Similar <br />to previous lighting tables, there are more collisions in daylight hours, <br />likely due to more activity during the day. A large percentage of colli- <br />sions occur under street lights at night. <br />Chart 3-20 represents the movement of the automobile in the colli- <br />sion. As shown, vehicles proceeding straight have the highest rate of <br />automobile collisions followed by left and then right turns. Chart 3-21 <br />lists the primary collision factor showing unsafe speed as the most fre- <br />quent cause, auto right-of-way being violated, then signals and signs <br />violations, and then improper turning. Chart 3-22 lists the right-of-way <br />controls (signals and signs) with most automobile collisions occurring <br />where controls are present and functioning. <br />As shown in Figure 3-11 there are concentrations of vehicle collision in <br />the downtown area as well as the full length of primary vehicle corri- <br />dors like 1st Street, 17th Street, McFadden Avenue, Edinger Avenue and <br />Warner Avenue going east-west and Main Street, Flower Street, Bristol <br />Street, and Fairview Street going north-south. Areas near the following <br />intersections also show higher levels of automobile collisions: Warner <br />Avenue and Main Street, Warner Avenue and Bristol Street, Edinger <br />Avenue and Fairview Street. Collisions resulting in severe injuries and <br />fatalities tend to follow primary and major arterials, such as 1st Street, <br />17th Street, McFadden Avenue, Edinger Avenue, Warner Avenue, Dyer <br />Road, and going east-west. North-south corridors with higher levels of <br />severe injury and fatalities include Harbor Boulevard, Fairview Street, <br />Bristol Street, Main Street, Standard Avenue, and Grand Avenue. <br />Chart 3-19: Automobile Collisions by Day of Week <br />  <br />  <br />City Council 32 – 62 6/4/2024
