Abstract: | Emerging technologies and business models have contributed to the improvement of transportation systems and services towards a more sustainable approach to mobility. Shared mobility has become widespread as a viable solution to the increasing demand for transportation. Many cities worldwide have implemented shared mobility service and demonstrated that it could offer numerous environmental and operational benefits. However, their implementation in rural and suburban areas that feature lower population density and dispersed travel demand is not receiving the same attention. This research considers four suburban communities to evaluate the operation of a fleet of shared mobility as a potential substitute for the currently fix-route public transportation services. For each area, four scenarios were defined to consider different powertrain technologies. These scenarios include the Internal Combustion Engine, Battery Electric, and two Autonomous Electric Vehicles scenarios. While assessing the efficiency of the fleet composition system, four vehicle sizes are considered. Further, an optimized routing solution for serving the known travel demand is utilized to calculate the total cost of fleet ownership, which accounts for the purchase price, energy consumption, CO2, and driver labour costs. The results highlight potential benefits of adopting a fleet of shared Autonomous Electric Vehicles for the case studies and show approximately 67-68% and 69-70% savings compared to a shared fleet of conventional and Battery Electric vehicles, respectively, mainly due to the omission of the driver costs. In the absence of operationally safe Autonomous Electric Vehicles, the more conservative scenario of employing a fleet of shared Autonomous Electric Vehicles with the presence of safety attendants could result in 6-8% and 13-14% savings compared to a shared fleet of conventional and Battery Electric vehicles. Nevertheless, the results indicate low utilization rates for the fleet attributed to the inconsistency in demand throughout the day. The results provided in this research can inform policymakers and service providers and be used for further evaluations of such transportation services. |
