Shared lane markings. Bike lanes painted a bright color. Bike boxes at intersections. Cycle tracks that provide physical barriers between bikes and cars. Communities have built these and other flavors of infrastructure to try to make it safer for people to ride their bikes along roadways or through neighborhoods. But which ones work best?
The next time you’re sitting at a red light and cursing traffic, remember: it could be significantly worse. In fact, it would be worse for a number of major commuting corridors in the Atlanta area — if not for the efforts of people like two Georgia Tech civil engineering alumni who are involved in a pacesetting state program to make traffic flow more smoothly.
Appearing on the GPB public radio program On Second Thought March 16, transportation research Michael Hunter said the jury remains out on whether autonomous vehicles will make our roads safer. Hunter said such questions are the focus of inquiry as cities and states move closer to allowing the driverless cars on their roadways.
No single solution will be able to untangle one of metro Atlanta’s worst areas for traffic, the Perimeter Center at the top end of Interstate 285. Rather, Associate Professor Michael Hunter suggested to the Sandy Springs Reporter, the area needs a combination of approaches, from public transit and corporate shuttles to multi-use trails and telecommuting.
A smartphone app and related study for Atlanta bicyclists has won the first-ever Excellence in Innovation / Research of the Year Award from the Young Professionals in Transportation organization. The Cycle Atlanta app, developed by CEE’s Kari Watkins and Christopher Le Dantec from the School of Literature, Media, and Communication, tracks the routes cyclists travel through the city and allows them to note amenities or problems along the way. That helps other riders, and it helps the city develop cycling infrastructure in the right places.
Voters in the City of Atlanta will decide in a few weeks on a $250 million bond referendum that includes, among other things, millions to sync the traffic signals across the city. Creative Loafing’s Max Blau asked the School of Civil and Environmental Engineering’s Michael Hunter how syncing works.
