Abstract:Urban public transportation operation scheduling optimization is an important content of the bus optimization, with the loss of the road network reliability and bus passenger flow volatility increases, as well as occurred in the use of public transport in an emergency, ensuring the public transport system can still run better, guarantee the survival state of the public transport system, and is the guarantee bus system reliability and the public transport system service level of a major breakthrough. This paper introduce the linkage scheduling to the driver and transit vehicle scheduling, considering the passenger mutations, traffic conditions, traffic congestion, traffic accidents, and many factors such as the driver condition, will the driver and the linkage of the bus scheduling combined with real-time scheduling, on the basis of the survival of decision on the basis of the above factors the pilot and the system bus scheduling model is established, through the analysis of relevant indicators to judge the survival state of the system. The results indicates that the method is of great significance to the scheduling of public transportation system.
