Summary of Case Study
Average distance to CBD: 24.3 miles Average peak weekday CBD bound riders: 726 Average # of inbound bus trips: 25 Typical headway in peak of peak: 3 minutes

Paired Analysis for OD Flows
Selected 2.5 mile radius around P&R Selected 1 mile radius to encompass CBD Tabulated OD volume between two sites,
by income bracket• $1,250 per month or less• $1,251 to $3,333 per month• More than $3,333 per month

Case Study Findings
Based on analysis of the 2.5 mile radius around case study METRO park & rides: Average weekday CBD bound riders: 767 Average LEHD worker flow to CBD: 1,579 Park & ride modal capture ratio: 18%• Lowest three sites 11%• Highest three sites 28%
