Mathematically optimizing traffic lights in road intersections

Researchers developed a method to compute optimal traffic light settings for urban intersections by applying traffic flow conservation laws on networks. The approach uses partial outer convexification, splitting the problem into two stages: nonlinear dynamic optimization and linear mixed-integer programming.

Molecular traffic jam makes water move faster through nanochannels

Researchers found that water molecules in carbon nanotubes don't flow continuously but instead move intermittently, resulting in surprisingly high flow rates. This phenomenon resolves a long-standing issue in fluid dynamics and has potential industrial applications for desalination and other uses.

Eliminating unexplained traffic jams

A new algorithm proposed by MIT professor Berthold Horn aims to alleviate traffic flow instabilities, which can cause unexplained traffic jams. The algorithm uses sensor information from cars behind and in front of each other to stabilize traffic flow and reduce the risk of jams.

Progressive traffic signal systems save time and fuel

Researchers developed a control concept that reduces travel time by about a minute and waiting time by up to seven seconds, increasing intersections that can be passed without stops from 60% to almost 100%. A driver information system was also created to provide speed recommendations to vehicles, resulting in improved traffic flow.

Predicting collective online behavior

A team of Chinese scientists found that small websites with high user interaction have a significant impact on traffic generation and influence. The study analyzed clickstream networks of the 1,000 most popular websites and revealed that smaller sites have a greater chance of acquiring popularity than larger ones.

Maths tells us when to be more alert on the roads

Researchers used mathematical algorithms to determine that drivers should pay more attention during the shortest lifetime of spatio-temporal correlations of traffic intensity, found to be between 6pm and 8pm. This period experiences high 'stop and go' phenomena, requiring constant driver attention.

9 million bicycles, but what about the cars in Beijing?

Researchers developed an algorithm to optimize traffic flow across roundabouts in Beijing, reducing delays to just 11 seconds. The approach balances entry and exit point delays for smoothest flow, offering a potential solution to the city's chronic congestion issues.
