Emerging Mobility | TNCs and Congestion | San Francisco County Transportation Authority
Clear argument for limiting private vehicles inside cities.

"Key findings in the report:

The report found that Transportation Network Companies accounted for approximately 50 percent of the rise in congestion in San Francisco between 2010 and 2016, as indicated by three congestion measures: vehicle hours of delay, vehicle miles travelled, and average speeds.

Employment and population growth were primarily responsible for the remainder of the worsening congestion.

Major findings of the TNCs & Congestion report show that collectively the ride-hail  services accounted for:

51 percent of the increase in daily vehicle hours of delay between 2010 and 2016; 
47 percent of the increase in vehicle miles travelled during that same time period; and
55 percent of the average speed decline on roadways during that same time period.
On an absolute basis, TNCs comprise an estimated 25 percent of total vehicle congestion (as measured by vehicle hours of delay) citywide and 36 percent of delay in the downtown core.
Consistent with prior findings from the Transportation Authority’s 2017 TNCs Today report, TNCs also caused the greatest increases in congestion in the densest parts of the city - up to 73 percent in the downtown financial district - and along many of the city’s busiest corridors.  TNCs had little impact on congestion in the western and southern San Francisco neighborhoods."

Streetscapes Mozart, Marx and a Dictator
Streets and squares are an archive of both language and history. We discovered some fascinating patterns in the distribution of the 450,000 street names in Germany. They tell the story of almost forgotten artists and historical events, they shed light on obsolete economic structures and trade routes, on dialects and on idioms imported from abroad. Additionally, we identified groups of streets with thematically linked terms like the names of poets or types of animals.
