Leon’s London
Why are there different kinds of passengers at different times of the day?
What impact does traffic congestion have on the bus journey?
Why is traffic pollution an important factor in the design of the bus?
What would be the problem in this context with using a bus that simply had a
diesel engine driving the wheels?
