It is likely that accident happens when Yi-zhong shopping distinct is crowded with people and vehicles. Consequently, former chairman of Yi-zhong shopping distinct association, once made effort to improve this situation and actively strive for setting a pedestrian zone.

After a hard fight by Chen, in 2010, Taichung city government adopted Chen’s idea; however, it turned out a failure.

The original idea of the project was well intentioned, mainly expecting colorful tiles to beautify the ground. Unfortunately, after completiont, tiles got slippery whenever it rained, thus motorcyclist usually slipping over it.

City government took remedial action to prevent slippery for four times gradually by means of surfacing the street with stone-like coatings and spreading the quartz sand to improve adhesive force of coatings and to strengthen the coefficient of friction.

Although the slippery situation has been solved, the pavement can’t withstand the heavy pressure of the passing cars. Thus, it was eventually covered with scars and pits.

In view of it, we understand that not only well-organized plans and sufficient backup methods are needed, but we also have to make sure the idea we plan to do is feasible. Therefore, on the basis of former examples and analysis, we suggest to adopt multicolor asphalt to replace the colorful tiles, making it possible to improve the environment quality at the same time.
