Light bus or taxi service to serve a town

I visited AMK Hub to buy some accessories for my home. Although it is a working day, the car park is full and there is a long queue of cars trying to get into the mall. I decided to keep the mall.

It does not make sense to drive a car, due to the high ERP and parking charges and difficulty to get a parking space. 

I hope that there is a light bus or taxi service that provides a low cost service for a local town and allows people to move around easily. The waiting time should be less than 5 minutes. This will be more convenient than driving. It will reduce congestion and lack of parking space.
