2006年进行的一项测试评估了保持安全速度和安全距离的驾驶员辅助系统（简称SASPENCE）对驾驶员行为、反应和接受度的影响。通过广告招募的20名测试驾驶员在真实交通条件下沿着一条50公里长的测试路线（包括意大利都灵郊外的城乡道路和高速公路路段）驾驶两次（一次系统关闭，一次系统开启）。记录驾驶数据，并通过车内观察方法观察测试驾驶员，在这种情况下，由两名观察员与驾驶员一起坐在车内。通过问卷调查收集驾驶员的意见。研究结果表明，该系统在减少警报情况、缩短警报长度、缩短反应时间、增加车距以及与十字路口的弱势道路使用者更好地互动等方面发挥了积极作用。不利的一面是，驾驶员表现略有恶化，穿越中心线的次数增加，对其他驾驶员的便利行为更差，并且在红绿灯处制动更困难。未发现对驾驶员的速度行为、车道选择、车道保持、变道、超车、红灯行驶、转向指示灯的使用和工作量产生重大影响。 (C) 2010 Elsevier Ltd. 保留所有权利。
The effects of a driver assistance system for keeping safe speed and safe distance (referred to as SASPENCE) on driver behaviour, reactions and acceptance were evaluated in a test carried out in 2006. Twenty test drivers, recruited by ads, drove two times (once with the system off and once with the system on) in real traffic conditions along a 50 km long test route containing urban and rural roads and motorway sections outside Turin, Italy. Driving data was logged and the test drivers were observed by means of an in-car observation method, in this case by two observers riding along in the car with the driver. Driver opinions were collected through questionnaires. The findings show positive effects of the system in terms of fewer alarm situations, shorter alarm lengths, shorter reaction times, increased headway and better interactions with vulnerable road users at intersections. On the negative side, driver performance worsened slightly, the number of centre line crossings increased, there was worse facilitating behaviour with regard to other drivers and harder braking at traffic lights. No major effect on speed behaviour of the driver, lane choice, lane keeping, lane change, overtaking, red running, use of turning indicator and workload was found. (C) 2010 Elsevier Ltd.
