The traditional bus-based fixed routes used by public transit agencies have long been plagued by issues such as slow and unreliable service, leading researchers to explore new approaches to transportation. A group of researchers at Concordia University has proposed a groundbreaking solution in the form of On-Demand Transit (ODT) – an algorithm-based system that aims to transform the way suburban commuters travel to work.
ODT replaces traditional buses with a fleet of passenger vans, which respond to rider requests made through smart devices installed at existing bus stops. This innovative approach aims to optimize “first-mile” trips, where passengers travel from their homes to the nearest public transit hub, such as a commuter rail or metro station. By collecting multiple passengers at requested stops and delivering them to the transit hub, ODT streamlines the commuting process and reduces overall travel time.
Co-lead author Seyed Mehdi Meshkani highlights several advantages of the ODT system. From the passenger’s perspective, ODT offers increased flexibility, reduced wait times, and improved overall travel time. Additionally, the system benefits transit agencies by reducing capital and operating costs, as well as lowering greenhouse gas emissions. This shift towards a more efficient and sustainable transportation model has the potential to revolutionize public transit in suburban and exurban communities.
Case Study: Terrebonne, Quebec
The researchers used the town of Terrebonne, Quebec, as a model for their ODT system. Situated on the North Shore of the St. Lawrence River, Terrebonne is a moderately sized community with existing commuter rail and bus connections to larger suburbs and Montreal. By analyzing Terrebonne’s transportation needs, the researchers were able to demonstrate the feasibility and benefits of implementing the ODT system without the need for physical prototypes.
The ODT model relies on smart devices at bus stops connected to a cloud-based dispatch algorithm. This technology enables passengers to request rides, which are then matched based on factors such as wait time and proximity. The use of passenger vans in the ODT system offers several advantages over traditional buses, including lower fuel consumption, reduced maintenance costs, and increased operational efficiency. The comparison analysis conducted by the researchers revealed significant reductions in total travel time and detour time compared to existing bus-based services.
Unlike dynamic pricing models used by ride-sharing services like Uber and Lyft, ODT maintains a fixed cost per trip for passengers. This pricing structure ensures affordability and predictability for commuters, while also promoting the sustainability of the transportation system. The ODT model represents a shift towards a more environmentally friendly and cost-effective approach to public transit, with the potential to transform the way suburban commuters travel to work.
The On-Demand Transit model presents a promising solution to the challenges facing traditional bus-based fixed routes. By leveraging innovative technology and optimizing passenger transportation, ODT has the potential to revolutionize public transit in suburban and exurban communities. With its focus on efficiency, cost savings, and sustainability, the ODT system represents a new era in transportation that prioritizes the needs of both passengers and transit agencies.
