(a) [12 marks] Define "private transport", "paratransit" and "transit" in at most two lines respectively. Discuss the significance of the type of transport in the strategic public transport planning process, support your discussion with relevant examples. (b) [13 marks] The figure below shows the public transport network between a residential center (X) and an employment center (Y).X and Y are connected by a rail line ( A to A ) and 3 BRT lines (B to B). Service characteristics of the rail and BRT lines are provided in the table below. These transits operate with uniform headway. The value of in-vehicle travel time is $1 per min, and the value of waiting and access time are both $2 per min. - Solve for the optimal strategy form X to Y based on generalized travel cost (in \$). - Comment on whether any of the assumptions made in this question would significantly affect your results.
