The LRT(light rail transit) system, which has medium transport capacity between subway and bus is an advanced transportation system. It has many benefits like chap construction and operational cost down through driverless and flexible route planning. The rubber tired AGT(K-AGT) is a kind of LRT, which has rubber wheels and side guides. The side guides has many advantages, but brings vibration and noise problems from the friction between the guide rail and the wheels. This is the major source for the of passengers' discomfort. The purpose of this paper is to analyze dynamic characteries and running stability of the rubber tired AGT localization bogie if the AGT's speed is increased from 70 km/h to 80 km/h. The current design parameters of bogie suspension, as it is designed, was examined to satisfy the comfort index of the railway vehicle in performance test.

The Light Rail Transit (LRT) System which has medium transport capacity between subway and bus(5,000-25,000 persons per hour) is the most advanced transportation system. It has many benefits, cheap construction, operational costs through driverless and flexible route planning. Also, the rubber tired AGT (K-AGT) of various LRT has a rubber wheels and side guide. The side guide type has an many advantages. but occur a vibration and friction noise through contact between guide rail and wheel. Most of point that decreased comport is vibration thorough the guide contact. In this paper, It is purpose to improve the maximum running speed of rubber tired AGT localization bogie which is currently developed from 70km/h to 80km/h. To satisfy comport index of railway vehicle that is required in performance test. we examined coefficient of bogie suspension which is designed.
