• Slow devolution of most PA roads to localities.• Most of the local roads are not well

Fall, 2010 Next Steps for RODAS

2 major pieces of software needed to make RODAS operational:• Iphone application tailored to CMU server environment• CMU Server/Database and Classification System

2009 Iburgh Project at CMU vs. CityConnect in BostonBoth projects streamed community video to city maintenance departments; RODAS is community based in design

August 23, 2010: 4 undergraduates + Veronica get started with likely cooperation of IT Department of City of Boston/CityConnect

Support of stakeholders (transportation companies, road contractors, and public agencies would make

sense, but has not happened)

Basic idea of trusted 3rd party authentication with location and time stamp of state of affairs (video image) has widespread application
