Transportation Planning Board

TDM/Rideshare

The Madison Area TPB administers the Rideshare Etc. program, working in partnershipwith Metro Transit, the State Vanpool Program, Dane County, City of Madison, UW-Madison, and other public and private employers throughout the area. The program serves commuters in a 48-county area of central and southern Wisconsin and northern Illinois. The goal of the program is to reduce congestion and pollution and to help provide commuters travel options and personal transportation cost savings

The number of new commutters had increased by 98% from 2006 to 2008 with the large increase in gas prices, but the 2009 number represented a 27% drop from 2008. Assuming that 30% (a nationally accepted average) of the new commuter registrants with successful carpool matches actually result in ridesharing arrangements, the regional benefits of the ridesharing matches made by the Rideshare Etc. Program in 2010 are as follows:

• 34,905,331 fewer vehicle miles traveled (VMT)
• $17,452,586 fewer dollars spent on personal commuting costs
• 3,080 fewer required parking spaces
• 399.3 fewer tons of carbon monoxide pollution
• 56.1 fewer tons of volatile organic compounds pollution
• 87.7 fewer tons of nitrogen oxides pollution

The number of commuters in the Madison Metro Area active in the Rideshare, Etc. program is much larger than the number of new commuters registered each year as some commuters keep their registrations active for many years. Notably, this database of “active commuters” includes not only persons interested in carpooling but also those interested in van pooling, transit and commuting by bicycle. Moreover, ridesharing arrangements are also formed outside the formal Rideshare Etc. program, which are not tallied. According to recent Census data, around 33,000 Dane County commuters car/vanpool to work.
