How is own account transport well adapted to urban environments?
CRUZ, Cecilia
(2000)12, 63% of deliveries and pick-ups in the centre of Milan are own-account. The
proportion of own-account shipments is higher near the centre of cities: in a 2004 study on
the Emilia-Romagna region (Bestufs, 2006) we see that the use of own-account transport
decreases as geographic scope increases. Of all own-account shipments in this region, 51%
are in the district of Bologna, 34% in the province of Bologna, and only 15% of own-account
shipments are at the regional scale. Thus, own-account shipping is used more frequently in
dense parts of the urban area; this fact is strongly related to the business sectors which
manage their own shipping.

Timing is essential in urban freight transport: the density of commercial activity and
consumption amplifies the role of just-in-time (JIT) logistics, which are all the more valuable
in that urban environments are close to consumers. Maximum delivery leadtime requested by
clients can be a good indicator of JIT practices and requirements for tight control over freight
transport. We observe shorter maximum delivery leadtime requested on own-account
shipments: for wholesale own-account shipments within a single urban area, the mean was
1 day as opposed to 2.5 days for wholesale shipments carried out by third parties; for
industry own-account shipments within a single urban area, the mean was less than 3 days
as opposed to less than 32 days for industry shipments carried out by third parties13. This
demonstrates that own-account shipments participate more in low time limit production
systems, where clients expect rapid delivery or pick up their own orders, as in the case of the
Rungis, a wholesale market for fruits, vegetables and agricultural produce in Paris Urban
area.
For 50% of shipments of own-account transport, the maximum delivery leadtime requested is
24h versus 48h for third-party for all of activities. Reductions in shop inventory have
repercussions on intermediate links (wholesalers), who serve as a buffer between industries
reducing inventory and shops that wish to do likewise. Thus we observe that wholesalers
who rely on own-account transport for their shipments within a single urban area retain more
days of inventory: on average, 46 days as opposed to 22 days for those who use third party
shipping. Intermediaries play an increased role in this fragmented production system
(Guilbault, Gouvernal, 2010).
Transport reliability is a major issue for this kind of business. Thompson et al. (2001) remark
that retail shops have a stronger need to be supplied (for example) with fresh products,
which necessitates higher shipment frequencies, thereby increasing the number of deliveries
