互联和自动化车辆（CAVs）有望在安全性、能源效率和时间利用率方面产生显著改善。然而，它们对能源和环境结果的净影响尚不清楚。更高的燃油经济性降低了每英里旅行所需的能源，但也降低了旅行的燃料成本，激励了更多的旅行，并造成了能源“反弹效应”。此外，CAVs预计将大大减少旅行的时间成本，导致旅行和能源使用的进一步增加。在本文中，我们利用现有的旅行行为数据，预测了来自CAVs的诱导旅行和反弹。我们建立了一个在收入和时间约束下车辆行驶里程(VMT)选择的微观经济模型；然后，我们利用2017年美国全国家庭旅行调查(NHTS)的燃料成本数据和基于工资的旅行时间成本预测，用它来估计VMT需求相对于燃料和时间成本的弹性。我们对VMT需求的综合价格弹性的中心估计为-0.4，与以前的估计有很大差异。我们还发现有证据表明，较富裕的家庭有更有弹性的需求，所有收入水平的家庭对时间成本比对燃料成本更敏感。我们使用我们估计的弹性来模拟VMT和能源使用的影响，完全，私人CAV采用在一系列可能的变化燃料和时间成本的旅行。我们预测平均每个家庭的旅行需求将增加2-47%。我们的结果表明，适得其反--即能源使用的净增加--是可能的，尤其是在高收入群体中。随着CAV使用的增加，这不仅对减少能源使用，而且对减少交通拥堵以及地方和全球空气污染的政策目标提出了严峻的挑战。

英文摘要：
  Connected and automated vehicles (CAVs) are expected to yield significant improvements in safety, energy efficiency, and time utilization. However, their net effect on energy and environmental outcomes is unclear. Higher fuel economy reduces the energy required per mile of travel, but it also reduces the fuel cost of travel, incentivizing more travel and causing an energy "rebound effect." Moreover, CAVs are predicted to vastly reduce the time cost of travel, inducing further increases in travel and energy use. In this paper, we forecast the induced travel and rebound from CAVs using data on existing travel behavior. We develop a microeconomic model of vehicle miles traveled (VMT) choice under income and time constraints; then we use it to estimate elasticities of VMT demand with respect to fuel and time costs, with fuel cost data from the 2017 United States National Household Travel Survey (NHTS) and wage-derived predictions of travel time cost. Our central estimate of the combined price elasticity of VMT demand is -0.4, which differs substantially from previous estimates. We also find evidence that wealthier households have more elastic demand, and that households at all income levels are more sensitive to time costs than to fuel costs. We use our estimated elasticities to simulate VMT and energy use impacts of full, private CAV adoption under a range of possible changes to the fuel and time costs of travel. We forecast a 2-47% increase in travel demand for an average household. Our results indicate that backfire - i.e., a net rise in energy use - is a possibility, especially in higher income groups. This presents a stiff challenge to policy goals for reductions in not only energy use but also traffic congestion and local and global air pollution, as CAV use increases.
