Identification method of potential public transportation lane demand based on bus line operation stability
Combing the existing public transportation lane design specifications around the world,it is concluded that the setting of bus lanes usually considers the peak hour road bus passenger volume of section,bus traffic volume of sections,road conditions and other objective indicators,with little consideration given to the operational stability of bus routes on the road and its influence of improving passengers'experience of bus service reliability.In the post-operation evaluation of the public transportation lanes,operational reliability and efficiency assessment are finished regularly.Due to the lack of conditions for setting up dedicated bus lanes,some dedicated bus lanes have poor operational effects and no improvement in passenger experience.Therefore,considering passenger experience,a potential public transportation lane demand identification method based on the stability of bus operation was proposed.Based on the actual road conditions and bus vehicle GPS data,the deviation of bus vehicles from the planned schedule on each road section or station was analyzed,and two indicators,namely the bus congestion index and bus delivery time volatility were constructed,to form a classification method based on bus operation stability of road sections or stations.The proposed method was applied to the roads of 69 bus routes in central Shanghai,and the identified roads with poor bus operation stability were considered as potential needs for public transportation lanes.The method can also target public transportation lanes that need further optimization and improvement.
