Wha hat t is a is a local local road saf oad safety plan ety plan? A data-driven, analysis and prioritization of an agency’s roadways for traffic safety, based on the top crash type(s). 2

Loca Local r l road saf oad safety plan ety plans in s in Washingt ashington S on Sta tate te  57 known plans  33 counties  24 cities  More agencies working on plans 3

Why hy use a local use a local road saf oad safety ety plan? plan?  To help understand traffic safety issues and determine safety priorities.  To help prioritize projects and be ready for funding.  To create a more context-based safety program to better address safety and spend limited funds.

Highw ay Safety Improvement Program (funding through WSDOT)  Purpose: Use local road safety plans to identify safety issues. Use engineering countermeasures to reduce fatal and serious injury crashes to help achieve Target Zero.  Estimated funds : $25 million/yr. in federal HSIP funds.  Examples : Road diets; evaluate & replace signs, pavement markings, & guardrail; slope flattening; lighting; enhance pedestrian crossings; roundabouts; signal timing and visibility improvements; high friction surface treatment. Data collection for systemic projects.  http://www.wsdot.wa.gov/LocalPrograms/Traffic/FedSafety.htm 6

County Safety Program  Call for projects: Opened 2/15/19, and the beginning of future odd numbered years: http://www.wsdot.wa.gov/localprograms/traffic/2019- county-safety-program-call-projects  Applications due : 5/31/19  Awards : October 2019  Match for preliminary engineering and right of way phases : 10%  Match for construction phase : None if funds authorized by 4/30/21. 7

City Safety Program  Call for projects : Opens 11/1/19 and the end of future odd numbered years:  Applications due : 3/6/20  Awards : Sept.-Oct. 2019  Subprograms :  Spot location (improvements at specific location(s) based on crash history)  Systemic (improvements at widespread locations based on the top crash type(s))  Match for preliminary engineering and right of way phases : 10%  Match for construction phase : None if funds authorized by 4/30/21. 8

2018 sur 2018 survey ey on local r on local road oad saf safety plans ety plans  Sent to : 51 cities & counties with local road safety plans submitted in 2017 and 2018.  Responded : 16 agencies (31%)  Number of weeks to create 3 a plan (including training) : 25% 1 37% 2 38% 9

2018 sur 2018 survey: ey: Usefulness of Usefulness of local r local road saf oad safety plans ety plans All 16 agencies said this effort was useful for identifying safety priorities:  69% very useful  31% somewhat useful  0% not useful Wikipedia.org 10

2018 sur 2018 survey: ey: Usefulnes Usefulness s of of local local road saf oad safety plan ety plans  “forced (us) to dig into the data” and “identify trends and high crash locations.”  “reveal(ed) collision patterns that had previously gone unnoticed.”  “has identified areas where we lack good information.”  “helped staff and our advisory committee focus on (the) highest (priorities).”  Was “useful…for summarizing and raising awareness of safety issues…and providing justification for existing programs/projects.”  Was “very helpful in prioritizing projects and determin(ing) (grants to apply for).”  Was “an opportunity to develop a basic policy and guidebook (for) designing safer transportation facilities going forward.”  Was “very helpful in evaluating our own program and how it fit (into roadway safety).” 11
