Measuring the state of a road - Project

Innovations, ideas or patents for sustainable development. Decrease in energy consumption, reduction of pollution, improvement of yields or processes ... Myths or reality about inventions of the past or the future: the inventions of Tesla, Newman, Perendev, Galey, Bearden, cold fusion ...

Before you begin to find solutions, you have to ask the right questions.
Who will use the system?
What do you want to do with data?
What price, quantity of devices to have a usable result?

It would seem, according to an engineer who works on similar apps, that an infrared camera with an image processing algorithm could do the job perfectly.
The project is progressing, it is becoming clearer. To be continued...

Frankly, don't you think there are other fights to be fought "a little" more urgent than the comfort of your buttocks in the saddle of a bicycle?

@GuyGadebois : there are always more important things to do, starting by defining what is important for each of you.
Brigitte Bardot has long been criticized for having launched her crusade against the massacre of baby seals on the ice floes when there was so much human misery around the world ... baby seals are less destitute today. The principle is that everyone invests in the field that seems important to them and in which they think they will be useful!
Bikes and Baby Seals, same fight!


This project still has several goals:
- promote the Government Plan-Vélo launched a year ago and which is still stalled,
- help the Prime Minister in his wish to triple the share of bikes in our daily trips to reach 9% in 2024,
- change the% that our Minister of Ecology, Mr de Rugis, reminded us: cycling is 10% of journeys in Germany and 28% in the Netherlands, against only 3% in France,
- provide precise information on a degraded road and cycle surface: elected officials want concrete information before making decisions. (When the association of bicycle users report that a section is difficult or even dangerous for cyclists in a municipality, elected officials respond that they need more information than a simple report),
- promote the development of cycling in the city and increase cycling facilities (secure and comfortable),
- reduce urban pollution and reduce road accidents by replacing cars with bicycles,
- make students work on a concrete subject which will allow them to put their learned knowledge into practice,
- increase comfort for delicate grelinette buttocks ...
It's already good!

Who will use the system? associations of cyclists, or even urban planning services which manage cycle paths
What do you want to do with data? elected officials, the population (when I go for a bike ride with my children, I sometimes regret having chosen a difficult route because of a high road surface
What price, quantity of devices to have a usable result? : The price is to be defined. For what result: the idea is that the members of cycladic associations take turns to establish the cartography of the routes of their commune, as for example that is currently done for counting cyclists

It must be recognized that the wheel is totally dependent on its physical support because it is the whole that is functional. Many civilizations did not "invent" the wheel, not by incapacity, but because of the impossibility of establishing the adequate infrastructure.
The practice of cycling is more sensitive to a solid coating than other modes of locomotion due to the weakness (or absence) of the suspension, as well as the low inertia of the bike + cyclist assembly which makes it noticeable the slightest defect in the roadway. We should also mention, in addition to the deterioration of the coating, certain cycle paths treated "under the leg", on slopes and made up of rolling gravel ... : roll:

Not at this point but often the cycle path in a suburban environment is less bad.
To come to my work, the municipality decided to reduce the roadway and made a track at the level of the sidewalk. Now there are waves and in addition the coating is full of bumps. To make sure it breaks, a strip of small gravel stuck together separates the pedestrian part of the track. If the wheel is tangent to this strip it deflects the handlebars.
Those who lay this should not cycle in town.

As for school canteens where we will serve children at least one organic meal per week, our elected officials should cycle to work at least once a week! ...
