Abstract
In the literature it has been proven several times, that the common driving cycles are not accurate enough to estimate the fuel and energy consumption data or emission data for vehicles, especially for public transport vehicles, such as buses. One can find driving cycles for buses, but the special driving environment in Debrecen, Hungary cannot be accurately represented by them. As a part of a project focusing on the determination of fuel and energy consumption of vehicles by dynamic simulation, a study has been carried out for determining driving cycles, which are representative for Debrecen. In this paper the development of a driving cycle for city buses in Debrecen is presented. Typical bus routes were selected in the town for the study, the vehicles were instrumented with an appropriate data collecting system. These onboard units were used to collect data such as travelled distance, speed and acceleration on several vehicles in the real-world traffic. We used special purpose software to pre-process and filter the collected data. After pre-processing a statistical evaluation of the data was carried out. Using a version of the widely spread micro-trip method of driving cycle development, a Bus Driving Cycle has been constructed for Debrecen.

Summary
In the literature one can find several different methods for driving cycle development. Most of these methods are based on statistical procedures applied on real-traffic data. Depending on the statistical method, on the considered characteristic parameters and on some other factors, different driving cycles can be developed for the same route (Huertas et al, 2019). The question is which procedure gives the optimal result regarding the representativeness of the driving cycle. It can be stated that the development procedure of the optimal driving cycle depends, among others, on the purpose of the driving cycle, and on the quantity and quality of the data available. The goal of this paper is to develop a representative driving cycle for city buses in Debrecen. To find the most representative one, several driving cycles were prepared using different clustering parameters and different strategies of micro-trip selection and were compared on the basis of different characterizing parameters
