Here is a really good interview (via capntransit) with the executive director that runs an aging multi-model system.
“People, operators, those types of folks. Everyone recognizes that it’s been 30 years and a lot of things have changed in that 30-year time frame technology-wise, origins and destinations, travel patterns. Our ridership has changed in 30 years.
“And particularly in this city, a great deal more seniors, a great deal more disabled passengers. And our operation carries a lot of school trips for school-age children so what happens in our particular case with the special events and all the different services we provide, in the 30-year time frame, a lot of things have changed.”
Ford says the TEP was a top-to-bottom analysis of the system to not only deal with OTP issues, but also travel times and to gauge customers’ needs.
What they found was that congestion, population increase, bicycle use — which accounts for nearly 20 percent of the travel share according to Ford — and pedestrians are all key factors.
