Last mile (transportation)

Bicycle sharing systems such as Capital Bikeshare have been cited as a way to alleviate the "last mile problem."

Last mile is a term used in supply chain management and transportation planning to describe the movement of people and goods from a transportation hub to a final destination in the area.

Usage in distribution networks[edit]

The term "last mile" was originally used in the telecommunications field but has since been applied to supply chain management. Transporting goods via freight rail networks and container ships is often the most efficient and cost-effective manner of shipping. However, when goods arrive at a high-capacity freight station or port, they must then be transported to their final destination. This last leg of the supply chain is often less efficient, comprising up to 28% of the total cost to move goods. This has become known as the "last mile problem."[1][2] The last mile problem can also include the challenge of making deliveries in urban areas where retail stores, restaurants, and other merchants in a central business district often contribute to congestion and safety problems.[1][3]

A related last mile problem is the transportation of goods to areas in need of humanitarian relief. Aid supplies are sometimes able to reach a central transportation hub in an affected area but cannot be distributed due to damage caused by a natural disaster or a lack of infrastructure.[4]

As e-commerce continues to grow, the last leg of delivery, ending up at the consumer's home or business, has become more challenging. Since most consumers are away from home when deliveries are usually made, unattended delivery has become a significant issue among delivery companies like UPS, FedEx, USPS, DHL, and others. Leaving a parcel unattended exposes the item(s) to weather, and to the increasing chance of theft by "porch pirates" (a person or persons who steal packages off of unsuspecting customers' porches or front door areas). Retail companies like US based Amazon and Chinese base Alibaba have researched and deployed the use of drones to delivery online purchased goods to consumers.[5] Amazon has also set up lockers and some urban centers as a way of consolidating packages. The Consumer Electronic Show in January, 2015, featured one company, TrackPIN which has developed a cloud-based garage keypad that can connect a garage to UPS or FedEx to have it automatically generate a unique, one-time use code so their package can be delivered under their garage door.[6]

Usage in transportation networks[edit]

The Hiriko folding two-seat urban electric car will be deployed in Germany in 2013 to provide the last mile of the journey to Deutsche Bahn's railway customers to their final destinations.[7]

"Last mile" has also been used to describe the difficulty in getting people from a transportation hub, especially railway stations, bus depots, and ferry slips, to their final destination. When users have difficulty getting from their starting location to a transportation network, the scenario may alternatively be known as the "first mile problem."[8] These issues are especially acute in the United States where land-use patterns have moved more jobs and people to lower-density suburbs that are often not within walking distance to existing public transportation options. Therefore transit use in these areas is often less practical. Critics claim this promotes a reliance on cars, which results in more traffic congestion, pollution, and urban sprawl.[9][10]

Traditional solutions to the first mile problem in public transit have included the use of feeder buses, bicycling infrastructure, and urban planning reform.[9][11] Other methods of alleviating the last mile problem such as bicycle sharing systems,[8] car sharing programs,[12] pod cars (personal rapid transit),[13] and motorized shoes[14] have been proposed with varying degrees of adoption. Bicycle sharing programmes, however, have been widely successful in Europe and Asia, and are beginning to be implemented on a large scale in North America.[15][16] [17]
