Title: Parking Charges + Incentives: Reduce Commuting VMT 23% TRB Transit IDEA Proposal



at work sites with free parking. Single occupancy vehicle (SOV) commuters are charged each day they park at the workplace. Commuters using alternatives (transit, vanpool, carpool, bike, walk, telework) are provided financial incentives funded by the SOV parking revenue. Implementation begins with $0.25 SOV daily parking charge and $0.50 commute alternative incentives. Charges and incentives are increased gradually to a final level of approximately $2.00 SOV parking charge and $4.00 incentives. Commute behavior changes gradually, reducing SOV mode share from 80 % to 57 % at suburban job sites. As a result, transit and carpooling mode shares increase substantially. For an employer, project implementation cost is very low, as employees self-report their commute choices on a web-based commute calendar that is periodically imported into payroll processing. Employers do not have to add parking access control. Some of the main arguments in favor of this IDEA concept • From a previous parking bill (SB518) introduced by California State Senator Lowenthal, "Eliminating subsidies for parking has enormous potential to reduce traffic congestion and greenhouse gas and other vehicle emissions by reducing vehicle miles traveled. If drivers must pay the true cost of parking, it will affect their choices on whether or not to drive. In the short term, changes to parking policy can reduce traffic congestion and greenhouse gas emissions more than all other strategies combined, and they are usually the most cost-effective." • Free solo driver workplace parking represents a perverse incentive to encourage solo commuting. The subsidy for free parking at suburban Bay Area (Pleasanton) workplace parking lots is $7.59 per day per solo driver. [Daily Parking Subsidy
