AMATS High Crash Network
AMATS High Crash Network
Several plans and analyses have identified high-crash or high-injury locations on the transportation system in the AMATS area. The presence of multiple sources of information can cause confusion or inefficiencies when planning projects. AMATS staff have compiled these sources into a single map displaying the high-crash network in the AMATS area, with a supporting table to provide further details on crash patterns for each corridor. The map and table could be used to inform project prioritization, scope, or design, and to identify areas where regular data analysis would be useful (for example, trends in crash rates).
Overview
The map and table represent a time-effective effort to compile currently available information to inform projects. The next update of the Safety Plan could build upon this with a more robust analysis that carefully evaluates crash patterns, including by mode and crash severity, to identify roads or hotspots within the AMATS area with the highest safety needs.

Staff combined these sources of information:
- 2024 AMATS Safety Plan (2017–2021 data; all modes and crash severities)
- DOT&PF Highway Safety Improvement Program (HSIP; top 10 corridors; 2018–2022 data; all modes; all crashes but weighted by severity)
- DOT&PF Strategic Highway Safety Plan (SHSP; 2016–2021 data; non-motorized injury crashes)
- MOA and DOT&PF Taking Action to Prevent Roadway Deaths (2018–2022 data; pedestrian crashes)
Each source considered all roads in the AMATS area and identified corridors, which have been overlaid on the combined map. The Safety Plan was the only source to identify hotspots (locations with over 70 crashes in 2017–2021), so the hotspots on the combined map come only from the Safety Plan, and thus represent all modes and all crash severities.
Table
To show patterns in serious crashes for each corridor, staff used crash data from DOT&PF for fatalities and serious injuries for all modes from 2013-2024 (all currently available data). This table evaluates only corridors, not hotspots, because the relatively small numbers of serious crashes at hotspots would mean the hotspot rankings would be influenced by chance. Corridor lengths vary, so the table ranks each corridor by the number of fatal and serious injury crashes per mile. Some of the corridors that rank low in the table may still have high-crash hotspots with a high safety need, and the overall crash patterns for a corridor may not represent crash patterns at any specific hotspot.
