Pew: Speeders Take Over Empty Roads — With Fatal Consequences

Pew: Speeders Take Over Empty Roads — With Fatal Consequences. “Daily vehicle traffic dropped by two-thirds nationally from March 1 through April 10, according to StreetLight Data, a San Francisco-based traffic analytics company. And while many states, such as California and Ohio, have seen a reduction in overall crashes during the pandemic compared with last year, some are reporting a jump in traffic fatalities that they say is linked to speeding or reckless driving.”

Crashes Down: Real-Time Data Shows Stay-at-Home Orders May Be Saving Lives in More Ways Than One (California Streets Blog)

California Streets Blog: Crashes Down: Real-Time Data Shows Stay-at-Home Orders May Be Saving Lives in More Ways Than One. “Researchers at UC Davis’ Road Ecology Center are using real-time collision report data from the California Highway Patrol to measure and compare crash rates during the stay-at-home orders. The preliminary report [PDF] finds that collisions have reduced by half since the order went into effect on March 20, from about 1,000 collisions per day a year ago to about 500 per day, and from about 400 injury or fatal crashes per day to about 200. The data is from state highways, which in some cases are freeways and rural roads but can also be main streets.”

Hindustan: This user ‘hacked’ Google Maps traffic flow in an entire area with 99 smartphones

Hindustan Times: This user ‘hacked’ Google Maps traffic flow in an entire area with 99 smartphones. “We often hear apps and services being hacked or breached resulting in user data sharing without consent. But the latest ‘hack’ found on Google Maps is quite an unusual one. It doesn’t leak your personal information to others or breach your smartphone but simply messes with the traffic information that Maps shows you. The ‘hack’ also shows how easy it is to change the traffic flow and indirectly make millions in the area take a different route.”

Bing Blogs: Routing made easier with traffic camera images and more

Bing Blogs: Routing made easier with traffic camera images and more. “After launching traffic camera imagery on Bing Maps in April, we have seen a lot of interest in this new feature. You can view traffic conditions directly on a map and see the road ahead for your planned routes. This extra visibility helps you make informed decisions about the best route to your destination. Based on the popularity of this feature, the Bing Maps Routing and Traffic team has made some further improvements to this routing experience.”

The College of New Jersey: Civil engineering students and their professor apply big data to understand New Jersey’s bumper-to-bumper lifestyle.

The College of New Jersey: Civil engineering students and their professor apply big data to understand New Jersey’s bumper-to-bumper lifestyle.. “On a 100-degree day in late July, civil engineering professor Tom Brennan and three students in his research lab made it snow. No, indoor precipitation was not in the forecast: the snow storm was a computer simulation of an actual one that blew in pretty much out of nowhere on the afternoon of November 15, 2018, creating traffic nightmares throughout New Jersey.”

Techdirt: Why Navigation Apps, Working Properly, Can Make Traffic Flows Worse — And What To Do About It

Techdirt: Why Navigation Apps, Working Properly, Can Make Traffic Flows Worse — And What To Do About It. “Techdirt has just written about how advanced digital technology can be used for less-than-benign purposes, simply because it is a tool that can be applied in both good and bad ways. A fascinating analysis by Jane Macfarlane in IEEE Spectrum explores something similar: how new technology being used as designed, and with only the best intentions, can nonetheless give rise to potentially serious problems.”

Southern Gazette: Council wants Google to fix rat-run street

Southern Gazette: Council wants Google to fix rat-run street. “THE City of Belmont wants Google Maps to change its software to stop a small suburban street from being used as a rat run by drivers accessing Perth Airport and DFO shops. Redcliffe residents say since the permanent closure of Brearley Avenue – the main access to the airport – last year, commuters were being directed by Google Maps down Epsom Avenue on to Stanton Road.” A rat run, in this case, is a small side street or shortcut.

Newswise: Using deep learning to improve traffic signal performance

Newswise: Using deep learning to improve traffic signal performance. “Urban traffic congestion currently costs the U.S. economy $160 billion in lost productivity and causes 3.1 billion gallons of wasted fuel and 56 billion pounds of harmful CO2 emissions, according to the 2015 Urban Mobility Scorecard. Vikash Gayah, associate professor of civil engineering, and Zhenhui “Jessie” Li, associate professor of information sciences and technology [both at Penn State], aim to tackle this issue by first identifying machine learning algorithms that will provide results consistent with traditional (theoretical) solutions for simple scenerios, and then building upon those algorithms by introducing complexities that cannot be readily addressed through traditional means.”
