Optimizing the Time Costs of Passenger Transport of People With Disabilities

Abstract

The paper dwells on a mathematical model of the logistical system of transport services for persons with disabilities, and there have been analyzed factors that affect the time spent on their transportation. When developing methodology for optimizing the time costs of passenger transport of persons with disabilities, the following two basic transportation services have been taken into account: (a) "social taxi", which will transport only people with special health; (b) a vehicle system in combination with urban passenger transport, which will transport representatives of the group of people with restricted mobility together with all other passengers. The study found that in the case of insufficient accessibility to the required environment, by the increase in the demand of disabled people for transportation by "social taxi", travelling costs are increased that results in increasing total costs of the carrier. Based on a comparative analysis of logistical costs, optimum relationship between the number of the adapted buses and "social taxi" on the route under study has been established.
