An investigation of the bus headways and the passenger waiting time on the urban routes
Waiting time at stop for boarding in shuttle vehicles is most unwanted part of passenger transportation difficulty using public transport. The value of average waiting time at bus stop directly affects the degree of traveling satisfaction and is an indicator that determines the quality of transport services. The article made a statistical analysis of bus headway at stops, located at the joint area of several routes in the city Zaporozhye (Ukraine) during the period of morning peak hours. The presence of significant linear correlation between expectation of network headway of different groups of buses, each of which corresponds to the selection of passenger variant, and its standard deviation. It is established that the headway at bus stop for various groups of routes having inconsistent schedules with sufficient accuracy for practical calculations can be described by the law of the gamma distribution with shape parameter that, subject to the random passenger arrival at stop and equiprobable passenger distribution for groups of routes increases the average passenger waiting time at bus stop by 15-25 % in comparison with the case of regular bus traffic.
