In order to upgrade the service quality and standard in the metropolitan area, the government usually takes mass transportation systems into consideration. Characteristics of such systems include exclusive land rights, high capacities, high frequencies, high speed, and good service standards. Smaller cities usually cannot afford such systems because of the large construction and operation costs, especially now that the government is in an unstable financial situation. The Bus Rapid Transit System has many benefits and is less expensive than the Light Trail Transit System. Therefore, the Bus Rapid Transit System is becoming more popular in the international arena by satisfying the public transportation demand. There is only one Bus Rapid Transit System in the country, which connects Chia-Yi and the High Speed Rail station in Tai-boo. However, it has encountered many hardships during the implementation process. Our research tries to determine the suitable qualifications and conditions that could serve as reference during the construction period. Our research adapts city-type and shuttle-type system, which are more specifically divided into simple-type and full-type systems. However, all basic-systems belong to the corridor system condition. Furthermore, the suitable corridor conditions and characteristics for the Bus Rapid Transit System include corridor length, development process, and traffic service conditions. Under the circumstance in which revenue is able to balance the construction and operation costs, this research tries to evaluate the Bus Rapid Transit System model in the city-type and shuttle-type condition. The relationship between the different corridor lengths and their respective revenues is analyzed. We are interested in whether the revenue is larger than or equal to the cost rate and capacity combination. Finally, our research also takes into consideration the impacts caused by subsidies. Form conclusions, we can know that with same bus rapid transit system type without subsidies condition, taking city-type for example, when the road length is 5km, the traffic capacity on 0.9, 1.0, 1.1 times of the price, the demand requires 3482、2921、2612 people individually. And when the road length ups to 15km , the demand requires 26717、17278、13414 people individually. As a result, we can see when the length is longer, the traffic demand and price is higher. In addition, with the same situation with subsidies, when the road length is 5km, the traffic capacity on 0.9, 1.0, 1.1 times of the price, the demand requires 549、519、472 people individually. From above mention, we can get conclusions that the require condition will lower the demand when there is subsidies existing. Therefore, we can say that subsidies have impacted in bus rapid transit system obviously.
