Based on different land uses, the survey is individually conducted to estimate daily trips, peak-hour trips, peak-hour and daily trip distributions, rate of choosing mode, vehicle occupancy for different modes and so on. Also, the statistical estimation of trip generation rates has been separately calculated by mean value, maximum value, minimum value, and regression model, etc.

For residential communities, the number of households used as an independent variable is much more critical for estimation. According to the result of the research, trip generates three peak values and both rates of choosing modes for auto cars and motorcycles are 40% of total trips.

For golf courses, the number of holes is a suitable variable for trip estimation. The auto trips make up about 68% of total trips in this research. The value of auto trips is more magnified and peak period is more obvious for regular playing schedule.

For colleges, the different educational systems are properly classified before estimating trip generation. Since academic courses are selective, peak period of trip frequencies is not obvious and concentrated. As similar to the high schools, junior colleges have two significant peak periods during the morning and afternoon.

For recreation areas, trip estimation is considered by the area types. The size of areas is used as an important variable to estimate trip generation rates. The highest rate takes place in amusement parks. The second higher rate takes place in scenic parks and the lowest is in natural parks.

For industrial parks, the trip distribution is much similar to the commuter type. There are two peak periods during the morning and afternoon.

For warehouses, the peak period is during 8:00 p.m. and 9:00 p.m. The size of the warehouse is suggested as a basic variable for estimating trips. The distribution rate of trips by motorcycle on weekdays is 60% of total trips. Moreover, the rate of trips by auto on holidays is also 60%.
