EFFECT OF IMPROVEMENTS IN MOTORCYCLE/MOTORCYCLIST CONSPICUITY ON DRIVER BEHAVIOR
研究了30多种提高摩托车可见性的方法，通过白天和夜间道路测试，发现开启车灯、佩戴高可见性背心等措施能有效减少驾驶员接受短时间间隔的行为。
More than 30 conspicuity treatments were developed, and the most promising ones were evaluated in day and night tests involving ordinary car drivers on public roads. The tests established which conspicuity treatments effectively deterred motorists from accepting short time gaps. Findings showed that daytime conspicuity of a motorcycle is significantly improved if (1) its normal low-beam headlamp is turned on or (2) its high-beam headlamp is turned on and is modulating in intensity three times per second or (3) the motorcyclist is wearing a high-visibility (fluorescent) vest and helmet cover. Nighttime conspicuity is significantly improved when the motorcycle uses additional running lights or the cyclist is wearing a retroreflective vest and helmet cover.
