摘要：	Bus transit routing schemes are analyzed for riders outside a major transit corridor. Two routing schemes are considered--no zigzagging and zigzagging. In the no-zigzagging scheme, the route runs along a demand corridor without detouring to pick up outlying riders, who must first access the corridor to be picked up. In the zigzagging scheme, the bus detours to pick up distant riders and then returns to the corridor to continue on to the final destination. Analytical cost models for no-zigzagging and zigzagging bus routing schemes are developed. Solutions for zigzagging conditions are derived, and some important concepts, practical implications, and useful results are presented through some simplifications. Also, a practical analysis of several access modes is presented. Depending on the location and number of out-of-corridor passengers, zigzagging can be an efficient routing scheme. Zigzagging is especially efficient in the outlying ridership areas if the number of passengers already on board is low compared with the number of outlying passengers requesting corridor service.
