We illustrate that the electrification of our transport system might impose unnecessary extra congestion and delay for daily commuting passengers. By modelling travel behaviors of these passengers, it is found that more of them tend to depart at a narrower peak-hour time window. The occurrence of this shift is mainly caused by (1) the energy consumption of electric vehicles (EVs) is much lower than that of traditional vehicles and (2) the energy consumption of EVs is less sensitive to congestion than that of traditional vehicles. We further examine the role of congestion toll in minimizing the extra congestion and delay.

电动汽车的一个未被注意的副作用

我们举例说明，我们交通系统的电气化可能会给日常通勤乘客带来不必要的额外拥堵和延误。通过对这些乘客的出行行为进行建模，发现更多的乘客倾向于在较窄的高峰时段离开。这种转变的发生主要是由于（1）电动汽车（EV）的能源消耗远低于传统汽车；（2）电动汽车的能源消耗对拥堵的敏感度低于传统汽车。我们进一步研究了拥塞收费在最小化额外拥塞和延迟方面的作用。
