Outline
• Define Customer Oriented Measures• Illustrate Customer Oriented Measures• Address Improvements• Describe New Measures
3
Customer PerspectivesQuality of Service MeasuresTransit Attractiveness
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

Stop Based Service Coverage
