Public transit has long been plagued by issues such as slow, unreliable, and inefficient bus routes, especially in suburban and exurban areas. However, a group of researchers at Concordia University has proposed a groundbreaking solution in the form of On-Demand Transit (ODT). This innovative system replaces traditional buses with a fleet of passenger vans that respond to rider requests made through smart devices at bus stops. By optimizing “first-mile” trips, ODT aims to revolutionize the way commuters travel to and from work.
The Advantages of ODT
According to co-lead author Seyed Mehdi Meshkani, ODT offers numerous advantages over traditional bus-based fixed routes. From the passenger’s perspective, it improves flexibility, reduces wait times, and decreases total travel time by minimizing stops. Instead of following a set route, ODT vehicles pick up passengers at requested stops and transport them directly to the nearest public transit hub. This not only benefits passengers but also reduces capital and operating costs for transit agencies while lowering overall greenhouse gas emissions.
Case Study: Terrebonne, Quebec
To demonstrate the effectiveness of the ODT model, the researchers used the town of Terrebonne, Quebec, as a case study. Located on the North Shore of the St. Lawrence River, Terrebonne is a moderately sized suburb serviced by commuter rail and bus systems connecting it to larger suburbs like Laval and the island of Montreal. By implementing ODT in Terrebonne, the researchers were able to showcase the system’s potential without the need for physical prototypes.
ODT relies on smart devices installed at bus stops, which communicate with a cloud-based dispatch algorithm. When a passenger requests a ride, the algorithm matches the request based on factors like wait time and proximity, assigning the nearest available vehicle to pick them up. Unlike traditional buses, ODT utilizes passenger vans that require less fuel, training, and maintenance, making them a more cost-effective option for transit agencies. The comparison analysis conducted by the researchers indicated that ODT could reduce total travel time by up to 36% and detour time by 41% compared to existing bus services.
While ODT bears similarities to ride-sharing services like Uber and Lyft, it differs in its fixed cost per trip model. This unique approach ensures that passengers have a consistent and affordable commuting option without the unpredictability of dynamic pricing. As the first co-author of the paper, Ph.D. student Siavash Farazmand, noted, ODT has the potential to transform public transit and enhance the commuting experience for suburban residents across the globe.
On-Demand Transit represents a paradigm shift in the way we approach public transportation. By prioritizing efficiency, cost-effectiveness, and environmental sustainability, ODT has the power to revolutionize suburban commuting and pave the way for a more connected and accessible future. As the transportation industry continues to evolve, innovative solutions like ODT are crucial in meeting the changing needs of commuters in the 21st century.
