Mixed traffic situations, where motorists share the road with vulnerable road users, are often very challenging for cyclists. The busy Tamaki Drive in Auckland, New Zealand, is such a challenging environment and has already witnessed several cycle incidents over the past few years, including fatalities and serious injuries. To prevent further incidents from happening, Auckland Transport Authorities decided on a wide range of bicycle safety measures, including the integration of a bicycle warning system, activated by thermal imaging technology from FLIR Systems.

现代自行车的车架由碳纤维增强塑料制成，极其轻便和坚固。但是该种车架的故障情况与原先金属车架完全不同。碳纤维增强塑料制成的车架不会像金属车架那般折弯，而是会断裂，这容易使车手陷入危险，故障可能导致人身伤害甚至死亡。
