This paper investigates both the vehicle and customer traffic to and from hotels. The study is divided into two main categories : size of hotels, and days of the week. Data samples are from 15 Hat Yai hotels comprising 5 big hotels (more than 200 rooms), 5 medium hotels (100-200 rooms), and 5 small hotels (less than 100 rooms). Field data are collected from all hotels on one typical work-ing day between 06.00-03.00 hr; and for only five hotels in one weekend day. Variables considered are type of vehicles; sex and age of customers; day, time, direction of the traffic; and service area, size of hotels, room tariff, and distance from center of business distric of Hat Yai.
According to size of hotels, the results show that vehicle traffic for the big hotels is larger than other hotel sizes with a 45.73% of all hotel vehicle traffic. On the vehicle type, motorcycles account for 29.37% of big-hotel vehicle-traffic, 36.67% of medium-hotel traffic, and 39.17% of small-hotel traffic. For customer traffic, big hotels take the most customers at the level of 57.88% of all hotel customers. On the vehicle occupancy, the figures are 2.09, 1.79 and 2.03 persons per vehicle for big, medium and small hotels, respectively. For the mean of travel, customers prefer the walking mean at 47.00% for big, 27.21% for medium, 13.63% for small hotels. The most prevalent modes are walking at 47.00% for the big hotels, and 27.21% for the medium hotels, but on motorcycles at 26.18% for the small hotels.
According to days of the week, the outcomes show that vehicle traffic on a weekend day is more than that of a weekday. The weekend volume is 59.68% of the total five hotel, two day volume. For the vehicle type, motorcycles are used more often than others : 30.63% on a weekend day and 35.29% on a weekday. Customers utilize hotels more on the weekend -- 70.14% of the total hotel customers. The vehicle occupancy stands at 2.05 persons per vehicle for the weekend and 1.85 for the weekday. The portion of walking customers are 36.88% of the total customers for the weekend, and 10.87% for the week day. The most prevalent mean to entering and leaving the hotels are on foot 36.88% for the weekend traffic, and by pick-up truck 26.88% for the weekday traffic.
For the relationship between person trips and vehicle trips into and out of the hotels and hotel variables, it was found that the number of rooms influences more on the person trips, while the number of hotel workers influences more on the vehicle trips. The hotel variables can explained the generated trips from 67% to 84%.
