Do you think this “Cyclist Wing” work in Singapore?

Riding in Seoul with a safety cyclist wing
Riding in Seoul with a safety cyclist wing

A conceptual work I did for the Seoul Cycle Design competition.
Cyclist safety is one of the main concern that stop potential cyclist to choose bicycle as a mode of transportation.
Many drivers, even some cyclist, believe cyclist enjoy the road at the expenses of road tax paying car-owners.
The “Cyclist Wing” enhance cyclist visibility and safety on the road. From the driver’s perspective, the “Wing” makes cyclist becomes 300% more visible, and therefore easier to avoid.
“Safety by number” is an important factor supported by a huge body of research finding. More cyclist = more safety for cyclist .
The “Wing” makes the visual population of cyclist in any city increased to 300% with the same number of cyclists. Driver need to drive more carefully due to the apparent increase number of cyclists on the road.

With the air-cleaning function of the “Wing”, cyclists make a tangible contribution to the environment, at the same time return the right-of-way to cyclist.
it is also a subtle reminder of the harmful pollution from cars. The “Wing” earn the right-of-way for cyclist from a social perspective.

The “Wing” will help to tilt the favor towards cyclists and turn more potential cyclist into real cyclist.

Do you think the air-cleaning-cyclist-wing concept can work in your city?

Cycling in heavy traffic is unhealthy?

Sometime we hear that cycling in heavy traffic is unhealthy, more so than driving a car. To test this hypothesis, teams of two cyclists and two car drivers in two cars were equipped with personal air samplers while driving for 4 h on 2 different days in the morning traffic of Copenhagen. The air sample charcoal tubes were analysed for their benzene, toluene, ethylbenzene and xylene (BTEX) content and the air filters for particles (total dust). The concentrations of particles and BTEX in the cabin of the cars were 2–4 times greater than in the cyclists’ breathing zone, the greatest difference being for BTEX. Therefore, even after taking the increased respiration rate of cyclists into consideration, car drivers seem to be more exposed to airborne pollution than cyclists.
