Multimodal PackagesNew Bikeshare StationsThe benefit analysis of new bikeshare station relies on a methodology developed by theMetropolitan Washington Council of Governments (MWCOG) for inclusion in a TransportationInvestment Generating Economic Recovery (TIGER) Grant application (TIGER II) for newCapital Bikeshare stations. The MWCOG methodology is based on the following assumptions:Each bicycle will be used six times per day – with increases by five percent a year as systemexpands (based on systemwide averages);Each rider will make two trips (one roundtrip); andRidership will increase 2.5 percent a year based on expansion.In applying the MWCOG methodology, benefits for bikeshare usage were calculated based onthe following assumptions:User Cost Savings – Change in per-mile user cost savings based on mode shift.Assumptions include average trip length (Household Travel Survey 2007/2008), vehicleoperating costs (fuel costs, maintenance, repair, tire costs, and capital depreciation), averagetransit fares (average rail versus bus trips, SmarTrip® usage, and fares), average taxi fares;and bicycle fees.Travel Time Savings – Measures the time savings for bicycle trip shifted from anothersource. Assumptions include mode shifts, average trip length, average speed by mode,value of time. All assumptions from National Highway Transportation SafetyAdministration (NHTSA) dataIncreased Access – A perceived benefit from trips taken that previously were not possibleor worth the time or cost.Congestion Reduction – Calculated benefit based on VMT reduction caused by increasedbikeshare usage and a corresponding congestion reduction value.Emissions Reduction – Calculated benefit from reductions in VOC’s, Nitrogen Dioxide,and CO2. Data is generated by MWCOG.Improved Public Health – Calculated benefit from improved public health due to increasedexercise caused by bicycling. Assumptions include health care cost increase for peoplecompleting 30 minutes of daily exercise versus those that currently do not ($20 per year),the percent of those bicycling or walking who do not meet activity recommendations (conservativelyassumed to be 20 percent), and the average extra exercise time needed to meetthe requirement (15 minutes).Accident Reduction – Benefit calculation assuming that with VMT reduction, the risk ofexposure decreases. Data is sourced from NHTSA.I-66 Multimodal Study 3-87
