This cartographer highlights the enormous wealth disparities in Los Angeles. Putin is spending billions of dollars to revitalize Russian cities. Congestion is usually seen as a bad thing, but it can also be an indicator of economic vitality.

Topography of wealth: Nick Underwood, a cartography and GIS student at University of Wisconsin - Madison, assembled a sobering visualization of income inequality in Los Angeles. He uses topography to display a city of 58 billionaires and some 58,000 people experiencing homelessness, with taller tracts representing higher incomes. Using 2017 census data, he draws attention to the county's west side, where communities like Beverly Hills have become high plateaus of wealth surrounding areas of extreme poverty. (Nick Underwood)

Putin's redevelopment plan: The Kremlin has dedicated billions of dollars to modernize Russian cities. $31.7 billion has gone to Moscow alone, and another $1.5 billion has been spent annually to transform rail, streets, and squares in smaller cities which have been depopulating as residents move to Moscow. The hope is to make them more attractive again and provide an alternative for people priced out of larger cities. In a survey of 14 global cities, Muscovites reported higher-than-average satisfaction with their urban improvements. (Leonid Ragozin | Bloomberg)

Good and bad congestion: Congestion is almost universally seen as bad, but that view might be overly simplistic. Robert Steuteville posits that some congestion can be a symbol of economic health, citing a study suggesting a positive association between congestion and productivity. In short, bad congestion is where people want to go through, but good congestion is where people want to be. Steuteville provides methods to increase the good congestion while reducing the bad, like limiting off-street parking and improving transit. (Robert Steuteville | Public Square)

Fixing road forks: Forks in street grids create dangerous intersections whose intersections must operate with too many phases. Rerouting and condensing traffic flow yields less points of conflict and opens up space for public parks and plazas. Jeff Speck provides graphics and a video of the redesign of Boston's Kenmore Square. This “very forky” five-way intersection that may soon transition from a complex intersection unsafe for pedestrians and bicyclists to a public space accessible to all users.

Rising western skyline: The Western US has often been emblematic of post-war suburban sprawl, but as its populations skyrocket, so do its downtowns. As larger cities like Denver and Seattle prepare for their first towers at 1,000 feet tall, more humble towers in smaller cities as Long Beach or Sacramento similarly create dramatic new figures in their skylines. Architects and planners believe that soon these skylines will rival the older, taller cities of the East. Skeptics fear they merely signify gentrification.
