Abstract
Recently, many local governments suffering from traffic congestion have plans to introduce light weight (mid-size) rail transit systems, since the systems' investment costs are known to be much less than heavy rail transits such as the subway in Seoul. Most of the governments expect private partners to be involved in the systems' constructions and operations mainly because of their financial difficulties. Since the governments do not have experiences of evaluating and selecting privately financed transportation systems, they may need an evaluation guideline. This paper discusses evaluation criteria, methodologies, and procedures which will be helpful to local governments faced with evaluating light weight rail transit systems proposed by private companies.
