You know the routine — wait at one red light, only to meet another at the next intersection, and another. In cities, we are spending 40% of our time idling, according to Stephen Smith, a professor at Carnegie Mellon University. The time adds up: the average American spends 42 hours a year in traffic — almost two complete days, says Inrix, an analytics firm. New Yorkers spend more than twice as long — 89 hours.

Why it matters: Smith says our traffic systems have not changed in a half-century. Down the road, we will have self-driving cars. Before then, though, we can enjoy less road anxiety.

What is happening: In Pittsburgh and Atlanta, drivers are now more systematically moving along major streets, the result of the installation of intelligent traffic systems designed by Smith. Using cameras, radar and radios, the systems figure out on the spot which lights should be red, and which green.

Cities and companies are catching on to the chance to use new technologies to get people through lights faster. There are apps that tell you when a light will turn green. But Smith notes that none of them actually changes the lights according to what is going on in real-time. His systems cost about $20,000 per four-way intersection.

In the future, Beverly Hills, CA., Portland, Maine, and Dubai plan on installing Smith's system, he says. For now, writers are citing the traffic system as part of why Pittsburgh seems so cool these days. And last month, Atlanta launched "North Avenue Smart Corridor," including the technology. The 2.3 mile corridor, which has 18 intersections, includes Georgia Tech and Coca Cola's world headquarters. Speaking of the corridor in DC on Oct. 5, Mayor Kasim Reed said, "It's going to be a living lab for the city of Atlanta."

Rep. Kathleen Rice (D-N.Y.) on Monday evening called for New York Gov. Andrew Cuomo (D) to resign, after a third woman accused him of inappropriate behavior.

Driving the news: Anna Ruch, a former member of the Obama administration and the 2020 Biden campaign, told the New York Times Monday that Cuomo asked to kiss her at a New York City wedding reception in September 2019.

Scoop: Inside the GOP's plan to retake the House

House Republicans will reclaim their majority in 2022 by offering candidates who are women, minorities or veterans, a memo obtained by Axios says.

Why it matters: The document, drafted by a super PAC blessed by House Minority Leader Kevin McCarthy, names top Democrats to target — Jared Golden of Maine, Matt Cartwright of Pennsylvania and Ron Kind of Wisconsin — and the type of Republican candidates to beat them.

Scoop: Trump talked out of early Ohio endorsement

Donald Trump had to be talked out of making an early endorsement in Ohio's 2022 U.S. Senate race, a sign of his eagerness to reengage politically, people familiar with the conversations tell Axios.

What we're hearing: The former president discussed endorsing former state GOP chair Jane Timken last week during a meeting at Mar-a-Lago with RNC Chairwoman Ronna McDaniel, but top advisers — including Donald Trump Jr. — urged him to wait.
