Planning for the Unknown? Modeling is a Must.

Zero-emission buses (ZEBs) provide communities with a wealth of benefits, from cleaner air to quieter roads. However, while this blossoming technology continues to evolve, operators must be prepared for new constraints to range, extended charging or refueling times, and infrastructure upgrades necessary to support a resilient and clean fleet.

The performance of ZEBs is influenced by a wide array of factors that are not often accounted for in advertised specifications. For this reason, ZEB performance modeling tools are used to provide operators with insight into vehicle performance within their unique geographies and climate. ZEB performance modeling offers refined estimations of the minimum fleet size without impacting service levels. It also helps shape recommendations on the best charging strategies and charging infrastructure necessary to support the new fleet. Lastly, it provides the necessary information to support a staged implementation of the fleet transition.

The WSP ZEB Planning teams have used their proprietary modeling tools as part of a suite of services to support transit agencies and private fleets worldwide in their transitions towards electrification. We work with transit agencies from all sizes, and our tools have supported Los Angeles Metropolitan Transportation Authority (LA Metro), San Francisco Municipal Transportation Agency (SFMTA), and Massachusetts Bay Transportation Authority (MBTA). Through this experience, we have revealed some of the greatest barriers to ZEB fleet transitions and met them with creative solutions carved from unparalleled experience. 

This presentation will describe the importance of performing ZEB modelling early in the electrification process to meet transition timelines. During this session, we will discuss the philosophy and approach of the model and considerations for inputs and outputs, along with lessons learned from previous experience.

This session will run 25 minutes, inclusive of Q&A.

This session is on the Main Route - Afternoon.




Shantelle Dreamer

Shantelle Dreamer is a sustainable transportation planner supporting public and private fleets in the transition to zero-emission technologies. Her work involves a holistic approach in which she applies performance modeling tools, ongoing technology assessments and cross-industry relationships to build resilient transition strategies tailored to the needs of each client. Through her experience with a national client base, including San Francisco Metropolitan Transit Authority (MUNI), Regional Transportation District Denver (RTD), and Maryland Transit Administration (MDOT MTA), Shantelle has come to understand the challenges that are unique to each region as well as the barriers that are ubiquitous across the country. When she is not striving to create more breathable air, Shantelle can be found rocking on the drums or hiking through wildflower meadows near her mountain home in Boulder, CO.

Anaïssa Franca

Anaïssia Franca is a Senior Consultant with WSP’s Transportation Advisory Services. She is specialized in techno-economic analysis of alternative propulsion systems for public transport and heavy-duty vehicles and has worked on numerous fleet electrification projects across North America. While completing her master’s thesis, she developed one of the most precise electricity consumption modelling tools in the market which calculates energy consumption, operating costs and emissions reductions related to the adoption of zero- emission electric buses. Many transit agencies across Canada, including Translink in Vancouver and the TTC in Toronto, have utilized this tool to support their transition to a zero-emission fleet and their pilot projects, such as the Pan Canadian Electric Bus Demonstration and Integration Project. As a result, Anaïssia has a broad knowledge of new trends in the electric vehicles sector across Canada in terms of the technology, operations and planning.

Since joining WSP, Anaïssia has worked on key and complex projects involving electrification roadmap planning and infrastructure upgrades required to electrify small to large fleets. Based on her modelling expertise, she also works on the continuous improvement of BOLT, WSP’s proprietary tool that calculates energy requirements and peak demands for fleets with different charging strategies.
