Transit headway deviation may result in loss of service capacity and excessive waiting times for passengers. This article presents empirical analyses results of bus route headway deviation through extensive data collection along the No. 19 bus line in Jiangyin City, China. Results indicate that link headway deviation and stop headway deviation, the two major contributors to route headway deviation, are negatively correlated and have opposite contributions to route headway deviation in most cases. Compared with stop headway deviation that is well accepted in literature to be the dominant contributor to route headway deviation, link headway deviation has shown greater contribution in both number of trips and percentage of contribution. Insights gained from the empirical analyses are critical for developing control schemes to prevent the amplification of route headway deviation at downstream stops, by properly adjusting link headway deviation or/and stop headway deviation to make them negatively correlated if possible.
