In the first year of the road diet trial (from May 2018 to May 2019), 37 accidents were reported in the trial area, compared to 26 crashes for the same timeframe in the previous year. While traffic accidents are never an ideal situation, it’s not uncommon for areas to experience an increase in traffic crashes for a brief time period after experiencing a change in traffic patterns. In fact, the 42% increase in year-over-year traffic accidents (26 versus 37) is not the largest percentage increase in accidents this corridor has seen in the past 5 years.
In 17 of the 37 crashes reported in the trial area since data collection began, a motorist disregarded a traffic control signal (ran a red light or stop sign) on Buttles or a cross street and experienced a collision. These types of crashes are almost exclusively attributable to driver error and are not likely to have been caused by the lane reduction on Buttles Street.
