Title and description of the urban freight
indicator
Units in which the indicator is measured
Number of deliveries and pick-ups per km 2 in a
zone
Loading/unloading density
Loading/unloading intensity per activity
Number of deliveries and pick-ups per activity
in a zone
Loading/unloading time
Number of hours of on street double parking for
delivery or pick-up in a zone, per vehicle,
per activity
Ratio: number of loading/unloading
Number of deliveries and pick-ups per week per
employee in an activity
Length covered for loading/unloading
Number of km for one delivery or pick-up in a
zone, per vehicle, per activity
Average length of the first trip from platform to
the delivery area
km
Average distance travelled per collection/
delivery
km per collection or delivery
Total distance travelled on roads in urban area
transporting goods by HGV, rigid lorries,
and LGV (\3.5 t) used
Total vehicle km per week in urban areas
Average time taken per delivery
Minutes per delivery
Average speed per round (including and
excluding stops to make deliveries)
km per hour
Greenhouse gas and pollution
- g pollutant per km travelled
-gCO 2 per km travelled
- litre of fuel per km according to the zone, the
vehicle, the activity
A wide range of different techniques are currently being used to collect freight
data in urban areas in Europe. These range from postal questionnaires and inter-
views to observation surveys and electronic data capture using satellite tracking
and roadside cameras.
All of the techniques currently in use are likely to remain useful in future.
However, new technology (such as satellite tracking, roadside camera and weigh-
in-motion data) has major potential to provide significant quantities of urban
freight data at relatively low cost (compared with other traditional techniques).
Consideration is required in order to determine how these new data sources and
collection techniques should be used, how they should be supplemented with other
data and how best to manage this data and integrate it with other existing data.
Although potentially very helpful, some of these new technologies do not neces-
sarily provide all the data that would have been collected in a traditional survey
(for example satellite tracking data does not provide the same amount of infor-
mation about trip purpose and type and quantity of goods carried as a trip diary
completed by a vehicle operator). In addition, some of these new technologies are
not currently allowed in some countries. For example, in Germany the use of
roadside cameras to record vehicle details is not currently legal.
