Post-disaster　road　monitoring　system　provides　an　interesting　application　area　for　wireless　sensor　networks.　After　the　earthquake,　roads　are　subject　to　be　blocked　by　landslides.　The　people　require　a　scalable　and　low-cost　technology　for　getting　real-time　dynamic　data　about　road　availability　because　aftershocks　occur　continuously.　Wireless　sensor　networks　are　a　promising　candidate　to　fulfill　these　requirements.　In　this　paper　the　post-disaster　road　monitoring　system　solution　is　put　forward.　Sensors　selection　and　node　configurations,　node　deployment,　multi-sensor　information　integrated　algorithm,　and　image　collection　mode　are　discussed.　The　multi-sensor　information　integrated　algorithm　is　adopted　to　judge　the　event.　And　the　node　deployment　is　calculated　by　sensor　coverage　radius　and　expectations　and　redundancy　of　the　system.　©　2011　IEEE.
