The cells highlighted in blue show the traffic on <br />the minor street for the same eight hours of the day. <br /> <br />Collision Data <br /> Three years of collision records were accessed in the Aries portal (January 1, <br />2020 – December 31, 2022). Ten crashes occurred at this intersection in this three -year <br />period. Nine of these crashes were right angle crashes. Six right angle crashes <br />occurred in 2020. Some of these right angle collisions were due to vehicles not stopping <br />at the stop sign on Sunnyside, some of them were related to drivers on Sunnyside <br />thinking that traffic on Colfax had a stop, and some of them were related to drivers on <br />Sunnyside not being able to see traffic on Colfax.This data exceeds the threshold for a <br />multi-way stop warrant, which is a minimum of five right angle collisions in a 12-month <br />period. <br /> <br />Other Considerations <br /> Optional criteria for an all-way stop include the need to control left turn conflicts, <br />high pedestrian volumes and vehicle/pedestrian conflicts, visibility conflicts, and two <br />similar residential neighborhood streets. <br /> There are trees along both sides of Colfax that make it difficult to see traffic on <br />Colfax while stopped at the stop signs on Sunnyside. Pedestrian counts were not done <br />at this intersection to determine if pedestrian volumes are high. However, this <br />intersection is in a residential area, in close proximity to a school, so there is a potential <br />for high pedestrian volumes. <br /> <br />Recommendation <br /> The traffic volume at the intersection does not warrant a multi-way stop. <br />However, the collision data does warrant a multi-way stop. Due to the number and <br />nature of the right-angle collisions, the site distance concerns at the intersection, and <br />the potential for high pedestrian traffic, the Engineering Division recommends the <br />installation of stop signs on Colfax Ave at the intersection with Sunnyside Ave to make <br />the intersection an all-way stop. <br /> In the implementation of these new stop signs, the Engineering Division <br />recommends the use of two flashing stop signs and message boards to alert drivers of <br />this change. These devices would be left in place for 90 days, then the message boards <br />will be removed and flashing stop signs will be replaced with regular stop signs.
