Driving Cycle in each country may be different under the influence of various parameters, one of them is the type of vehicles and driving behavior. In this project, it has been tried to investigate the effect of the vehicle type parameter on data collection and extraction of the driving cycle. For this purpose, four test routes that are representative of real conditions have been selected. Then the data collection of the driving behavior of the vehicles has been done. Data collection vehicles include Dena, Dena Plus, Hima S7, Pars and Prius. In this regard, data collection has been done for a period of three months and a duration of sixteen hours and thirty minutes and a distance of five hundred and seventy kilometers by means of a mobile application, along with geographical location data. Twelve characteristic parameters are considered to eva‎luate the data of various types of vehicles. In the following, with the method of principal component analysis or sensitivity analysis, the influencing characteristics are separated. Then, by using one of the big data analysis methods, such as the K-means method, it has been used to cluster the data. In the cycle construction level, the eva‎luation criteria are studied to select appropriate driving cycle. After creating the final cycle of vehicles, driving characteristic parameters have been calculated and verified by Chi square error and Root mean square error. The highest Chi square error value is 8.73 and the highest Root mean square error value is 3.66. Then, the comparison of the final cycle of vehicles with standard and research driving cycles has been investigated Finally, the effect of the vehicle type has been investigated in terms of different engines, gearboxes, turbocharger system and car class. The results show, compared to the standard cycles, the created cycles have been in the accelerated state for a longer period of time. Also, by examining the final cycle of each car, it was found that the hybrid car has a higher speed than the gasoline and dual-fuel car. Cars with CVT and automatic transmissions are also faster than cars with manual transmissions. Also, SUV class cars have more acceleration than C class cars. Then, the final driving cycle of the cars in the research was also created in the investigated routes and compared with the standard cycles and the cycles of each car. Studies show that the final driving cycle of the cars compared to the standard cycles and the cycles of each of the cars was less time moving at a constant speed.
