Do Bike Lanes Save the Planet?

Cannon St. Bike Lanes Analysis

Purpose:

To examine whether the theory that reducing the efficiency of traffic flow can be reasonably expected to have an impact upon the Earth's changing climate.

Basis:

These are estimates derived from quick Google searches. They are designed to generate some ball-park numbers to determine whether the vehicle exclusion lanes along Cannon St. E., from Sherman Ave to Hess St., are actually saving the planet, (Assuming the AGW hypothesis is not a hoax.)

Traffic volume on Cannon St. East: minimum 9,000 vehicles per day
Excessive vehicular idling as a result of bike lanes: 1 minute per vehicle per trip (derived from experience)
Amount of CO2 emitted during politically induced idling: 69 g/min
Length of bike lanes (Sherman to Hess): 3 Km
Number of crack-head bicycle trips per day: 550
Total number of bicycle trips per day: 600
Average CO2 emitted by cyclist: 21 g/Km
Average CO2 emitted by moving vehicle: 185 g/Km

Assumption

For the purposes of this discussion, it will be assumed that the vehicles and the crack-heads cover the entire 3 Km distance of the route.

Analysis

The 600 daily crack-head bicycle trips along Cannon St. generate about 600 trips X 3 Km/trip X 21 g CO2/Km = 37,800 g CO2.

If these trips had been by automobile, the total amount of CO2 emitted would be about 600 X 3 Km/trip X 185g CO2/Km = 333,000 g CO2.

CO2 reduction as a result of cycling instead of driving: 333,000 g CO2 - 37,000 g CO2 = 295,000 g CO2.

The bicycle lanes thus reduce carbon emissions along Cannon St. E. by an impressive 295 kilograms per day.

On the other hand, the unnecessary idling caused by the vehicle exclusion lanes result in a total of 9,000 trips X 1 minute idling per trip X 69 g/min idling = 621,000 g of CO2. (621 Kg.)

Therefore, the politically sexy, but environmentally indefensible, congestion caused by bike lanes along Cannon St. E. results in an increase of 621 Kg - 295 Kg = 326 Kg. of CO2.

Conclusion:

The bicycle lanes along Cannon St. from Sherman Ave. to Hess St. result in increased CO2 emissions of about 326 Kg per day. Multiplied by 365 days, that yields an additional 118,990 Kg of totally unnecessary carbon "pollution" per year.

It appears that the claim by politicians, that they have the power to influence the Earth's climate, by screwing up traffic flow, is no more credible than their demonstrated expertise when it comes to road maintenance, or taxicab regulation, even if we assume that the AGM hoax is actually correct.

Were you expecting something different?

My Encounter with an Uber Cab Driver I had an encounter with an Uber cabbie this morning. When I pulled into the parking lot at the front of my townhouse complex, I noticed this guy sitting in a small, Uber-like car, staring at this dash-mounted smart-phone, and looking confused. He was sitting in front of unit #1. I got out of my car and started walking toward my own unit which is also numbered. It's not a gigantic complex, so in my simple, low-tech, cab driver's mind, I figure that if you are looking for a unit number at an address, the first thing you should do is look at the number on the unit. If that number is "1" the next thing you do is look at the number on the next unit. Often, though not always, that number is either a "2" or a "3" depending upon the numbering format. In my complex, the next number is "2" and so on. For a taxi driver that information can be critical. So this guy looks up at me as I am walking by, and ask…
Fluid Law and how Uber Successfully Exploited It The guy almost gets the story. One thing he misses, though, is how Uber, with its "Madison Avenue" strategy is able to exploit the natural, systemically inevitable, corruptibility of most politicians. This whole Uber phenomenon would not have been successful at all, given that taxi regulations already exist, unless they could get the politicians on board, and convince them, or persuade them to pretend they actually believe, that Uber was not in the taxi business. Hence, Uber taxis are exempt from existing taxi regulations. Most people would interpret this state of affairs as a tilting of the playing field, which it is. The sleazebags at Hamilton's City Hall came up with the term, "New Licensing Category" in order to facilitate Uber's circumvention of the existing taxi bylaw. "New Licensing Category" is nothing but a code word for tilting the playing field in favour of a politically sexy fad. I…
Uber in Hamilton Update: Maria Pearson, Don't Delete This One.Molly A cabbie friend of mine told me that she had recently received a follow-up call from her council rep, Maria Pearson - Ward 10, over a recent licensing issue. After some small talk, the councilor asked my friend, I'll call her Molly, how things were going in the Hamilton taxi business now that Uber had been formally exempted from Hamilton's "old category" of taxi licensing bylaws. Molly told her that things were really bad. Then Molly suggested that if Maria wanted more information on the Uber impact, that she should talk to "Hans." Maria replied, "Hans Wienhold?" Molly: "Yes." Maria: "Oh. I just delete his emails." When I heard this I laughed. First, Maria feigns interest in the plight of Hamilton's cabbies (probably just fishing for a vote, IMHO,) and then, when offered a source of information on the Uber impact, Maria unconsciously intimates th…
