The public transportation system is terrible that no one really uses it, especially off-peak. 2. Because there is no one really uses it, the Trimet company cuts of many bus supply, and it causes a vicious cycle. **Future Contribution:** Even though Portland is a large city with very low density of population, the population is glowing in a certain speed, and the existing public transportation system should not be wasted like that. The route should be changed to only connect to the central of downtown and the satellite cities with very cheap or free parking lots nearby. Hopefully, the public transportation system in Portland, Oregon will be changed in the future.
