Supporters of bus rapid transit made a renewed push for the system Tuesday night, undeterred by a November vote that left the proposal without a clear path forward for local funding.A group of citizens presented the C-Tran Board of Directors with more than 250 signatures in support of bringing the enhanced bus system to Vancouver’s Fourth Plain corridor. They also brought the endorsements of a handful of neighborhood associations, and a series of requests they say would move the concept forward.The group asked C-Tran to use its own resources, without raising taxes, to pay the local share of the project. Supporters also want to keep the concept from being lumped together with the Columbia River Crossing — a connection that has prevented bus rapid transit from gaining the traction it would find on its own, they said.“People there want this,” said Mark Maggiora, who leads the Vancouver-based nonprofit Americans Building Community. “We can do it without raising taxes.”C-Tran has said a bus rapid transit system would cost less to operate and maintain each year than the No. 4 and No. 44 routes that now serve Fourth Plain. Those savingscould reimburse any up-front cost to build it, Maggiora and others said Tuesday night.C-Tran first floated the bus rapid transit proposal in 2011. The enhanced bus system works by using larger vehicles, raised boarding platforms, specialized signals and other features in an effort to move passengers more efficiently and reliably.
