"Uber and Lyft are often touted as a way to reduce traffic, as vehicles can transport multiple passengers travelling along a common route at the same time and it provides a cheaper alternative to owning a car."

The latest study, however, shows that’s not the case. Figures show these dial-a-ride taxi fleets have increased congestion [in San Francisco] by 62 per cent in 2016 compared to 2010. Drivers often cruise around in between trips waiting for nearby passengers to order rides via apps on their phone, a process known as deadheading. It is estimated that 20 per cent of the miles traveled by Uber and Lyft cars are from deadheading.
Who could possibly have predicted this would happen, with the crippling shortage of parking in San Francisco?
Splitting the cost of journeys on these services makes rides cheaper, and it means that people have chosen to take Uber or Lyfts over other modes of transport. The researchers reckon that some 43 per cent to 61 per cent of all ride-sharing trips could have been swapped for w

New research shows pollution from cars is responsible for 4 million new cases of childhood asthma each year


Asthma has many causes, including genetics and allergies. But chief among them is air pollution, especially from traffic. In fact, car exhaust  —  specifically particles of nitrogen dioxide or NO2  —  is responsible for an estimated 4 million new cases of childhood asthma worldwide each year, according to new research published in The Lancet Planetary Health. Looked at another way, car exhaust is responsible for one in eight new childhood asthma cases diagnosed annually, the scientists said. Moreover, cars are a significant source of heat-trapping carbon dioxide, the chief culprit behind climate change.

The Lancet study adds to a growing body of scientific evidence that has emerged in recent years documenting the many risks of air pollution. The American Lung Association has just released its 20th annual “State of the Air” report, which found that 4 in 10 Americans live in areas with unhealthy air quality. And a recent report from the Health Effects Institute said that air pollution kills more people than smoking and projected th... show more

Air Pollution Increases ER Visits — Largest US Study On The Topic Confirms It - Exposure to nitrogen dioxide and fine particulate matter, or PM, can cause grave trouble with one’s health


We may not even see them, but tiny particles, particulates in the PM2.5 size range, are able to travel deeply into the respiratory tract. PM2.5 infiltrates the lungs, all the way to the alveoli, where oxygen is transferred into the bloodstream. Exposure to nitrogen dioxide and fine particulate matter, or PM, can cause grave trouble with one’s health.

Emissions from traffic and poor choices in transit are one of the major causes of our dangerous air. Fresh air, a precious commodity, disappears as many fossil-powered cars, trucks, buses, and off-road vehicles (e.g., construction equipment, snowmobile, locomotive) emit fine particulates from their tailpipes.

A US study published online in the American Thoracic Society’s American Journal of Respiratory and Critical Care Medicine signals that, as levels of ozone and fine particulate pollution (PM2.5) rise,... show more

A US study published online in the American Thoracic Society’s American Journal of Respiratory and Critical Care Medicine signals that, as levels of ozone and fine particulate pollution (PM2.5) rise, more patients end up in the ER. The study looked at the levels of these two pollutants in 869 counties in the week prior to an ER visit for a breathing problem. The study included nearly 40 million ER visits fo... show more

Google Maps is borrowing another of Waze’s best features with traffic slowdown reporting - The Verge

Being able to report incidents on the road, like traffic jams and accidents, has been a staple of Google-owned Waze for years, but it’s just in the past year made its way into the main Google Maps app, one feature at a time.

First subway introduced in in Jakarta

In the final meeting between the council and Jakarta administration, the councilors had decided the minimum MRT fare of Rp 8,500 would cover the first 10 kilometers traveled on the 15.7-km route between Lebak Bulus in South Jakarta and the Hotel Indonesia traffic circle in Central Jakarta. Passengers are to be charged more if they travel farther than 10 km.

“We are taking the middle road: Rp 8,500 for the MRT and Rp 5,000 for the LRT. Everybody agree?” council speaker Prasetio Edi Marsudi, who led the meeting, said while banging the gavel in the chambers of the City Council building in Central Jakarta.

The city administration previously proposed a Rp 10,000 fare for the MRT and a Rp 6,000 one for the LRT, which would have required the city administration to allocate subsidies of Rp 572 billion and Rp 327 billion respectively this year. (ami)

Motorcyclist dead after hitting dead pig


KABC-TV says 57-year-old Bradley St. John was doing about 55 mph Thursday night in Littlerock when he struck the animal, which was directly in his path.

The California Highway Patrol says the minivan had tried swerving to avoid the dead pig but struck both the animal and St. John.

The OpenWrt Project is a Linux operating system targeting embedded devices.Instead of trying to create a single, static firmware,OpenWrt provides a fully writable filesystem with package management.This frees you from the application selection and configuration provided by the vendor and allows you to customize the device through the use of packages to suit any application.For developers,OpenWrt is the framework to build an application without having to build a complete firmware around it;for users this means the ability for full customization,to use the device in ways never envisioned.
