摘要: 为了探讨拥挤收费对城市居民出行行为的影响,提出了考虑收费的非集计交通方式分担模型,推导了乘客的理解期望收费效用。根据实例测试证明了模型的可用性,进行了收费费率对交通方式分担结构影响的敏感度分析。结果表明,城市交通拥挤收费将影响出行者的交通方式选择行为和满意度,造成城市交通方式分担结构的变化;理解期望效用随收费费率的增加而增大,达到某一值后保持不变,而出行者对拥挤收费的满意度均为负值,并随着出行者对收费认知的不同而以不同的速度减小。

Abstract: For discussing the impact of congestion pricing on travel behaviors of residents, a disaggregated modal-split model considering pricing is formulated, and based on it, the traveler’s perceived expectation utility function is built. Through a case study, the serviceability of this model is tested, and the sustainability of the impact of congestion pricing on the modal-split proportion is analyzed. In addition, we find out that the congestion pricing may have influence on both the traveler’s choice behavior and the satisfactory degree and make the modal-split proportion change. Moreover, the perceived expectation utility increases as the pricing rate increases and stands on a fixed value after reaching the maximum value; whereas traveler’s satisfactory degree value is negative, it decreases in different velocities for various perception degrees.
