This has directly and strongly affected people’s daily life and work. Meanwhile, the traffic accidents have caught people’s eyes. And what is even worse, along with the accidents come the pollution and noise.

Besides, cycling can replace driving if our house is not so far from where we work. It may take a bit longer but saves energy, avoids traffic jam and improves our health. If possible, we can even walk. In one word, solutions are more than problems.
