This is a collection of all scripts related to the Vision Zero program in Los Angeles. A big thank you to @devmorris for getting us started here in Los Angeles. For an overview of how these scripts relate to Vision Zero work, see the paper here.

The purpose of this project was to identify candidate locations for new signals in the City of Los Angeles, based on safety warrant criteria outlined in the CA MUTCD.

For intersections that were already signalized, the purpose of this project was to idenfy candidate locations for protected left-turn signals, based on safety warrant criteria outlined in the CA MUTCD.

Beyond the specific warrant criteria, we extended the script capability to forecast the safety benefit of other safety engineering countermeasures, such as roadway reconfigurations.

This folder includes all the scripts that were used to help clean up the street centerline and intersection file provided by the Los Angeles Bureau of Engineering.
