A HEAP of data….
…needs to be structured for MANAGEMENT decisions
When is a bus or train too crowded?
How do schedules account for variable traffic?
When and where should buses run more often?
How can street designs work better for transit?
Some Questions…
Service Standards
Systematic, comprehensive, predictable method to design, evaluate and adjust service
Balance ridership, cost, community needs to improve usefulness of our service to the public
Service Standards
Network Design Route structure and layout Policy headways Span of service Stop spacing
