Optimizing traffic signals to reduce wait times at intersections

Traffic lights at intersections are managed by simple computers that assign the right of way to the nonconflicting direction. However, studies looking at travel times in urban areas have shown that delays caused by intersections ...

Power supply: Understanding unstable grids

A sustainable energy supply requires the expansion of power grids. However, new transmission lines can also lead to grids becoming more unstable rather than more stable, as would be expected. This phenomenon is referred to ...

Self-driving cars can make traffic slower: Study

A new study finds that "connected" vehicles, which share data with each other wirelessly, significantly improve travel time through intersections—but automated vehicles can actually slow down travel time through intersections ...

Sick of dangerous city traffic? Remove left turns

To reduce travel times, fuel consumption and carbon emissions, in 2004, UPS changed delivery routes to minimize the left-hand turns drivers made. Although this seems like a rather modest change, the results are anything but: ...

Comparing the promise and reality of e-scooters

Is shared micromobility the ideal first/last mile supplement to transit? Can electric scooters make it easier for historically disadvantaged populations to get around? In just three years, brand-new fleets of e-scooters have ...
