Major Arterials
Major arterials account for over half ( 59 %) of all KAB crashes in Arlington . Major arterials tend to prioritize vehicle mobility , carry large volumes of traffic for longer distances , and serve both local and through traffic . In Arlington , major arterials have three to six vehicle travel lanes , and typically have a center median or center turn lane . The majority of KAB crashes on major arterials occur on four lane arterials ( 46 %) followed by six-lane arterials ( 35 %) with posted speeds of 40-45 mph ( 74 %). Additionally , over half ( 54 %) of KAB crashes that occur on major arterials are at signalized intersections . Some major arterials have sidewalks , while many have disconnected or no sidewalks , and lack bicycle facilities .
Near Schools
Nearly half ( 49 %) of all KAB crashes occur within a half mile of a school and represent a disproportionate share of pedestrian and bicycle related crashes . Pedestrian involved KAB crashes near schools accounted for nearly double the rate of pedestrian involved KAB crashes as those occurring further than a half mile from a school . Near schools , KAB crashes are occurring largely on two-lane roadways ( 45 %) and four-lane roadways ( 31 %). Further than a half mile from a school , two-lane roadways account for 23 % of KAB crashes , and four-lane roadways account for 51 % of KAB crashes . Two-lane roadways have lower posted speeds , and the data shows that KAB crashes near schools occur on roads with a 30-mph posted speed at twice the rate as roads with a posted speed of 30 mph further than a half mile from a school .
