Assumes 12,360 individual rideshare applicants in the eleven programs (based on actual data from past years). Vehicle trips reduced = 12,360 applicants * 0.24 formation rate = 3,000 vehicle trips reduced per day (assumes 24 percent of total applicants will take part in ridesharing each day). VMT reduced = 3,000 vehicle trips * 28 miles = 84,000 vehicle miles per day (assumes oneway trip is 14 miles).

NOTES: Assumptions regarding travel impacts seem very low. In particular, a 15% utilization rate means that on average only 7.5 of the 50 new spaces are utilized, and only about one person per day is assumed to reducing a vehicle trip. Also, the assumption of a 20 mile round trip (10 miles each way) for a park and ride trip sounds low, particularly given that the lots are located in Cecil County, about 20 miles from Wilmington, DE and from Aberdeen, MD, and 40 miles from closein Baltimore suburbs. In the CMAQ database, this project appears to have been improperly listed as in the Metropolitan Washington Council of Governments' MPO. Current Maryland State Highway Administration web site shows 25 spaces at I95 @ MD 279 (Elkton) lot and 17 spaces at I95 @ MD 272 (Elkton) lot.
