Public urban passenger transit in the City of Zagreb consists of trams, buses and rail traffic. Constant growth of the motorization level in the City of Zagreb, and the existing condition of public urban transit, which fails more and more in satisfying the traffic demand, impose the need to introduce a new urban transport subsystem. In order to meet the current and future needs, and to improve the level of the quality of service, the introduction of a LRT (light rail transit) system is proposed, which has also been planned by the urban planning-traffic documentation of the City of Zagreb. One of the problems in the planning of the LRT system is the selection of the track gauge regarding the possibility of connection to the existing tram network, which uses 1000 mm (the railway network uses 1435 mm). This paper applies the AHP method (Analytic Hierarchy Process) for the selection of the optimal track gauge, as one of the multi-criteria decision making methods. The hierarchic structure of all relevant criteria and their sub-criteria will be defined. Keywords: LRT - light rail transit, AHP - analytic hierarchy process, public urban transport. 1 Introduction As the capital of the Republic of Croatia, the City of Zagreb with 779,145 citizens is faced by the problem of sudden growth in individual traffic, especially for home–work trips, which results not only in the formation of forced traffic flows, but also in the reduction of the quality of living in the city itself. Due to the unsatisfactory level of service of the existing public urban transit, as well as because of the restrictions in raising this level, the City of Zagreb has decided on
