Who is likely to get involved in bicycle accidents?
Bicycles are a popular mode of transportation in Japan, especially among young people on school runs and the elderly. For the elderly, bikes are a cheap and flexible mode of transportation. If they have returned their driver’s license, it might even be the only option left to maintain a certain degree of mobility and independence. Accordingly, the likelihood among elderly and underage cyclists to get involved in traffic accidents is relatively higher. The nature of their risks might differ, however. Although pedelecs have become increasingly popular in recent years among both groups, elderly cyclists with limited stability tend to struggle more with e-bikes, which built-in electric motor makes them heavier and faster than the average bicycle. Since people are aware of this issue, there have been e-bike training courses for the elderly organized by vendors, the police, and local governments. One can hardly measure the direct effects of such initiatives. At least, the casualty rate of elderly cyclists decreased steadily over the past decade. It remains to be seen if this trend continues.
