Freeway Volume-Crash Summary Twin Cities Metropolitan Area Purpose and Need The purpose of this report is to identify segments on the metro area freeway system that experience high numbers of crashes. This information is then used for: identification of locations that experience higher crash rates due to recurring congestion. project planning resource allocation (Traffic Management Systems, FIRST routes, incident management, etc.) This report is typically published on an annual basis. Data within this report represents 22 peak periods and 24-hour volume levels, crashes, and crash rates for each freeway segment. Introduction This report is a summary of the metro area freeway system s crash data and volume data in 22. The report has been developed by the Traffic Management Center since 1975 and was primarily used by TMC personnel to help establish priorities for future traffic management systems. This year the report has been reformatted to help broaden the audience of the report. Graphical representations of the data where added to make the report more user friendly and to show the connection between congestion and freeway crashes. Congestion and Freeway Crashes Freeway congestion and freeway crashes are related. Freeway congestion can be defined as either recurring congestion or incident related congestion. Recurring congestion is congestion that occurs at the same location on a daily basis due to some type of roadway characteristic that affects traffic flow such as a major interchange, lane drop, or weaving traffic. Incident related congestion can be caused by a crash, a stalled vehicle, debris on the roadway, adverse weather, or a special event. According to the FHWA, incident congestion accounts for up to 5% of the total congestion. 1

Crashes by Peak Period AM Peak 16% Off Peak 53% PM Peak 31% Increased congestion increases the potential for crashes to occur on the freeway. In 22, there were 9,439 crashes on metro area freeways. As the chart entitled Crashes by Peak Period shows, 47% of the crashes occurred during the peak travel hours. The peak hours consist of 6: am to 8:59 am during the AM Peak and 3: pm to 6:59 pm during the PM Peak, Monday through Friday. Weekends and non-peak weekday hours make up the Off Peak crashes. While peak hours consist of only seven hours a day or 2% of hours in a week, Monday through Friday, they represent almost half the number of freeway crashes. Freeway crashes are attributed to shock wave activity, merging traffic, and weaving traffic on congested roadways. These types of crashes are typically side-swipe or rear-end type collisions. The potential for more severe crashes typically occurs where free flow traffic and congested traffic converge. Examples include when free flow traffic meets slower moving congested traffic around a horizontal or vertical curve where the congested traffic may be unexpected. Another situation is where one or two lanes of traffic are congested due to a high volume entrance or exit ramp and adjacent lanes are free flowing traffic. Incident-related congestion is unexpected since it can occur during peak or non-peak hours and in areas where motorists may not expect slow moving traffic. A study done by the Traffic Management Center in 1982 found that 13% of traffic crashes were secondary crashes from incident-related congestion. An example of how incident congestion can cause secondary crashes occurred on February 1, 22. One crash on I-35W during the mid-day hours caused congestion on I-35W and Highway 62 over a two hour period, which led to six additional crashes. Most of these crashes occurred at the boundary where free flow traffic meets congested traffic. Incident from Feb 1 st, 22. One non-rush hour crash led to 6 others (including one injury crash) over a 2-hour period. 2

Study Methodology The freeways studied in this report are shown in the map on page 5. Each interstate and trunk highway is divided into sections with breaks based on changes in traffic volumes and other freeway characteristics. The study uses crash data from the Department of Public Safety's crash record database. Mn/DOT s Office of Transportation Data and Analysis processes the data with a crash analysis routine applied to the Transportation Information System (TIS). Crash data include only vehicular crashes on the mainline; interchange-related data is not included. Traffic volume data was obtained from the RTMC and the Office of Transportation Data Analysis. Each freeway link between entrance and/or exit ramps was assigned an annual average daily traffic volume (AADT). For even years (1998, 2, and 22), the AADT is based on actual traffic counts. For odd years (1999 and 21) AADT is based on actual counts recorded from the previous even year and projected to the next year s levels. Averages of link volumes, weighted for link distances, on each part of a freeway section were used to determine the average volume for each freeway section. Individuals using data from this report should be aware that weather, construction, and maintenance activities were not analyzed with respect to crash rates shown. Crash rates are expressed in units of crashes per million vehicle miles traveled (Crash/MVM) and calculated as follows: Annual Rate = Total Annual Crashes x 1,, Section Length (Miles) x AADT x 365 Peak Period Rate = Total Annual Peak Period Crashes x 1,, Section Length (Miles) x Average Period Volume x 26 Peak periods for this study are from 6:-8:59 A.M. and 3:-6:59 P.M. weekdays. 3

Segment Definition For purposes of this report, freeway segments are generally defined from the lowest logpoint listing number to the highest logpoint listing number of a particular section of roadway. The limits of the first study segment for each corridor includes two interchanges. The next segment of that roadway starts just past the previous interchange and ends just past the next interchange. Segment definitions continue in this manner to the end of the reported roadway. NOTE: Only crashes occurring on the mainline are included no interchange ramps or overpass crash data is included in this study. Example: SECTION OF I-94 CORRIDOR Segment 1: MN 11 to I-494 This is the first segment reported on this roadway in this study. The logpoints used includes the crashes that occurred just prior to the Hwy 11 interchange to just past the I-494 interchange. Segment 2: I-494 to CR 81 This segment includes crashes that occurred from just past the I-494 interchange to just past the CR 81 interchange. Segment 3: CR 81 to I-694 This segment contains crashes that occurred from just past the CR 81 interchange to just past the I-694 interchange.

Summary of Results The table below summarizes yearly crash totals and crash rates for 1996 through 22. There were 9,439 crashes in 22, resulting in an urban freeway crash rate of.96 Crashes/MVM. Crashes rose slightly from the year 21 when there were 9,395 crashes, or.92 crashes per million vehicle miles in a 24 hour, 7 days per week period. During the AM peak periods, there were 1,556 crashes in 22, resulting in a crash rate of 1.64 Crashes/MVM. During PM peak periods, there were 2,886 crashes in 22, or 2.27 Crashes/MVM. As seen in the line graph, crash rates during the peak periods have continued to increase since 1996, due mainly to increased levels of congestion. 24 Hr AM (6:-8:59) PM (3:-6:59) Year # of Crashes Crash Rate # of Crashes Crash Rate # of Crashes Crash Rate 1996 8,739 1.15 1,277 1.26 1,895 1. 1997 7,715.86 1,332 1.67 1,739 1.63 1998 7,532.83 1,312 1.62 2,251 2.6 1999 8,441.89 1,456 1.75 2,43 2.18 2 11,167 1.17 2,46 2.43 2,93 2.55 21 9,395.92 1,526 1.69 2,798 2.31 22 9,439.96 1,556 1.64 2,886 2.27 Crash Rates Trends 3 2.5 Crash Rate 2 1.5 1.5 1996 1997 1998 1999 2 21 22 Year 24 Hr AM (6:-8:59) PM (3:-6:59) 6

Crash Map The following map graphical shows the frequency of crashes on metro area freeways for both the AM Peak Period and the PM Peak Period combined. Crashes were plotted as the number of crashes per reference point. Since reference points on metro area freeways are approximately one mile apart, this map represents the frequency of crash as the number of crashes per mile. Approximately half of the segments on the map were in the category of to 9 crashes per mile. The remaining 5% had greater than 1 crashes per mile with 5% of the segments having greater that 44 crashes per mile. The maximum number of crashes per mile for both peaks was 137, which was on I-94 in the I-35W commons. Comparing the following crash map with the congestion maps from the 22 congestion report, the correlation between congestion and crashes can be seen. Areas experiencing heavy congestion also show a high frequency of crashes. The congestion maps are included in the appendix of this report for reference. 9

SELECTED INTERSTATE AND STATE ROADS How To Read This Section The following pages provide more detailed information on selected metro area freeways. The first page for each metro area freeway has a bar graph that shows the trends in crash rates from 1996 to 22. Each grouping of bars in the graph represents a specific segment of that freeway. Individual bars within the grouping then represent the crash rate for a given year. The table below the bar chart represents 22 volume and crash data for that freeway. The second page for each freeway contains two bar charts that show the number of crashes per reference point during the AM and PM peak periods. Reference points on metro area freeways are about one mile in length. The purpose of these charts is to show locations where there are a high number of crashes. These locations are typically at major interchanges, bottlenecks, and area experiencing high levels of congestion. Bar chart showing trends in crash rates for each segment. Table summarizing 22 volume and crash data for each freeway segment. Number of crashes per year by reference 11

Heaviest levels of congestion on I-35E are on the segment from I-94 to MN 36 during both the AM and PM peak periods. The 24-hour crash rate for this section is the highest segment for I-35E with a rate of 1.35 Crashes/MVM. Crash rates during the AM and PM peak periods are 3.28 Crashes/MVM and 3.22 Crashes/MVM. Referring to the I-35E Crashes per Reference Point chart for the PM peak period, a high number of crashes occur on I-35E from I-94 to Maryland Ave due to increased levels of congestion and merging traffic. Shockwave activity traveling back into the commons of I-94 and weaving traffic contributes to crashes in this area. 6 I-35E 24 Hour Crash Rate Trends 5 Annual Crash Rate Per MVM 4 3 2 1 S.

In 22, the 24-hour crash rates increased substantially along the I-35W segments from the east junction of MN 62 to the east junction of I-94 in Hennepin County. The number of crashes accounted for about one-third of the total number of crashes along I-35W for the 24-hour period. Congestion on this segment is heavy in both directions during both the AM and PM peaks periods. The highest number of crashes per reference point for the AM peak period occurs at Cliff Rd. This area is heavily congested in the morning from the Minnesota River Bridge back to MN 13. The PM peak period sees the highest number of crashes per reference point between MN 65 and Lake St. Crashes occur here in the southbound lanes of I-35W due to shock waves, merging traffic from downtown, and weaving traffic as motorists switch lanes for the MN 62 junction downstream.

The I-394 to West I-35W segment of I-94 had the most crashes, 355 crashes in a 24 hour period. While there were 86 more crashes at this location than the 24 hour period in 21, the AM peak increased more than 7% from 29 to 5 crashes. In 22, the greatest number of crashes during any peak period at any reference point along Twin Cities metro freeways occurred at MN 65/I-35W. There were 17 crashes during the PM peak period at this location. Crashes on westbound I-94 at MN 65/I-35W during the PM peak period are attributed to heavy congestion, merging traffic from I-35W and Hiawatha Ave., and weaving traffic as motorists switch lanes for the I-394 junction downstream. The segment of I-94 that showed the greatest increase in the number of crashes was MN 11 to West I-494 where total crashes increased from 192 in 21 to 292 in 22 over a 24 hour period, a 5+% surge.
