Initial trip reduction achievement by three commuter groups in the Maricopa County Regional Travel Reduction Program for metropolitan Phoenix, Arizona, is reported. Although students had the most success in changing their behavior, non-school employees, by far the largest commuter group, and school employees also reduced their percentages of single occupant vehicle trips. Total reductions in single occupant vehicle miles traveled were small but measurable. Although economic subsidies as well as less expensive measures were linked with trip reduction at non-school work sites, education measures were linked with trip reduction at school sites. These findings confirm that early progress can be expected from regional employer-based trip reduction programs, indicate the need to consider different commuter groups, and affirm the value of diverse trip reduction measures. |
