Please explain the entire solution clearly, step by step in order to understand the entire concept.

1. An LRT line is operated with two-car TUs, each car with capacity of C) = 164 spaces. The headway is h = 3 min and cycle time T = 48 min. The maximum load factor is Amax = 0.88, and the line is operating at capacity. Compute the present ridership on the line. Ridership is growing and offered capacity must be increased by at least 25%. Make the necessary computations to evaluate the following measures: a. Increase train consists from two to three cars b. Improve signal system to allow operation of 2 min headway c. Decrease station dwell and terminal times so that the cycle time is reduced to 42 min. Check whether each one of these alternative measures can meet the required increase in capacity. Discuss the following related aspects of these capacity increasing measures: Investment cost as a function of the number of vehicles Operating cost as affected by the number of drivers Impacts on passenger capacity through headway lengths . 1.
