Data-Smart City Solutions: America’s roads need help. In a 2013 report on the state of U.S. infrastructure, the American Society of Civil Engineers gave road infrastructure a ‘D’ grade. According to the report, 32 percent of America’s major roadways are deficient, with particular concentrations of disrepair in urban areas: while only 15 percent of vehicle miles traveled on rural interstate highways are over pavement considered deficient, the number jumps to 47 percent in urban areas. These poorly-maintained roads cause vehicle damage and waste gasoline, costing the average American driver $324 each year.
Cities are looking for ways to direct their street improvement resources more effectively, given the limited personnel to monitor streets and anemic funding for repairs. For instance, City of Boston employees currently conduct a visual survey of each street in the city every three years, a method that is expensive, time-consuming, and leaves streets unmonitored for years at a time. To improve upon this system, some cities are turning to digital monitoring to replace traditional techniques, enabling more frequent and accurate assessment of infrastructure quality. These digital methods primarily fall into one of two categories: vehicle-based monitoring systems, which collect data via an array of sensors attached to a vehicle (usually owned or contracted by the city), and smartphone-based monitoring systems, which leverage built-in smartphone functionality to gather road data.
