Abstract:

The focus of this research is to assess link-level transit performance measures using data captured through Automatic Vehicle Location (AVL) units installed on Charlotte Area Transit System (CATS) buses for year 2012. Query tools were developed to compute link-level transit system performance measures, conduct analysis, and derive meaningful interpretations. The link-level transit system performance measures were computed by comparing actual bus travel time along selected links (between two consecutive fixed bus stops) with the scheduled-travel-time along the same link for each run in the year. Actual delay time and early arrivals as well as percentage of times delay and early arrival was observed were computed to assist in the assessment. New level-of-service (LOS) criteria, to indicate link-level transit system performance, based on percentage-based measure are proposed. The analysis was conducted by time-of-the-day and day-type (weekday or weekend), for both travel directions, along selected transit segments to assist in assessing the applicability of the measures. Findings from the research indicate that percentage-based performance measures would be more reliable than fixed range-based measures (delay or difference in travel time) for planning and assessment of operational performance by transit system operators.
