Smartcard-based public transit systems have been widely adopted across many cities around the world. These systems generate large volumes of transaction records from individual passenger trips and contain the requisite information that enable the mapping, measurement and monitoring of fare equity. In this paper, we propose and apply new measures to evaluate fare equity using smartcard data to map changes in fare equities following a fare policy reform across a major metropolitan region in Australia. Smartcard data is used to first reconstruct individual travel trajectories on which we compute our measures to explore two dimensions of equity: (1) ‘horizontal’ (for all passengers) versus ‘vertical’ (different types of passengers); and, (2) ‘global’ (across the entire transit network) versus ‘local’ (for a specific travel zone). Results reveal that in the first dimension the fare policy reform led to more equitable fares with the effect of diminishing spatial variations under the old policy for all types of transit passengers (adults, children, seniors and concession card holders); however, the impact of this fare policy reform reflected in the second dimension is subject to the number of zones travelled, residential location of passengers, the number of journeys made within the week and the applicable incentives. Finally, we draw on our empirical approach to report on a prototype dashboard through which public transit agencies have the capacity to map, measure and monitor how ridership translates to fare equities. More generally, we highlight the capacity of smartcard data, when embedded within our empirical framework, to better inform smarter policy around fare reforms in order to achieve greater equity across service populations.

基于智能卡的公共交通系统已在全球许多城市中广泛采用。这些系统从各个旅客的行程中生成大量交易记录，并包含必要的信息，这些信息可用于映射，度量和监控票价公平性。在本文中，我们提出并应用了新的措施，以通过智能卡数据评估票价权益，以绘制澳大利亚主要大城市地区的票价政策改革后的票价权益变化。智能卡数据用于首先重建个人旅行轨迹，然后我们在该轨迹上计算我们的度量以探索公平的两个维度：（1）“水平”（针对所有乘客）与“垂直”（不同类型的乘客）；（2）“全球”（在整个公交网络中）与“本地”（针对特定旅行区域）。结果表明，在第一方面，票价政策改革导致票价更加公平，在旧政策下，针对所有类型的过境旅客（成人，儿童，老人和优惠卡持有人）的空间变化减少了；但是，第二方面反映的票价政策改革的影响取决于旅行区域的数量，乘客的居住地，一周内的旅行次数以及适用的激励措施。最后，我们采用经验方法在原型仪表板上进行报告，公共交通部门可以通过该仪表板来绘制，测量和监视乘车率如何转换为票价权益。更笼统地说，当我们将智能卡数据嵌入到我们的经验框架中时，我们会着重强调这些功能，
