Why this corridor sits in Tier 2

Stretching from Westwood through Beverly Hills and Miracle Mile into Koreatown, Wilshire Boulevard combines gentle horizontal bends near San Vicente and La Cienega with intense multimodal conflict density. Historical CCRS crash records show recurring left-turn opposing-through collisions, transit-lane merges, and dusk westward solar glare.

Key roadway traits

Protected vs. permissive left turns
Peak-hour transit lane rules

Methodology & interpretation limits

Complexity Index combines horizontal curvature, sustained elevation grade, speed-transition demand, and 12-month historical reported crash concentration per corridor mile. Counts describe observational public records unadjusted for daily traffic volume and do not represent driving safety advice. Missing-coordinate collision records in surrounding cities are reported separately in live buffered queries and are never plotted at synthetic coordinates.
