Slow traffic accounts for a great part of urban transportation, and is drawn more and more attention. However, the service system for this kind of traffic is rather inadequate, which seriously hampers the construction of smart city and digital urban. In this paper, beginning with the characteristics of slow travel persons, we design a multi-mode traffic information service platform for pedestrians and bicycle system specially. In our platform, non-interactive facilities for slow traffic are designed and deployed oriented pedestrians and cyclists. To provide customized information meeting pedestrians’ various demands and allow users’ feedback, the interactive service platform based intelligent mobile terminals and mobile internet is introduced instead of current electronic inquire equipments settled in public.
