Lytvyn V. Substantiation of rational parameters of express mode of transportation in terms of local bus routes

The thesis deals with the topical scientific task concerning substantiation of rational parameters of express mode of transportation in terms of local bus routes. The research results are of considerable importance to organize transportation processes and make it possible to increase the efficiency of solutions for planning transportation services for passengers by selecting rational traffic patterns. That helps reduce passengers’ time spent for travelling, increase a degree of use of transportation modes as well as favour significant cost reduction for fuel and decrease the amount of harmful emissions in the urban atmosphere. Analysis of the available methods and approaches to the organization of express mode of bus traffic in terms of local routes has helped identified that they do not consider to the full extent the interests of all the traffic participants or have narrow range of application. Those are the facts that limit considerably wide implementation of express mode irrespective of its great potential as for increasing the efficiency of local passenger transportation. The developed model for assessing energy-efficient effectiveness of bus operation takes into account the effect of their traffic condition. It has been specified that fuel consumption during a route depending on the number of stops per 1 km of the route varied according to linear dependence. It has been determined that implementation of express connection on route will help increase energy-efficient effectiveness by 20-40%. Conditions of expedient implementation of express mode of transportation for buses on local routes have been identified basing on the parameters of passenger flow. To perform quantitative substantiation of the expediency of the organization of corresponding traffic patterns on certain routes, normalized coefficients of passenger variability and irregularity of passenger flow in terms of route shares have been proposed. A structure of criteria and system of limitations while implementing the express traffic pattern for buses take into consideration the interests of both a carrier and its passengers from the viewpoint of increasing transportation capacity of the route and decreasing overall passengers’ costs for travel. The developed method of the formation of a list of stops to be serviced by buses operating in the express mode, takes into consideration the irregular nature of passenger flow and intervals of daily bus traffic respectively. The developed methodology for calculating technical and operational indices of bus functioning while implementing the express mode of transportation takes into account redistribution of passenger correspondences between the standard and express modes of transportation basing on formalization of the time spent for a passenger’s trips depending on a list of express bus stops and number of buses on the route. The proposed complex parameter of the evaluation of efficiency of express mode use on local routes allows selecting rational parameters of a transportation process relying on the value of transportation operation, degree of bus occupancy, and passengers’ time spent for their travel. Basing on the economic, social, and environmental indices of efficiency of a transportation process, the developed method of identifying rational parameters of express mode of traffic on local bus routes considers dynamic distribution of passenger correspondences between the standard and express route depending on the number of buses and a list of express route stops. The elaborated method for evaluating the effect of traffic modes of local buses on the rules of formation of transportation demand takes into consideration technological features of passenger transportation processes and helps identify interrelations between the tariff value and traffic mode of buses as a function from the number of stops on the route.
