There is a new study out that maintains that relatively minor changes in highway design can say lives.
The study, by the Insurance Information Institute, explains that “urban roads ‘weren’t built to accommodate today’s heavy traffic. They’ve evolved as traffic has increased, and they haven’t always evolved in the best way to enhance safety and ensure a smooth flow of traffic.'” A news report about the study says that “the majority of traffic fatalities happen on rural roads, but safety experts say urban arteries remain dangerous. About 8,000 traffic fatalities and more than 1 million injuries occur annually on urban roads.”
The article gives several examples of how spending a relatively small amount of money can improve safety.
