5. NextBus Sign Locations (Discussion/Action) James Lowé
James Lowé, Transit Planner, provided information on locations for the initial 400 NextBus installations. Signs were distributed throughout the city, based on geographic equality (approximately 35) in each of the Supervisor Districts, and where power was available. Most transit shelters are not electrified due to the cabling distances or the lack of a Pacific Gas and Electric metered connection. To establish power, the installation cost per shelter would be $10,000 - $30,000. If power were available, but no proper connection, the price for a new meter installation would be $5000 - $7000.
6. NextBus Signs Powered by Solar Cells and Electricity at Next Generation Bus Shelters (Discussion/ Action) Gail Stein
Gail Stein, Manager, Real Estate, reviewed plans for the Next Generation bus shelters. The Arts Commission has just approved the shelter design. Clear Channel has a year to install five proto-types. The new contract allows up to 1500 shelters, but it is probable that not all of these will be installed. Of the 1100 present shelters, approximately 410 have power. Clear Channel, the City Attorney's Office and the SFMTA are working to provide power for many, but not all, of the other locations. All new shelters will have photovoltaic cells to provide solar power for lighting; however the present NextBus Signs draw too much power to operate from these solar cells.
Mr. Lowé stated that because electricity is a major problem, other possibilities include locating the signs within private business windows or as stand-alone units.
7. Light Rail Vehicles on Market Street and the Eureka Portal rebuild (Discussion/ Action) John Byrd
John Byrd, Deputy Director for Rail Operations, presented a feasibility analysis of rewiring Market Street for emergency LRV operations. In-house estimates to accommodate pantographs would be $25 - $30 million dollars. This could be accomplished by staggering the wires, with the positive wire positioned lower than the negative. It would take approximately one year for construction, with an additional 6 months for the RFP and bid process.
Steve Ferrario said that in addition to providing emergency LRV street operation, rewiring could allow the opportunity to relocate one of the existing Metro lines onto Market Street. This would increase the available capacity for the remaining lines within the subway.
Mr. Byrd stated that the subway continues to be a major "pinch-point." Anything that could increase the passenger throughput would be welcomed. Mr. Byrd stated that he might try running the ATCS in manual to determine if that would make the operation faster.
As part of the rewiring, Mr. Byrd presented information on the usability and stability of the Eureka Portals. His research found that some height accommodations would be needed, but that the portals could be used with the present BREDA cars.
8. Committee Members’ Questions/Information Requests: (Discussion)
• Norm Rolfe asked about the power (voltage and current) requirements for the present NextBus signs. He also asked if the signs could operate on direct current and what would be the ampere-hours required for battery operation.
