Alt. 1) plus I-94 Expansion to 10-lanes (limits of
expansion)
In the previous memorandum dated November 13, 2001 two base transportation scenarios were presented.
In addition to the Existing plus Committed transportation network, a scenario containing eight additional
interchanges was presented. In the analysis of these two scenarios it was shown that the additional
interchanges would have an impact on increasing traffic on I-94. However, the impact of the increased traffic
on projected travel speeds was minimal. The projected speeds had been determined using a speed calculation
methodology that was more applicable to estimating speeds on roadways with traffic signals and access
breaks, unlike I-94, which is a limited access freeway with no traffic signals. Therefore, it was decided to use
the TRANPLAN model output to determine future travel speeds. TRANPLAN calculates speeds based on
the Bureau of Public Roads (BPR) curve, which determines the relationship of speed to capacity. The primary
difference with respect to the results obtained from the aforementioned speed prediction formula is the change
in the speed of heavily congested roadway segments. The lowest speed that had been allowed by the speed
prediction formula is 48.0 mph, regardless of congestion levels. 1 Using TRANPLAN's methodology, the
speeds on the same segments were calculated to be under 40-mph (38.9) for the Existing plus Committed
Projects scenario. Although this does not represent a great differential, it is a more accurate method of
calculating speed and was therefore used in calculating projected speeds.
1 The speeds reported in the November 13 memorandum were calculated using the speed prediction formula.
The four alternatives that are being presented in this memorandum do not represent the universe of
transportation improvements. The improvements were identified in cooperation with the Technical Advisory
Committee members.
Transportation Scenario 1: Existing (E) + Committed (C) Improvements
Committed projects are those that have been listed in the State Transportation Improvement Plan (STIP) or
either District 3 or the Metro Divisions 20-year plans. The primary committed improvements with respect to
I-94's operation are described in the categories listed below.
Freeway Expansions/Extensions
• Expansion of I-694/94 to 6-lanes between Brooklyn Boulevard and Hemlock Lane (outside of corridor)
• Extension of TH 610 freeway to I-94 (intersects I-94 at approximately 101 st Avenue N. in Maple Grove)
• Expansion of I-94 to 6-lanes between Rogers and Monticello, resulting in the continuation of a 6-lane
cross-section from the I-494/694 split in Maple Grove to TH 25 in Monticello.
New or Improved Interchanges
• New interchange (system to system) with TH 610 in Maple Grove.
• New interchange (full access) with TH 18 in Monticello. To accommodate this new interchange, the
existing partial interchange located at CSAH 75 would be eliminated.
• New interchange (full access) with CSAH 75 (south I-94 junction, near Industrial Park) in St. Cloud.
Committed County or Local Improvements (only projects likely to impact corridor travel patterns)
• Frankfort Parkway (Monticello)
• Enhancement of CR 18 (Wright County)
• Extension of CSAH 37 alignment to the west (Otsego)
• Extension of Hemlock Lane to CSAH 109 (Maple Grove)
Alternative 1: Improved Local Arterial System
This alternative consists of improvements to the arterial (non -freeway) roadway network. The improvements
consist of either capacity improvements through the addition of lanes, turning lane treatments, extensions of
existing roadways, or new roadway connections. The roadways and total of 115 miles of associated
improvements contained within this alternative were identified in cooperation with the Technical Advisory
Committee (TAC) members. These represent a first attempt at the identification of the most effective
improvement measures. Table 1 (attached) lists the identified measures and Figure 1 (attached) displays these
improvement measures on a map.
Alternative 2: Expansion of I-94 to 8-lanes between I-494/694 and TH 241
This alternative includes only those improvements identified in the Existing plus Committed scenario. In
addition to these measures, I-94 between the I-494/694 split and TH 241 is widened to 8-lanes.
Alternative 3: Improved Local Arterial System (Alt. 1) plus I-94 Expansion to 8-lanes (Alt. 2)
This alternative is a combination Alternatives 1 and 2. It contains the arterial improvements listed in Table
1 plus the expansion of I-94 to 8-lanes.
Alternative 4: Improved Local Arterial System (Alt. 1) plus I-94 Expansion to 10-lanes
This alternative incorporates the improvements identified in Alternative 1 and the expansion of I-94 between
I-494/694 and TH 241 to 10-lanes.

Future Transportation Scenario Traffic Volumes
Using the TRANPLAN travel demand model developed for the I-94 IRC study it is possible to estimate or
project the impact of various land use and transportation scenarios. The model was developed in conjunction
with the I-94 IRC partners who assisted in the development of existing and projected transportation and socio-
economic information needed for the model. 2
The I-94 corridor was divided into six segments for the travel speed analysis. Table 2 displays the breakdown
of the corridor segments.

The results of the speed prediction analysis indicate a high risk for traffic congestion along the I-94 corridor.
Traffic congestion risks are classified as severe, moderate. or low according to MnDOT's "A Guide for Plan
Development and Corridor Management." Table 5 displays the Congestion Index for each of the six corridors
by Alternative.

The distinction between the Year 2025 Transportation Alternatives will have impacts on the operations of the
I-94 Corridor. Ultimately, the base differences between the Alternatives can be found in Segments l and 2.
In general, the other segments of the Corridor are similar. Alternative 1 is expected to have vehicle speeds
below 50.5 mph in both of these segments. Additionally, this alternative is expected to have the least amount
of capability to increase the travel speeds in Segments 1 and 2 on I-94 as an individual alternative. Alternative
2 is expected to have more of an affect on travel speeds than Alternative 1 in these segments. but is still
projected to have an corridor -wide travel speed less than the established goal of 60 mph. The speed prediction
results indicate that only Alternatives 3 and 4. which both incorporate the arterial improvements of Alternative
1 plus an expansion of the freeway system will achieve the IRC travel speed goal of at least 60 mph.

Summary
This memorandum summarized projected 2025 operational characteristics of I-94 for 4 transportation
improvement alternatives. These were:
Alternative 1: Improved Local Arterial System
Alternative 2: Expansion of I-94 to 8-lanes between I-494/694 and TH 241
Alternative 3: Improved Local Arterial System (Alt. 1) plus I-94 Expansion to 8-lanes (Alt. 2)
Alternative 4: Improved Local Arterial System (Alt. 1) plus I-94 Expansion to 10-lanes
The arterial improvement projects, which were identified in coordination with the TAC members, are expected
to have a considerable impact on the supporting transportation network of I-94. Although the transportation
improvements to the Local Arterial System, as designated for Alternative 1, will provide considerable
opportunities for improved mobility in the region, it is not expected to attain the IRC goal of 60 mph
independently. Alternative 2, which includes the expansion of I-94 to 8-lanes between I-494/694 and TH 241
but no improvements to the local arterial system, is not expected attain the speed goals as found in the speed
prediction analysis. Additionally, it is expected to have the highest projection of daily traffic on I-94 overall.
Alternatives 3 and 4, which are both projected to meet the travel speed goals set by the IRC program, include
the improvements to the local arterial system (Alternative 1), in addition to an expansion of travel lanes on I-
94. Alternative 4, which included an expansion of I-94 to 10-lanes between I-494/694 and TH 241, may be
excessive because of its projected impacts on daily traffic. Overall, Alternative 3, which incorporates the
improved local arterial system (Alternative 1) with the expansion of 1-94 to 8 travel lanes (Alternative 2),
appears to be the best of the four evaluated alternatives. This alternative meets the guidelines set by the IRC
program, has the highest systemwide average speed of 35.05 mph, and seems the most feasible option for
attaining the corridor travel speed goal of at least 60-mph.
The next memorandum will focus on the costs associated with each of the alternatives, and will also assess the
impact of additional access or interchanges on each alternative's performance. This memorandum will be
prepared and distributed in mid -January, 2002.
