Summary Information
Field measurements were collected from April 1998 to May 2000 in order to evaluate the technical performance of each system in terms of service accessibility, travel times, punctuality, and regularity. The evaluation was conducted using records of in-vehicle data, interviews, surveys, simulations, and a representative test ride observations before and after system deployment.
FINDINGS
Ridership
The field study showed the system had positive effects on the level-of-service for each mode of transportation. Overall, the improvements in bus line performance were greater than those for the tramline since the tramline had signal priority in operation prior to field testing.
Based on a cross-section of test ride observations, in-vehicle studies, and ticket sales information; the pilot project increased the number of tram passengers by 0 to 2 percent, and increased the number of bus passengers by 10 to 12 percent.
Customer Satisfaction Personal Interviews
Approximately half of the persons interviewed used the line daily or almost daily. Seventy-one (71) percent of the tram passengers and 83 percent of the bus passengers noticed the traveler information displays. The displays were regarded as useful by 66 percent of the tram passengers and 78 percent of the bus passengers.
