Establishment of Typical Driving Patterns for Light-Duty Vehicles on Different Roads in Hsin-Chu Area of Taiwan

Abstract:

This study utilized the car chasing method to chase 86 light-duty vehicles on seven major roads in the Shin-Chu area and establish the typical driving patterns for various roads. The 23 parameters that associated with the driving were considered to elucidate the features of driving patterns. This work examined two manners, corrected Euclidean distance and traditional Euclidean distance methods, to elucidate a representative driven cycle. In the screening procedure of the typical driven cycle, factor analysis was applied to correct Euclidean distance and examine the 23 variables of driving conditions. The results indicated that the first five of the 23 principal components explained at least 94% of the variance for seven roads. The physical interpretation based on factor analysis was better than the traditional Euclidean distance method, so the results of factor analysis were used to select the typical driven cycle. The average speeds were 34.1 kmh^-1 for the city road; 36.8, 26.1 and 30.4 kmh^-1 for county roads 118, 120 and 122; 38.7 and 36.5 kmh^-1/ for provincial roads 1 and 3; 85.9 kmh^-1 for freeway.
