激励驱动的向高拼车采用率的过渡
Incentive-driven transition to high ride-sharing adoption
摘要：
拼车-将多次出行合二为一-可能大大有助于实现可持续的城市交通。它在具有许多类似行程请求的高需求位置最有效。然而，在这里我们揭示了人们共享乘车的意愿并没有遵循这一趋势。对个人拼车决策的基本激励进行建模，我们发现两种相反的采用制度，一种是常数，另一种是随着需求的增加而减少。在高需求限制下，这些制度之间的过渡变得不连续，从低到高的拼车采用突然切换。分析纽约市和芝加哥超过3.6亿次乘车请求表明，这两种制度在城市中共存，与我们的模型预测一致。这些结果表明，即使适度增加财政激励，也可能对单个用户群体的拼车采用产生不成比例的巨大影响。
英文摘要：
Ride-sharing - the combination of multiple trips into one - may substantially contribute towards sustainable urban mobility. It is most efficient at high demand locations with many similar trip requests. However, here we reveal that people's willingness to share rides does not follow this trend. Modeling the fundamental incentives underlying individual ride-sharing decisions, we find two opposing adoption regimes, one with constant and another one with decreasing adoption as demand increases. In the high demand limit, the transition between these regimes becomes discontinuous, switching abruptly from low to high ride-sharing adoption. Analyzing over 360 million ride requests in New York City and Chicago illustrates that both regimes coexist across the cities, consistent with our model predictions. These results suggest that even a moderate increase in the financial incentives may have a disproportionately large effect on the ride-sharing adoption of individual user groups.
