МОДЕЛЮВАННЯ РУХУ АВТОБУСА НА МАРШРУТІ МЕТРОБУСА

Abstract

The paper proposes to model bus movement on metrobus route using driving cycles. Object of the study – bus traction-speed properties and fuel efficiency. Purpose of the study – model bus movement on metrobus route using driving cycles. Method of the study – analytical, mathematical modeling. Mathematical modeling can be used to assess metrobus system effectiveness, selection and justification of its rolling stock. It allows at the design stage determine performance properties of individual bus or metrobus system as a whole. Bus movement on metrobus route was proposed to model by using driving cycle, which reflects real operating conditions. It consists of successive sections, which include acceleration, movement with constant speed, braking and engine idle. Metrobus route Miloslavska St. – Pochayna metro station was chosen. It has 13 stops and 12 section. Each section of the route is simulated using a section of driving cycle one of two types and includes five different phases of movement. Driving cycle and mathematical model built on its basis allows to determine parameters of bus traction-speed properties and fuel efficiency (travel time, average speed and fuel consumption).
