New Lake Elmo Elementary School & Oak-Land Middle School August 1, 2024 Transportation Study Page 8 o There was a total of 24 crashes reported within the study area during the analysis period. The number of crashes ranged from a high of nine (9) crashes at the 10th Street/Lake Elmo Avenue intersection to a low of one (1) crash at the 10th Street/Keats Avenue and Manning Avenue/Oak-Land Middle School South Access intersections. o In order to determine the significance of the crashes, crash rates were calculated for each intersection and compared to average crash rates published by MnDOT for intersections with similar characteristics (i.e., traffic control, traffic volumes, lighting, environment, etc.) A higher than average rate does not necessarily indicate a significant crash problem. Therefore, critical rates were calculated to determine the statistical significance. If the actual rates are below the critical rates, crashes that occurred may be due to the random nature of crashes and not necessarily a geometric design or traffic control issue. Based on the results of analysis, which is illustrated in Figure 4, no study intersections are above the critical crash rate, indicating that no study intersections have a statistically significant crash problem. o It should be noted that one (1) fatal and four (4) serious injury crashes have occurred within the study area during the analysis period. Descriptions of the fatal/serious injury crashes, which are based on the police reports, are summarized below: o 10th Street/Lake Elmo Avenue – Fatal single vehicle run-off-road crash. Driver ran a stop sign at high speed, before exiting the roadway and hitting a tree. Based on the police report, the driver was intoxicated at the time of the crash. o Lake Elmo Avenue/Hudson Boulevard – Serious injury head-on crash. Driver crossed the centerline, colliding with oncoming traffic. Based on the police reports, drugs/alcohol may have played a role in the crash. o Lake Elmo Avenue/Hudson Boulevard – Serious injury angle crash. Side-street vehicle failed to observe right-of-way and pulled out into oncoming traffic. o 10th Street/Manning Avenue – Serious injury left-turn crash. Westbound left turning vehicle failed to yield to oncoming vehicle with green light. o 10th Street/Manning Avenue – Serious injury left-turn crash. Eastbound left turning vehicle failed to yield to oncoming vehicle with green light. o All eight (8) of the multi-vehicle crashes that occurred at the 10th Street/Lake Elmo Avenue were the result of vehicles running the stop signs or failing to yield right-of-way. o Six (6) of the seven (7) crashes at the Lake Elmo Avenue/Hudson Boulevard intersection were either minor injury or serious injury crashes, a majority of which were angle crashes.
