The rapid emergence of direct-to-home delivery models has quickly changed the spatial and temporal distribution of both individual travelers’ trips and of urban goods movements. A growing number of household and consumer products now being delivered directly to homes rather than being picked up in retail stores. For commercial carriers, this new last-mile is often expensive, as small shipments must be moved to geographically dispersed residences, often within increasingly constrained time windows. An emerging method of goods movement that may help to address this inefficiency is crowdshipping. Crowdshipping is a peer-to-peer delivery platform consisting of carriers and requesters.
