驾驶困难对ADAS便利条件和接受意愿的影响

研究表明，视力下降引起的驾驶困难（0.150，1.946*）对便利条件有显著正向影响，而听力下降引起的驾驶困难（-0.261，-2.944**）则对便利条件有显著负向影响。这表明，相比于视力下降造成的行车困难，听力下降引起的行车困难更容易导致驾驶人怀疑自己安全操作ADAS的能力。

判断车距困难（0.109，2.02*）对驾驶人接受ADAS行为意向有正向显著影响，表示驾驶人感知到的判断车距困难越严重，越会促成驾驶人购买和使用安装有ADAS的汽车。判断车距困难（0.109，2.02*）、复杂交通行车困难（0.128，1.495*）和记忆力下降引起的行车困难（0.185，1.911*）对驾驶人接受ADAS行为意向有正向显著影响，表示驾驶人在驾驶过程中感知到的判断车距困难、复杂交通下行车困难和记忆力下降引起的行车困难越严重，越会促成驾驶人购买和使用安装有ADAS的汽车；听力下降引起的行车困难（-0.206，-2.275*）对驾驶人接受ADAS行为意向有负向显著影响，意味着听力下降引起的行车困难和反应力下降引起的行车困难会从驾驶人对其本身驾驶能力的怀疑进一步影响到对ADAS简单熟练操作的怀疑，从而对使用ADAS产生消极态度。但往往这样的驾驶人群更需要获得驾驶辅助系统的帮助，因此应该对该类人群进行更细化的培训，为他们熟练使用ADAS进而更安全的驾驶提供信心。

The impact of driving difficulty variables on the convenience conditions of ADAS is shown in Table 6. It can be observed that visual impairment-induced driving difficulty (0.150, 1.946*) has a significant positive effect on convenience conditions, while hearing impairment-induced driving difficulty (-0.261, -2.944**) has a significant negative effect. This suggests that compared to driving difficulties caused by visual impairment, hearing impairment-induced driving difficulties are more likely to make drivers doubt their ability to operate ADAS safely.

Judging distance difficulties (0.109, 2.02*) have a significant positive influence on drivers' intention to accept ADAS, indicating that the more severe drivers perceive difficulties in judging distances, the more likely they are to purchase and use ADAS-equipped vehicles. Judging distance difficulties (0.109, 2.02*), complex traffic driving difficulties (0.128, 1.495*), and memory decline-induced driving difficulties (0.185, 1.911*) have a significant positive impact on drivers' intention to accept ADAS. This suggests that the more severe drivers perceive difficulties in judging distances, driving in complex traffic conditions, and memory decline-induced driving difficulties, the more likely they are to purchase and use ADAS-equipped vehicles. Hearing impairment-induced driving difficulty (-0.206, -2.275*) has a significant negative impact on drivers' intention to accept ADAS, implying that hearing impairment-induced driving difficulties and reaction decline-induced driving difficulties further affect drivers' doubt about their own driving abilities and their ability to operate ADAS proficiently, leading to a negative attitude towards using ADAS. However, these drivers often require the assistance of driving assistance systems. Therefore, more targeted training should be provided to this group to instill confidence in their proficient use of ADAS, promoting safer driving.
