Because of the increase in congestion in ground access at many airports, rail transit alternatives are getting increased attention. During the conceptual planning phase, it is useful to know the relative attractiveness of such alternatives over other modes. In this research, three concepts are examined:(a) an exclusive rail link from the city center,(b) an extension of an existing rail line to the airport, and (c) an automated people mover or shuttle bus connection linking the terminal area to a station on a nearby rail line. The concepts were evaluated using multicriteria analysis. Quantifiable criteria such as travel time and cost and nonquantifiable criteria such as accessibility, reliability, baggage convenience, and parking convenience were considered in the evaluation. Computer models were developed to determine quantifiable criteria values, and fuzzy ratings were used for nonquantifiable criteria. Passenger demands at which airport rail alternatives become attractive were identified for three usage levels of business passengers and vacationers. The effect of baggage-handling facilities at rail stations on service attractiveness is also presented.
