4

Customer Oriented Measures

• Where and When of Transit • Hours of Service• Frequency• Service Coverage• System Wide

5

System Performance

• Weekday Span of Service– 18 hours +

• Frequency– Headway– Buses per hour

• Coverage– ¼ Mile Buffer

6

Improved Measures

• Customer Perspective• Stop or Neighborhood Level• Evaluate both ends of the trip

7

Driving Improvements

• Role of New Data• Role of New GIS Techniques• Computer Power

8

GIS Ideal Tool

• Illustrate Availability• Evaluate Availability
