New Speed Limit in Paris: 30 km/hr

- Adam Clare

This week Wired published an article about the 20 deadliest US cities for pedestrians and they write:

There, low-density neighborhoods “rely on wider streets with higher speeds to connect homes, shops, and schools—roads that tend to be more dangerous for people walking,” the report says. More than half of all pedestrian deaths recorded from 2003-2012 occurred on wide arterial roads designed to move cars quickly.

Paris, is known for its boulevards that accommodate fast moving traffic (in theory) and good pedestrian walking. Over the past few years Paris has had some of the worst traffic problems in the world. They have experienced seemingly never-ending smog and congestion. Their most recent way to curb these problems is to reduce the speed limit.

As traffic speeds are significantly brought down across the city, a number of very important things occur as a direct result: substantially fewer accidents, significant reduction in serious injuries and deaths, energy savings, reduce dependence on imported fossil fuels, local air pollution reduction, quality-of-life improvements all those who live and work, and play and study there, improved conditions and local accessibility for local business, significantly reduced carbon stress on climate, and the long list goes on.

It’s worth noting that Toronto’s crack-mayor with crack-supporters stopped a similar speeding policy in Toronto.

Beets for Road Ice Removal

- Adam Clare

The traditional approach to deicing roads is to cover the roads (and thus the ground around the road) in salt – which is absolutely awful for the environment. Because so many people drive cars the demand for road salt is high and has come to negatively impact local economies and environments.

There is a solution to make salting less damaging and it’s already being used in some communities.

Beets are usually just used to create sugar or, like at Schrute Farms, beet soup. In Ontario roadworks departments have been using a byproduct from beet sugar processing to clear ice off of roads. They mix the beet byproduct with salt to create a new brine that works better and harms less.

Niagara Region has used the mixture for about three years, resulting in a 30 per cent reduction in road salt which damages tender fruit trees and vines, said Dave MacLeod, the region’s manager of transportation operations and technology.
The Ontario transportation ministry is working with Oakville and Grey County to test the effectiveness of other beet juice-based products that are added to brine, said a ministry spokesman.
“The ministry’s objective is to provide safe highways for all travellers by using the best available technology. At the same time, we recognize our responsibility to protect the environment, so we use technology to help us determine the best way to clear our highways in the most environmentally friendly, cost-effective way,” he said.

A Greener Asphalt

- Adam Clare

Roads are often overlooked when it comes to the impact of cars on the environment, but we can’t ignore the roads have on the environment when discussing the practicality of cars. Asphalt is used to make roads and the process of creating asphalt is very energy intensive. In Vancouver, they are looking into ways to lower the negative impact of car infrastructure by making greener roads.

First, it allows asphalt to be heated at 20 to 40 degrees less than is necessary when using the traditional “hot mix” method. This reduces the amount of fuel necessary for the process, which in turn reduces the resulting greenhouse-gas production by as much as 50 per cent. Second, although there are other paving materials that have similar characteristics, they’re normally made of petroleum products. GreenMantra’s product comes from recycled plastics.

The wax is slightly more expensive than petroleum-based materials, but GreenMantra and the City of Vancouver are looking to bring down the cost by sourcing cheaper plastic. The price could also drop of its own accord, as GreenMantra begins to produce the stuff in greater quantities.

Bike Lanes Save Lives and Lower Risk from Cars

- Adam Clare


It should come as no surprise that bike lanes are safer than merging bicycle traffic with heavy metal boxes on wheels. A new study from the University of British Columbia confirms this and goes one step further by analysing which type of bike lane is in the safest. Well designed infrastructure isn’t just good for better, healthier, traffic flow it’s also a way to save lives.

We found that route infrastructure does affect the risk of cycling injuries. The most commonly observed route type was major streets with parked cars and no bike infrastructure. It had the highest risk. In comparison, the following route types had lower risks (starting with the safest route type):

  • cycle tracks (bike lanes physically separated from motor vehicle traffic) alongside major streets (about 1/10 the risk)
  • residential street bike routes (about 1/2 the risk)
  • major streets with bike lanes and no parked cars (about 1/2 the risk)
  • off-street bike paths (about 6/10 the risk)

Bike Lanes Makes Road Safer for Everyone

- Adam Clare

The worst mayor in Canada hates people who don’t drive automobiles and thinks cyclists deserve to die. The mayor of Toronto wants to remove bike lanes (while every smart city is installing more) despite the fact that the number of cyclists has increased. So where’s the good news you ask?

It turns out (much to the chagrin of mayor Rob Ford) that bike lanes improve safety for all road users!

The Toronto Cyclists Union has drummed up a City staff report that compares crash data in the three years previous to the bike lanes and the one year with the bike lanes. The report finds that the overall crash rate for Jarvis has actually decreased by 23 percent. That’s for all road users—bicycles, cars, and pedestrians. In fact, the report notes that “most of this reduction can be attributed to the reduction in collisions involving motor vehicle turning movements and collisions involving pedestrians.”

But the bike lanes have also been better for cyclists. While the number of bicycle-car collisions has increased from an average of 7 per year in the three years prior to the bike lane to 15 in the year with the bike lane, the report notes this still represents a drop in the rate of collision when you take into consideration the fact that the number of bicycles increased threefold post-bike lane implementation.
