A small slice of McKinney's road network is where most of the city's worst crashes happen, according to a draft traffic safety plan the City Council will discuss at its work session on Tuesday, Oct. 20.
The Safe Streets McKinney Comprehensive Safety Action Plan reviewed 7,778 crashes on city roads from 2020 through 2024. Of those, 35 killed someone and 180 caused serious injuries. The plan maps a "high injury network" of 42 corridor segments and 21 intersections that together make up 3.6% of the roadway network but account for 63.3% of the fatal and serious-injury crashes.
Where the risk is highest
The corridor with the highest score is South McDonald Street (State Highway 5) between Eldorado Parkway/Industrial Boulevard and Spur 399, a stretch the presentation notes TxDOT is already rebuilding. Other high-ranking segments include East Louisiana Street east of North Murray Street, Industrial Boulevard, several stretches of University Drive (US 380), Eldorado Parkway and Medical Center Drive.
The top-ranked intersection is University Drive at Community Avenue, where a city project to add capacity is under construction. McDonald Street at Stewart Road and at Eldorado Parkway/Industrial Boulevard come next.
Many of the listed locations already have work planned, designed or underway, from TxDOT reconstruction of SH 5 and the US 380 bypass to new roadway lighting installed this year along Industrial Boulevard and parts of US 380 and Eldorado Parkway.
Who gets hurt
Pedestrians, bicyclists and motorcyclists were involved in less than 4% of all crashes but more than 40% of the fatal and serious-injury crashes, the plan found. Most crashes involving people walking or biking happened in daylight, yet 56% of the ones that killed or seriously injured them happened at night.
Roads posted at 35 to 40 mph carried 45% of the deadly and serious crashes. Five behaviors (speeding, failing to yield on left turns, distracted driving, ignoring traffic controls and impaired driving) were behind 56.8% of them.
