“ “PREVIOUS SUCCESSES” PREVIOUS SUCCESSES”  OLYMPIAD XXIII - 1984  Projections of Huge Traffic Jams /  Images of Stranded Tourists Missing Events  Residents “Scared” into Leaving Town Los Angeles Praised -“Great Planning!”  SAN FRANCISCO EARTHQUAKE - 1989  No Advance Warning  Motorists / Congestion Disappeared  Diversions Did Not Account for Total  “Where Did They All Go??” San Francisco Praised - “Great Work!” “People are Resilient AND Resourceful!”
STUDY PURPOSE STUDY PURPOSE  Evaluate District compliance with Guidelines  Evaluate Typical Measures of Effectiveness  Determine Most Effective Strategies  Evaluate Cost versus Benefit  Establish Lessons Learned  Formulate Recommendations to Improve TMP Process / Modify Guidelines
8 of 15 of the Most Congested Cities are in California Caltrans’ Mission Caltrans’ Mission “We must get the most out of the roads we have before building any new ones…..well, duh!” To Improve Mobility To Improve Mobility Across California Across California
DEPUTY DIRECTIVE 60 DEPUTY DIRECTIVE 60 (Eff. 2000) (Eff. 2000) WHAT’S THE POLICY? WHAT’S THE POLICY? Construction Special Events Encroachment Permits Maintenance Caltrans’ commitment is to: Minimize motorist delays for ALL activities on the State highway system without compromising public or worker safety, or the quality of the work being performed. ..but with Varying Levels of Treatment..
