The operationalization of electric buses in transit systems is considered the ultimate solution to eliminating transit-related Greenhouse Gas (GHG) emissions. The Canadian market, in particular, offers unique advantages to materialize the environmental benefits associated with electric buses due to the clean (very low GHG intensity) electricity generation profile. However, from a transit providers perspective, electric buses are often seen as immature technology due to the lack of supporting research. One particular aspect is the lack of research on the cascading impacts of electric bus charging stations. Unlike the traditional diesel-based bus transit operation, electric buses require on-route charging to complete the assigned operational schedule. However, current research focuses only on optimizing the sizing and the spatial distribution of the charging station network. Surprisingly, the cascading impacts and the vulnerability of such critical infrastructure network to disruption has never been researched. In addition, there is a lack of research investigating the role of Energy Storage Systems (ESS) in increasing Battery Electric Buses (BEB) infrastructure system robustness. Together, these are essential to inform the future development of autonomous charging stations and their required performance specifications.This project aims at supporting Canadian industry by developing models for quantifying the cascading impacts of electric bus charging station network under different disruption scenarios. The aim is to answer the what if? question and offer industry and transit providers research-based evidence on the behaviour of the charging infrastructure under disruptive scenarios; targeted and random. The developed models will be applied to a real-world transit network to demonstrate their practical relevance. Overall, the proposed project offers industry, transit providers, and policy-makers clear direction supporting the deployment of electric and autonomous buses and their supporting infrastructure.

电动公交车在交通系统中的运行被认为是消除与交通相关的温室气体（GHG）排放的最终解决方案。尤其是加拿大市场，由于其清洁（温室气体强度非常低）发电特性，提供了独特的优势来实现与电动公交车相关的环境效益。然而，从交通提供商的角度来看，由于缺乏支持研究，电动公交车通常被视为不成熟的技术。一个特别的方面是缺乏对电动公交车充电站的连锁影响的研究。与传统的柴油公交车运输运营不同，电动公交车需要沿途充电才能完成指定的运营时间表。然而，目前的研究仅集中于优化充电站网络的规模和空间分布。令人惊讶的是，从未研究过此类关键基础设施网络遭受破坏的连锁影响和脆弱性。此外，还缺乏对储能系统 (ESS) 在提高电池电动巴士 (BEB) 基础设施系统稳健性方面的作用的研究。总之，这些对于自动充电站的未来发展及其所需的性能规范至关重要。该项目旨在通过开发模型来量化不同中断场景下电动巴士充电站网络的级联影响，从而支持加拿大工业。目的是回答“如果？”的问题。向行业和交通提供商询问并提供有关充电基础设施在破坏性场景下行为的研究证据；有针对性和随机性。开发的模型将应用于现实世界的交通网络，以展示其实际相关性。总体而言，拟议的项目为行业、交通提供商和政策制定者提供了支持电动和自动驾驶公交车及其配套基础设施部署的明确方向。
