Vision Zero Collision Geodatabase

Los Angeles County, Calif.

The Vision Zero Collision Geodatabase is a web-based application that utilizes GIS to map locations at which traffic collisions have occurred in the unincorporated County areas. Through this powerful tool, corridors experiencing the highest concentrations of collisions can now be readily identified on maps. Such visualization assists with determining the highest traffic safety needs in the unincorporated County areas and prioritizing resources to strategically implement safety enhancements. The Geodatabase was recently created by the County of Los Angeles Department of Public Works as part of the County’s newly launched Vision Zero initiative to reduce traffic-related deaths and severe injuries on roadways in the unincorporated areas. The new Geodatabase is capable of performing high level collision data analyses including the ability to run specific queries such as the most frequent types of violations (ie. speeding or D.U.I); age groups associated with certain collision types; modes of transportation (ie. pedestrians, bicycles, or vehicles); and communities most impacted. The County’s newly launched Vision Zero initiative utilizes a multi-disciplinary partnership among various agencies and stakeholders to comprehensively address traffic safety through engineering, enforcement, education, and evaluation strategies. The Geodatabase is essential in evaluating collision data, thereby targeting initiatives through a data-driven process.
