Many traffic accidents are caused by, or at least related to, inadequate mental workload, when it is either too low (vigilance) or too high (stress). Creating variations in mental workload and accident-prone driving for research purposes is difficult in the real world. In driving simulators the measurement of driver mental workload is relatively easily conducted by means of physiological measures, although good research skills are required and it is time-consuming. The fact that modern driving simulator environments are laboratory-equivalent nowadays allows full control with respect to environmental conditions, scenarios and stimuli, and enables physiological measurement of parameters of mental workload such as heart rate and brain activity. Several examples are presented to illustrate the potential of modern high-standard driving simulator environments regarding the monitoring of drivers' mental workload during task performance.
许多交通事故是由、或至少与不足的心理工作量有关，无论是过低（警戒）还是过高（压力）。在现实世界中，为了研究目的，创造心理工作量的变化和易发生事故的驾驶行为是困难的。在驾驶模拟器中，通过生理测量来相对容易地测量驾驶员的心理工作量，尽管需要良好的研究技能并且很耗时。现代驾驶模拟器环境如今已经相当于实验室环境，这使得可以完全控制环境条件、场景和刺激，并且能够对心理工作量的参数（如心率和脑活动）进行生理测量。本文提供了几个示例来说明现代高标准驾驶模拟器环境在监测驾驶员在任务执行期间的心理工作量方面的潜力。
