Our country has nearly 100 large and medium-sized cities of different sizes and different development.Various cities have formed diversified needs for rail transit construction.New rail transit is a useful supplement to traditional rail transit such as subways.Turnouts are key technologies for rail transit.It is imperative to carry out research on all-round and multi-angle turnouts.In this regard,the institutional composition,switching principles,key structural forms were analyzed and studied,and the research and optimization directions for straddle monorail turnouts,medium and low speed maglev turnouts,etc.were proposed.Combined with the development form of new system rail transit,the key directions for the development of new system rail transit turnouts in the future were proposed.
