Comparative Analysis of Separate BRT and All-in-One BRT Operating Scenarios for East Bay Bus Rapid Transit

This presentation compares two Bus Rapid Transit (BRT) operating plans for East Bay - Separate BRT and All-in-One BRT, evaluating factors like transit travel time, ridership, energy use, cost, and impacts on traffic. Helpful insights for the Policy Steering Committee's future decisions.

  1. East Bay Bus Rapid Transit presented toPolicy Steering Committee presented byAC Transit May 15, 2009

  2. Purpose • Understand two BRT operating plans considered in DEIS/DEIR • Explain reasoning for staff-preferred operating plan • Provide information to PSC members for future decision 2

  3. Two BRT Operating Scenarios 1) Separate BRT and Local Services • Two separate bus services in corridor • BRT in bus-only lanes with wide station spacing • 35 stations, average ½ mile (6 blocks) • Local service in mixed-flow traffic with narrow stop spacing • 105 stops, average 900 feet (2 blocks) 2) All-in-One (Combined BRT and Local Services) • A single bus service in the corridor • All buses in bus-only lanes • Intermediate station spacing • 49 stations, average 1/3rd mile (4 blocks) 3

  4. Key Issues for Comparison • Transit travel time • Transit ridership • Auto travel • Energy and greenhouse gases • Capital cost • Operating cost • Bicycle environment • Traffic impact • Parking impact • Walk access 4

  5. Comparison Summary Separate BRT and Local All-in-One Average Transit Travel Time + Transit Ridership + Auto Travel + Energy, Greenhouse Gases + Capital Cost + Operating Cost + Bicycle Environment + Traffic Impacts + Parking Impacts similar + Walk Access 5

  6. Effect on Travel Time*Downtown Berkeley to Bay Fair BART • “Separate” has fast BRT and a slow local bus • BRT: 59 minute • Local: 109 min • Average: 76 min • “All-in-One” on average faster than Separate • BRT: 66 min * Year 2025, PM peak 6

  7. Transit RidershipYear 2025 Separate BRT and Local All-in-One No-Build Corridor Transit Boardings 28,100 43,700 49,200 New Transit Trips* 9,300 5,300 * Increase over No-Build 7

  8. Auto TravelYear 2025 Separate BRT and Local All-in-One Reduction in Daily Auto Trips 5,300 9,300 Reduction in Daily Auto VMT* 11,800 20,700 * Vehicle Miles Travelled 8

  9. Energy and Greenhouse GasesYear 2025 Separate BRT and Local All-in-One Reduction in Annual Energy Usage 210,000 gallons* 50,000 gallons* Reduction in Annual GHGs 1,900 tons** 120 tons** * Annual Gasoline and gasoline equivalents ** Annual CO2 and CO2 equivalents 9

  10. Capital and Operating CostService Frequency (Weekday, Minutes Between Buses) Peak Midday Evening Owl Existing 1R 12 12 1 15 20 20 60 Separate BRT and Local BRT 7.5 7.5 20 1 15 15 20 60 All-in-One BRT 5 5 10 60 10

  11. Capital and Operating Cost$ millions Separate BRT and Local All-in-One No-Build Capital Cost $215 $235 $21.5 Annual Operating Cost* $25.6 $26.9 $15.0 Annual Operating Cost Net of Fare Revenue* $15.4 $18.2 * Estimate for year 2025 costs in 2008 dollars. 11

  12. Bicycle Environment • All-in-One provides better bicycle environment • Lower auto VMT • All buses operate in median bus lanes • No interference between buses and bicycles 12

  13. Traffic Impacts • All-in-One has less impact on traffic • Lower auto VMT • All buses operate in median bus lanes • No interference between buses and autos 13

  14. Parking Impacts • Two scenarios roughly equal • “Separate” requires both BRT Stations and Local Stops between Stations • Parking Loss at Stations • Parking restrictions remain in place at local bus stops • “All-in-One” has two effects on parking • More parking loss due to more BRT stations • Some parking spaces recovered at former local bus stops 14

  15. Effect on Walk Distance • Some local bus stops removed with All-in-One • 80% of riders unaffected • They walk to the same station as today • 20% of riders would need to go to a different station • Some passengers have no increase in walk distance • Some passengers walk further but, the walk distance is on average one additional block 15

  16. Effect on Walk Distance Existing Conditions Bus stop every 1/6th mile (900 feet) 16

  17. Effect on Walk Distance All-in-One BRT station every 1/3rd mile 17
