The city of #Calgary produced this informative chart about the avg "true cost of transportation" for #walking (minus 25 c/km), #cycling (1 c/km), #transit (67 c/km) and #driving ($1.25 c/km) a few years ago

You can see their assumptions in the chart https://www.calgary.ca/content/dam/www/transportation/tp/documents/transportation-cost-calculator/tcc-cost-details.pdf

Had a blast with a great group of cyclists on a nippy winter night collecting donations for the Caring Cupboard. Thanks to everyone who donated and came out! #LdnOnt #LdnOntBike
Please boost if you’re still masking indoors (in public places)
In 18 months we've biked 3000 km, saving almost 900 lbs of carbon emissions. We've also gotten lots of fresh air and exercise, met lots of other cyclists, and had a heck of a lot of fun! #Bike #LdnOnt #LdnOntBike #environment

Hey #LdnOnt, the people at the Caring Cupboard need some help, so we're doing a glow ride to collect food and donations. The Caring Cupboard is in a geared to income housing unit on Baseline and they do really good work for their community.

Where: 165 Elmwood St E

When: Dec 8 at 4:30-5:30

Decorate your bike and come on out!

The 9,046-lb Hummer EV is so enormous that charging it can cost ~$100.

"It simply takes a lot more energy to accelerate all that heft. It's just not as efficient as other electric vehicles on the market."

This car is such a disaster.

Charging a GMC Hummer EV to 100% Can Cost You Over $100

With a battery over three times larger than most other EVs, the Hummer EV is a costly vehicle to charge.

The Drive

This study from Canada showed that investments in cycling infrastructure that cause even a tiny increase in cycling mode share save lives, reduce carbon emissions, and have a financial benefit worth millions of dollars. Building bike lanes is fiscally responsible (despite what some people think).

An economic analysis of the health-related benefits associated with bicycle infrastructure investment in three Canadian cities

Objectives Decision-makers are increasingly requesting economic analyses on transportation-related interventions, but health is often excluded as a determinant of value. We assess the health-related economic impact of bicycle infrastructure investments in three Canadian cities (Victoria, Kelowna and Halifax), comparing a baseline reference year (2016) with the future infrastructure build-out (2020). Methods The World Health Organization’s Health Economic Assessment Tool (HEAT; version 4.2) was used to quantify the economic value of health benefits associated with increased bicycling, using a 10-year time horizon. Outputs comprise premature deaths prevented, carbon emissions avoided, and a benefit:cost ratio. For 2016–2020, we derived cost estimates for bicycle infrastructure investments (including verification from city partners) and modelled three scenarios for changes in bicycling mode share: ‘no change’, ‘moderate change’ (a 2% increase), and ‘major change’ (a 5% increase). Further sensitivity analyses (32 per city) examined how robust the moderate scenario findings were to variation in parameter inputs. Results Planned bicycle infrastructure investments between 2016 and 2020 ranged from $28–69 million (CAD; in 2016 prices). The moderate scenario benefit:cost ratios were between 1.7:1 (Victoria) and 2.1:1 (Halifax), with the benefit estimate incorporating 9–18 premature deaths prevented and a reduction of 87–142 thousand tonnes of carbon over the 10-year time horizon. The major scenario benefit:cost ratios were between 3.9:1 (Victoria) and 4.9:1 (Halifax), with 19–43 premature deaths prevented and 209–349 thousand tonnes of carbon averted. Sensitivity analyses showed the ratio estimates to be sensitive to the time horizon, investment cost and value of a statistical life inputs. Conclusion Within the assessment framework permitted by HEAT, the dollar value of health-related benefits exceeded the cost of planned infrastructure investments in bicycling in the three study cities. Depending on the decision problem, complementary analyses may be required to address broader questions relevant to decision makers in the public sector.
