[5] Vuchic has made a qualified point about the economic value of public transport for cities, assessing the comparative worth of buses, light rail, or rapid transit.
In the October 1972 report prepared for the Urban Mass Transportation Administration defining light rail, he notes that each has a particular urban-geographic setting in which is the better choice.
He contrasts that with rapid transit, which is superior wherever high-capacity, high-speed service is warranted, due to greater population density.
Light rail is the optimal solution for transit services of the intermediate kind, being competitive with the automobile where there are space restrictions, but where demand is moderate and high-cost investments are not feasible.
[6] Of particular interest is his 1973 study comparing heavy rail service in Lindenwold to bus rapid transit lanes on the Shirley Highway; the Lindenwold High Speed Line (heavy rail) operated with higher ridership and passenger revenues compared to the Shirley Busway, despite the Busway's lower initial capital costs.
