In order from highest collision frequency, rate and severity level, the intersections are West Slaughter Lane and Manchaca Road; Lamar Boulevard and Rundberg Lane; Lamar Boulevard and Parmer Lane; U.S. 183 Service Road and Cameron Road; and I-35 Service Road Southbound and Martin Luther King Jr. Boulevard.
Proposed improvements include adding raised medians, modifying turning lanes and, in one case, adding a new lane. The goals include preventing drivers from making unsafe turns, reducing driver speeds, forcing drivers to yield and making crosswalks safer for pedestrians.
“At some locations, collisions are predominantly random and mostly associated with drivers’ errors,” Austin Transportation Department staff wrote. “However, some locations have particular collision patterns that are preventable and can be targeted with engineering countermeasures. ATD is adopting this procedure to target the preventable collisions and improve overall traffic safety in Austin.”
