Abstract Cities are continually evolving through adjustments to zonings. The potential to integrate more equitable and effective value capture mechanisms into the rezoning process makes estimation of increases in land value from rezoning of interest to urban planners. The use of Residual Land Valuation (RLV), while accepted practice in development feasibility calculations, tends to be absent from the rezoning process because it is outside the skill set of most planners. Also, RLV has historically been applied to individual land parcels with limited potential for wider estimation of land value, and is generally not embedded in planning tools limiting the potential for value capture mechanisms to be included in the early scenario phases of rezoning decisions. This study addressed these issues. An RLV tool to estimate value uplift from rezoning was developed and embedded into a planning support system called Rapid Analytics Interactive Scenario Explorer (RAISE) to explore densification options associated with transport-oriented development. The co-design of the RLV tool with end-users and its test in a real case scenario in Greater Sydney has demonstrated the potential of RAISE-RLV. Specific advances included development of an algorithmic approach to RLV, that could be automated and applied across multiple parcels of land in rapid response to changing zoning. Second, such calculations were incorporated into a platform compatible with established rezoning decision making processes. The study demonstrated that it is possible to include RLV in a platform that improves users' understanding of the valuation process. The RAISE-RVL approach and tool can make a significant contribution to well-considered urbanisation. In addition, in the current era of tight government budgets, properly informed value capture mechanisms are a promising strategy for funding new infrastructure supporting both urban growth and the broader goals that growth can realise.

一种快速分析工具，用于映射重新分区对房产价值的影响

摘要 城市通过对分区的调整而不断发展。将更公平和有效的价值获取机制整合到重新分区过程中的潜力使得对城市规划者感兴趣的重新分区的土地价值增加进行估计。剩余土地估价 (RLV) 的使用虽然在开发可行性计算中是公认的做法，但在重新分区过程中往往没有，因为它超出了大多数规划者的技能范围。此外，RLV 历来应用于单个地块，其更广泛地估计土地价值的潜力有限，并且通常不嵌入规划工具中，从而限制了将价值捕获机制纳入重新分区决策的早期情景阶段的潜力。本研究解决了这些问题。开发了一个 RLV 工具，用于估计重新分区带来的价值提升，并将其嵌入到一个名为 Rapid Analytics Interactive Scenario Explorer (RAISE) 的规划支持系统中，以探索与面向交通的开发相关的致密化选项。RLV 工具与最终用户的共同设计及其在大悉尼的真实案例场景中的测试证明了 RAISE-RLV 的潜力。具体的进步包括为 RLV 开发一种算法方法，该方法可以自动化并应用于多个地块，以快速响应不断变化的分区。其次，此类计算被纳入与已建立的重新分区决策流程兼容的平台中。该研究表明，可以将 RLV 包含在一个平台中，以提高用户对估值过程的理解。RAISE-RVL 方法和工具可以为深思熟虑的城市化做出重大贡献。此外，在当前政府预算紧张的时代，适当知情的价值获取机制是为支持城市增长和增长可以实现的更广泛目标的新基础设施提供资金的有希望的战略。
