Abstract：Abstract：Research purposes： The traffic flow^ of traffic hub has the fixed characteristics， and lane edge and its connection road are used to collect and distribute passenger flows fast，so the design is different from the urban road and highway design. There isa lack of systematic study of the relevant design standard，which has become the weak link in
the design work. In this paper，the design standard are discussed.
Research conclusions ：( 1) The deign speed of connection road of lane edge can be selected according to the actual situation from40km/h，30km/h or 20km/h. (2) The plane alignment of connection road of lane edge can sleet linear standard according to the design speed，and the graphic design of lane edge is affect by hub station form factor. (3 ) The
longitudinal slope standard of connection road of lane edge can choose the reference standard of urban roads，but frozen
snow area should not be greater than 4;，when the minimum vertical slope is less than 0.3;，drainage design should
be strengthened，lane edge profile is controlled by the joining part hub station elevation. (4) Lane edge cross section is
composed of the edge of the road belt，the through lane，buffer lane，drop - off lane and drop - off platform. Drop - off
lane width is suggested to use 4.0 m，drop - off platform width to use 2. 0 m，and the other lane width can be selected by referring to urban road design code. (5) The research results have strong practical value in the design work of the highway of large comprehensive traffic hub.
