Welcome back to TheCityFix Picks, our series highlighting the newsy and noteworthy of the past week. Each Friday, we’ll run down the headlines falling under TheCityFix’s five themes: mobility, quality of life, environment, public space, and technology and innovation.

Mobility

The Urban Assault Ride, a bike festival sponsored by a beer brewing company, makes its way through 13 U.S. cities this summer.

Cyclists set a new record for Bike to Work Day, accounting for 75 percent of morning roadway traffic on Market Street in downtown San Francisco.

Employees of the Rea Vaya bus rapid transit (BRT) system in Johannesburg, South Africa went on strike Monday.

Quality of Life

Researchers with the University of Alberta found that people living in neighborhoods where traffic makes it unpleasant to walk were more likely to have their body-mass index (BMI) increase in the last six years than those who enjoyed walking in their neighborhoods.

Environment

Pollution levels are on the rise in Delhi, India, making government officials and event organizers nervous as they prepare for the upcoming Commonwealth Games.

Transport is the second biggest contributor to greenhouse gas emissions in India, with 7.5% of emissions coming from aviation, shipping, railways and road transport.

Transportation would receive more than $6 billion of the revenue generated by selling carbon emissions permits to fuel providers under a new U.S. Senate climate bill introduced this week.

Public Space

More than 55% of roads in Pune, India are used for on-street parking, making walking difficult and dangerous, according to studies from the Centre for Science and Environment.

Mumbai is still the safest city for women in India, according to more than half of respondents to a survey about women’s access to public space. However, “their access to public space is still conditional and they don’t feel the same claim to public space as men do,” said Sameera Khan, who collaborated on the three-year research project.

Technology and Innovation

U.S. Secretary of Transportation Ray LaHood says, “Japanese and Chinese high-speed rail technology and expertise may be on its way.”
