The traditional bus-based fixed routes that we are accustomed to may soon be a thing of the past. A group of researchers at Concordia University have proposed a revolutionary new approach to public transit that they believe could be a game-changer for suburban commuters. This innovative solution, known as On-Demand Transit (ODT), is based on the popular ride-share model employed by companies like Uber and Lyft.
ODT utilizes an algorithm-based system that replaces traditional buses with a fleet of passenger vans. Instead of following fixed routes, drivers respond to rider requests made through smart devices at existing bus stops. These drivers then pick up one or more passengers and transport them to the nearest public transit hub, such as a commuter rail or metro station. This system is designed to optimize the “first-mile” of a commute, improving passenger flexibility and reducing travel time.
According to co-lead author Seyed Mehdi Meshkani, ODT offers numerous benefits over traditional bus-based services. From the passenger perspective, it improves flexibility, reduces wait times, and overall travel time. The vehicle only stops to pick up passengers at requested stops, eliminating unnecessary delays. Additionally, transit agencies stand to benefit from reduced capital and operating costs, as well as lower greenhouse gas emissions.
The researchers chose the town of Terrebonne, Quebec, as a model for their ODT system. This suburban community is serviced by a commuter rail line and bus system, making it an ideal testing ground for the new approach. By utilizing smart devices at existing bus stops linked to a dispatch algorithm, passengers can easily request rides that are matched based on various factors such as wait time and proximity.
In addition to improving overall travel time, the ODT system could also have significant economic and environmental benefits. The use of passenger vans instead of traditional buses requires less fuel, training, and maintenance, ultimately reducing operating costs. The researchers conducted a comparison analysis that showed up to a 36% reduction in total travel time and a 41% decrease in detour time compared to existing bus-based services.
Unlike dynamic pricing utilized by services like Uber or Lyft, the cost per trip with ODT would remain fixed. This predictability could make the system more attractive to commuters looking for a reliable and cost-effective transportation option. With the potential to significantly improve the efficiency of public transit systems, ODT could pave the way for a new era of on-demand transportation.
The research conducted by the team at Concordia University presents a compelling case for the implementation of On-Demand Transit as a viable alternative to traditional bus-based services. With its potential to reduce travel time, operating costs, and greenhouse gas emissions, ODT could be the key to revolutionizing public transit in suburban and exurban communities.
