自行車智慧型警示系統設置成果及未來展望

The Results and Prospect of Building Bicycle Intelligent Warning System

自行車體積相對於其他車種小，且車輛本身照明低於汽機車，在視線不佳的情況下，如雨天、起霧或是經過橋梁、隧道等，容易造成其他用路者因未注意前方有自行車而發生事故的機率。交通部公路總局於108年開始陸續於隧道及彎道路段等視線不佳路段設置自行車智慧型警示系統，地點包含台2丙平雙隧道、台9丁、台9戊及台30玉長隧道，該系統除了能提醒用路人前方有自行車行駛以外，亦具備有計數功能，透過自行車流量蒐集可以了解該處自行車行駛特性，本文將探討設置警示系統後對於路段自行車事故之變化以及平假日、週間日與氣溫對於自行車流量之影響，也提出該系統未來展望。

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.
