The Masivo Integrado de Occidente ('Western Mass Integrated'), also referred to as MIO, is a bus rapid transit system that serves Santiago de Cali, Colombia. The system is operated through articulated buses which move in dedicated lanes. Approximately 97% of the city's spatial perimeter will be covered by this system, involving nearly 243 kilometers. The MIO will cover approximately 72% of Cali's public transportation needs. The project was set in motion by an investment of US$405 million; with 70% contributed by the Colombian government and the remaining 30% by the municipality of Cali. These resources are destined to finance MIO's infrastructure: construction of trunks, fueling stations, rest stops, the system of stations, pedestrian bridges, terminals, and yards. The articulated buses have a capacity of 160 passengers and circulate exclusively on the trunks; in turn, the register type buses will transport between 80 and 100 people and they will travel through tramways and special diversions. The regular operation of the system is roughly from 5:00am to 11:00pm on weekdays and Saturdays, and from 6:00am to 10:00pm on Sundays and holidays.

Zoning

For better efficiency in the division of the system's routes, the Metrocali company developed a city zoning model following the example of the TransMilenio system. However, Metrocali did not assign letters to the trunk lines, but rather divided the entire city into different zones, giving each one a number, which are the following:

Stations

The MIO has several Trunk corridors which have stop stations where users can transfer from one route to another to reach their destination. The stations are listed from North to South and are classified in their corresponding zones.
