11 Strategy Analysis by Mode 11 of 26 Strategy Analysis

12 Strategy Analysis - Cars: Parking: Currently: 4 lots with 503 stalls MTC and this thesis: 8 more lots with 1341 stalls BART parking 12 of 26 Strategy Analysis

13 Strategy Analysis - Cars: Ridesharing: Partner with TNCs for station access Vanpool/minibus apps (e.g. Chariot) Casual carpool apps (e.g. Scoop) Source: chariot.com 13 of 26 Strategy Analysis

14 Strategy Analysis - Cars: Carpooling: Enhanced casual carpooling Shifting attitudes on carpooling Increased enforcement Increased HOV patrols Citizen reporting Tolling: Electronic tolling at Bay Bridge Toll Plaza Eastbound tolling Bidirectional tolling Downtown San Francisco cordon Congestion pricing 14 of 26 Strategy Analysis

15 Strategy Analysis Buses/HOVs: Service expansions: AC Transit WestCAT Lynx Soltrans 200 Queue jumps: West Grand Avenue MacArthur Blvd Powell Street Source: MTC 15 of 26 Strategy Analysis

16 Strategy Analysis - BART: Improve train capacity (7, 8, or 9 car trains to 10) 15 cars = 1,050 seat capacity = 3,000 crush capacity Improve station capacity Alter service Skip-stop metro service Express service Source: AECOM 16 of 26 Strategy Analysis

17 Strategy Analysis - Planning: Change corporate cultures Promote telecommuting Reduce need for car at workplace Land-use planning Bring jobs to residents and residences to jobsites Transit-oriented development Long-term strategy, but needs to start now 17 of 26 Strategy Analysis
