Compared to the other vehicles, bicycle has a smaller volume and with lower lighting position. When the bikers are riding on a bridge or through the tunnel, they are easy to get a bike accident because the other road-users ignore of them riding in the front of the road under a rainy day or a foggy day. The General Administration of Highways has been setting bicycle intelligent warning system in the tunnel and curve road where being with poor visible section since 2019. Up to now, there are 8 warning systems are running, including Provincial Highway No. 2C Pingshuang Tunnel, 9D, 9E, and 30 Yuchang Tunnel. These systems not only remind road users that there are bicycle- rides in the front of the road but also can count the number of bicycles. By collecting the bicycle flow we can realize the characteristic of bicycle riding on that road section. This research will analyze the frequency of the bike accident after setting this warning system on the road section and will explore the influence of the bike flow during a workday or a holiday and or from the weather temperature, and also will propose the prospects of the bicycle intelligent warning system. |
