The design and mi plementati n f the bus-m unted sy stem in intelligent transp rtati n are described and then s m e key p in ts in hardw are and s ftw are design are discussed in detail. The new m eth d f r passenger fl w c llecti n based n the designed new m dule is presented. It is sh w n that the new m eth d can c llect accurate data at l w c st and h igh perf rm ance c mpared w ith th- ers. Th is sy stem mi plem ents the functi ns f l calizati n, aut m atic bus st p rep rt, data tran sm is- si n and w ireless data update. Based n queue the ry, a mathematicalm del f accessing capab ility is c nstructed and smi ulated. The resu lt sh w s that the bus-m unted sy stem can access stati n sy stem successfully.
