As communications technology innovations continue to rapidly transform retail supply chains, novel solutions are required to reduce transportation network impacts from ubiquitous last-mile shipments.

Crowdshipping provides one potential approach to address resulting inefficiencies and redundancies in these local and last-mile deliveries.
