World's Major Cities and the Logistics Performance Index, 2010
The logistical performance of urban freight distribution requires a
comparative framework and key performance indicators. However, such a
framework does not yet exist, but one has been compiled at the national
level by the World Bank; the Logistics Performance
Index (LPI). While the LPI reflects global trade and supply
chains, it can also be reflective, to some extent, of the logistical
capabilities of cities. By cross-referencing a dataset composed of the
world's 435 cities of more than 1 million inhabitants (totaling 1,257
million) with their respective national LPI values it is possible to categorize cities by
their nation's LPI. 27% of the urban
population lived in cities within countries with a low LPI (less
than 3) while 47% lived in cities with below average LPI conditions
(between 3 and 3.5). Only 26% of the urban population were
living in cities with adequate national LPI conditions (more than 3.5).
In countries with high LPIs, such as the United States, supply chains
tend to be extensive and covering large markets areas, while in
countries with low LPIs supply chains tend to be shorter and more
unreliable. This is also reflected in city logistics with cities in high
LPI countries having extensive urban freight distribution systems while
cities in countries with low LPIs having urban freight distribution
systems that a more simple and inefficient.
Such an assessment should be interpreted with caution as significant
differences may exist between cities of the same nation. For instance, port and airport cities tend
to have more capabilities for city logistics because of their
infrastructure and distribution capabilities.
