LRT Rides

With the introduction of four-car trains, the lrt rides is very comfortable because the passengers density in the train is very low. As compared to before when there are only two-car trains available, lrt rides especially during peak hour is very demanding and uncomfortable due to very high passengers density. In term of return of Investment (ROI), how could anyone justify the improvement in term of passengers comfort with respect to the cost of purchasing the four-car trains? Thus, the intangible benefits as a result of certain type of investment needs to be taken into consideration. Usually, those public projects that results in decreasing user costs can be considered as very beneficial and need to be quantified properly.
