The system is jointly operated by 15 individual bus transit agencies, sharing the same fare structure, ticketing process, and route numbering.

The 15 agencies are: Fuho Bus (Chinese: 福和客運) was previously part of the system, but left in 2009.

Each bus operating agency participating in the joint alliance formed a committee overseeing a joint-venture management centre.

The alliance shares stops and waiting areas, and operates universal ticketing and fare structures.

All revenue generated is collected by the management center and is then distributed to individual operators to meet their expenditure needs.

Furthermore, Taipei City Traffic Bureau makes a bi-annual service quality evaluation of each operating agency.

After the lienying system was implemented, and in order to reduce the number of employees, ticket-punchers (conductors) were gradually phased out.

The subsequent decrease in the drivers' work efficiency then led to the scrapping of the "ticket-punching system" in the beginning of 1994; after which, customers paid upon boarding and leaving the bus.

[1] Later, the private bus companies and transport offices (民營業者與官方單位) made plans for a system where fares would be deducted from a "retained value chip" ticket.

Transfer points are located at such places as Shilin, Songshan, Gongguan, Yonghe, Wanhua, and Sanchong, or at the Taipei/New Taipei border on the Tamsui and Xindian Rivers.

The locations where the intersection points were designed have consistently become the best places for passengers to change buses, and due to increased pedestrian traffic in those areas, popular and energetic retail streets have developed.

As would be expected, riding through 10 more stops but not through an intersection point would only require the payment of "one-section route" fare, but to board the bus at an intersection point, and riding through only two or three stops, would require a "two-section route" fare.

Because the fares required were not proportional to the distance covered on the bus, buffer zones were then created.

Buffer zones were created as stations concentrated in areas before and after bridges and tunnels, (e.g. 自強隧道), which increased the efficiency of pedestrians transferring from one bus to another.

The bus companies and the Taipei City Transportation Bureau have different views regarding the adjustment of ticket prices: this inevitably leads to disputes.

For the convenience of residents living in suburban, mountain areas, smaller buses have been operated since 1979.

Small routes are usually run with 20-seat mini buses and were operated by the Taipei City Bus Administration.

For example: the "small route" of the S1 local bus (Neigou—MRT Kunyang Station originally only travelled to the area of the Xinnan Temple, Nangang Farmers' Association.

To service the disabled, Wheel chair users, the "Bo-ai bus" line was specially operated.

Taipei Metropolitan's other buses that stop at hospitals provide (Natural Gas Low bottom dish bus) at fixed intervals.

In 2001, Taipei City Bus Administration (now Metropolitan Transit Company) imported 30 low-floor buses from Hungary, which were assigned to routes 22, 41, 49, 63, 74, 222, 270, 277, 285, 287, 601, 606 and 630.

In 2008, with subsidies from the Taipei City Traffic Bureau, private operators started purchasing low-floor buses.

Xinyi New Trunk Line (信義新幹線), operated by Capital Bus (首都客運), as well as 72, 902, 220 and Brown 9, will all have low-floor buses.

In 2007, the Taipei City Traffic Bureau planned several Citizen Mini Bus routes, to provide the "last mile" shuttle needs from MRT stations to communities.
