Select Focus Areas for Select Focus Areas for Enforcement and EducationEnforcement and Education• Red Light Running: Council interest in red light
enforcement and resident concern• Speeding: Resident concern and relation to red light
running• Pedestrian and Bicyclist Safety: #1 fatality
32City of Chula Vista – Traffic Intervention
Red Light RunningRed Light Running• According to FHWA
– Primary cause of collisions: red light running– 218,000 red light running collisions per year– 181,000 injuries resulting in 880 fatalities– $14 billion in economic loss
• Chula Vista Data (500+ residents surveyed)– 86% concerned about red light running (RLR)– 51% witnessed RLR more than once/week– 65% residents supported red light cameras

33City of Chula Vista – Traffic Intervention
Enforcement FrameworkEnforcement Framework• Target intersections with a high number of red-light collisions
• But do it randomly – Queensland Australia study: random enforcement reduced crashes
by 11%)• UK Model
– Sign boards for up to a week before and a week after
• Highly visible officers, different durations at least one hour Toronto, Canada study: no matter the duration, effects diminish rapidly once officers leave-one half after 10 hours, all after 6 days. If enforcement repeated during peak traffic hour, then 16% reduction in violations. +17% with an additional hour of enforcement.
34City of Chula Vista – Traffic Intervention
Red Light RunningRed Light RunningEnforcement StrategyEnforcement Strategy• Sign board warnings before
enforcement• Intensive officer enforcement at
targeted intersections (brochure distribution)
• Department-wide effort: Traffic, Patrol, School Resource Officers– 13 Friday projects by Patrol
• Recognition of officer efforts

““Stop on RedStop on Red”” OutreachOutreach• More comprehensive than ever• Challenging “Get the other guy, not
me…”• Single message: safety• Kick-Off News Conference

Enforcement FrameworkEnforcement Framework
• Deploy during hours of greatest crash risk on an unpredictable weekly schedule
• Traffic reporters, website pre-announce (DUI model). Digital signs the week of
• Maximize the visibility of the police presence
• Emphasize speed enforcement in all routine patrols.
• Select four enforcement zones based on crash records (several blocks to a mile or so in length)
• Select two zones based on citizen complaints• Plan on about 200 hours per month (8.5 officer hrs per week) for at
least six months

Process FrameworkProcess Framework• Step 1: Analyze the problem (stats, collision
data, etc.) and thorough internet research and benchmarking (5 E’s)
• Step 2: Baseline measurement (field data and survey data) and field engineering analysis
• Step 3: Develop specific enforcement strategy and tactics
• Step 4: Develop public education and outreach (consider incentives)
• Step 5: Launch• Step 6: Post measurement

““Stop on RedStop on Red””ResultsResults• Four month campaign• 72% citizens saw banners, 77%
saw bumper stickers, 78% saw brochures
• 795 citations for red light running (244% increase over last year)
• Red light running accidents decreased by 11%
• 27% drop in red light injury collisions (1st quarter 2006 vs. 1st
quarter 2007)• 19% drop in citywide collisions
reported

““Slow Down, Chula Vista!Slow Down, Chula Vista!””ResultsResults• Currently underway• Anecdotal:
– Residents report behavior change– Complaints that we need to get
cars to speed up
• First real data check last week– 16 segments, only three showing
any reduction in speed
• Need to re-evaluate enforcement deployment and outreach strategy

Safe Route to School GrantSafe Route to School Grant• Walking Audits for 3 elementary Schools• Community involvement • $1.5million for ped friendly improvements
– Takes time and adequate staffing commitment– Consider Phase I and Phase II approach
• Major Intersection Safety– Find a champion in PD; need a strong partnership– Be ready for the effort it takes to do the outreach– True integration of engineering, enforcement, education– Don’t miss your baseline measurement opportunities
• Ped and Bike Safety– System approach versus individual tasks– Consider wrapping in missing infrastructure – Leverage partnerships (community, schools and peds) for
grant $
