Abstract

This paper quantifies the perceived cost of utilitarian cycling energy expenditure as the marginal rate of substitution between energy expenditure and travel time (MRSet). This trade-off manifests in, and can be inferred from cyclist cruising speeds. Median MRSet values for observed cruising events in a naturalistic cycling dataset range from 0.05 to 0.95 min/km per kcal/min. The revealed cost of energy expenditure (relative to travel time) increases significantly with road grade, traffic controls, and certain facility types, and is also significantly higher for women, less-dedicated cyclists, and people riding on weekends and for non-commute purposes.

实用性骑行能量消耗与旅行时间的显性偏好
本文将功利性骑行能量消耗的感知成本量化为能量消耗与旅行时间之间的边际替代率(MRSet)。这种权衡体现在骑车人的巡航速度上,并可以从巡航速度中推断出来。在自然骑行数据集中观察到的巡航事件的 MRSet 中值范围为每千卡/分钟 0.05 至 0.95 分钟/公里。能量消耗的显性成本(相对于旅行时间)随着道路等级、交通管制和某些设施类型的增加而显著增加,女性、不太专注于骑自行车的人、周末骑车的人和非通勤目的的人的能量消耗成本也显著增加。
