Investigation of transportation innovations for food delivery and truck platoons

Abstract

Studies find that low-income areas are underserved by food retailers and have less access to healthy food, contributing to health disparities. A section of this thesis examines micromobility, drones, and ridesharing that may be suited to deliver food. Using estimated capacities and delivery speeds of several transportation modes, quantitative analysis showed that micromobility is a feasible means of delivery for short-distance, small-quantity orders. Vehicles were the only suitable option once quantity or distance increases, with trucks being the only option for large deliveries of food. Regarding trucks, autonomous truck platooning has potential benefits such as energy savings, increased capacity, and improved safety. A section of this thesis discusses the novel issue of driver behavior interacting with truck platoons in work zones. This research investigates the effects of education, platoon signage, and the number of platooned trucks using a federated simulator study. The study found that education and the use of signage showed increased driver efficiency near platoons. There was a 13 percent increase in speed and 30 percent decrease in distance following a 2-truck platoon after education. Driver speed also increased by at least 14 percent and following distance increased by at least 24 percent, with signage added. Post-simulator survey results showed drivers strongly agree that education helps to clarify how to react to platoons. 90 percent of drivers admitted it is safer to not overtake the platoon, yet only 62 percent indicated they would follow it. Using the results of this research, transportation agencies could formulate policies better accommodate truck platoons as the technology grows.
