The Oregon Department of Transportation tested a system to collect a vehicle-based mileage fee as a replacement for the Oregon gas tax. Preliminaryanalysis of the results for that experiment found that access to transit affected peopleÆs response to pricing. However, the measure used was a self-reported estimate of distance to ôthe nearest bus or rail stop that could take you places you want to go.ö Since this is not a commonly defined measure, household addresses were used to identify actual distance to transit services and various measures of transit service available. The measures of transit service available were not found to affect peopleÆs responseto the mileage charges, but actual distance to either any transit or to frequent transit service did have a statistically significant effect on thechanges in rush hour miles in response to the prices. There was also an effect on changes in total mileage, but it was not statistically significant.
