 [ABSTRACT]

This study aimed to derive implications on how usage characteristics vary depending on the characteristics of each region based on the results of call bus operation by township in Cheongju City and to propose a DRT operation plan that suits the characteristics of the region. DRT is expected to have different usage rates and usage characteristics depending on regional characteristics such as regional population, target area, residential distribution, industry, public transportation system, and traffic characteristics.

To this end, the regional characteristics of each township in Cheongju City were compared and analyzed through statistical data, and the traffic characteristics of each township were analyzed through the transportation system, mobile data, and the national transportation database. Cheongju City has different populations and land use, ranging from 2,000 to 70,000 people per township. Traffic characteristics also vary depending on the location of each township, requiring an appropriate transportation system.

We examined the status of DRT operation by region in Cheongju City and compared and analyzed the characteristics of DRT operation according to regional characteristics to derive the following implications. When setting up a service area, you can connect directly from the central city without DRT service, or if you form a single living area for each township, you can group adjacent townships together to set up a single service area. The method of using call-type DRT varies depending on age distribution, and an appropriate division of functions between call-type and fixed-type routes is required depending on the size of the area. The service scope should be set differently depending on the location of the traffic hub, and call-type and fixed routes should be appropriately utilized depending on whether there is fixed demand, such as industrial complexes and schools within the region. It is necessary to consider the transfer system with public transportation routes, and it is also necessary to review ways to adjust the service scope according to travel demand.

Based on the derived implications, directions for improving the existing DRT operation were suggested according to regional characteristics. In areas with poor DRT transport performance, improvement directions were suggested for issues with setting service areas and operating methods that do not match travel demand. As the location of the traffic center is biased to one side, the inefficiency of the call service is occurring, so an improvement direction was suggested to adjust the service scope. In areas where there is a mismatch between traffic demand and operating system, we suggested ways to adjust the service scope and fixed routes to meet traffic demand. A plan was proposed to meet peak hour commuting demand by expanding fixed routes rather than call-type services in areas with high peak hour demand. To address the problem of inefficiency caused by the fact that most passengers are only 1-2 at a time, a plan was proposed to concentrate demand by offering discounts on fares during specific time periods.

To establish a sustainable rural public transportation system, a direction for public transportation reform, including DRT, was presented. Before introducing DRT to other cities and counties, the existing public transportation system must first be reorganized into a trunk-branch public transportation system and a branch transportation system centered on towns and counties must be established. In constructing a local transportation system centered on towns and townships, the local transportation system was categorized based on the population distribution, service area, central location and characteristics, living area, and traffic characteristics of the town and township, and a plan for constructing a local transportation system and transfer system consisting of call-type DRT, fixed routes, and public taxis was presented.
