I have tracked and researched Travel Demand Management for nearly 10 years, and initiated a number of basic applications (eg Edinburgh Fringe Bus Pass package, input to Uni-Link scheme etc). Cornell's scheme initiated in 1990 indicated a nett saving of $3.6m in first 3 years on car park provision costs against free transit and scheme management, and UCLA found their recent car parking interest payments were 4 times greater than the 'income' per space. I'd like to catch up with some work done at UCLA by Prof's Donald C Shoup and Brian Taylor. Any contact details, or material available in UK/on www? Post any addresses personally to avoid excess list traffic - thanks. I'd be very interested in working concepts of TDM and the Portfolio of Travel Choice into a more tangible thesis or range of papers to match the awakening of institutions to the true costs of transport and benefits of an integrated approach.
