• Road accidents are present day public health problem with pedestrians being the most vulnerable
element with a global toll of 1.2 million deaths and a high economic cost. In Portugal, in 2011, 689 road
deaths, 117 (17%) of whom Pedestrian Injury Crashes (PIC). The young (20% of the population), under the
age of 20 account for 28% of victims of PIC and the senior citizens(18% of the population), under the age
of 65, 30%.
• Secondly, the coupled fact that in Lisbon Metropolitan Area the vehicles are the primary mode of travel
and travel on foot is an important method of local travel, gives place to a great number of interactions
between pedestrians and road vehicles

• Collection and analysis of statistical data, mapping in the Pedestrian Injury Crashes
locations.
• Observation at the locations of highest incidence of pedestrian accidents (≥ 5 in the
period from 2007 to 2009) to assess the local crossing conditions and the behavior of
pedestrians and drivers.
• Questionnaires to drivers with, at least, 10 years of legal authorization to drive motor
vehicles and to pedestrians of various age groups..

Seixal is a Portuguese city, and municipality, on the South bank of the Tagus River, making
part of the Lisbon Metropolitan Area (AML) and a member of the European Network of
Healthy Cities since 1998. In 2011 it had a high population density of 1 654 inhabitants /
km2, with the highest densities being found along the transport structural axis A2 (Highway
2) / EN10 (National Road 10).

• In 2007, 40.5% of the Seixal PIC occurred in signalled crossings (in Portugal, 33% in 2007 and 38% in
2011);
• The drivers have themselves as good drivers and all the other users, in general, as "bad" road users;
• There is a proven citizenship deficit in behavior, in both drivers and pedestrians, observable on the field
by the behavior of both;
• Many of the selected roads have an alignment relatively straight and practically devoid of traffic calming
measures. As a consequence, the risk of excessive speed is potentiated.
• There is a collective awareness that the elderly and children are the most vulnerable group of
pedestrians;
• Statistically, we highlight the fact that, in 2007, 36% of PIC, in the EN10, on the parish of Amora, involved
young people aged between 9 and 19 years and occurred between 07:45 and 18:30. We also highlight the
fact that PIC involving the elderly citizens happen, mainly, between 7 and 15 hours (70%).

The results of the survey show that about 19-28% of PIC that occurred in Seixal happened in the center of
Paivas / Cruz de Pau. This appears to be the result of a noxious combination of a trunk road with a densely
populated area. The conflicts are further enhanced by location of a large number of functional units in the
area.

• Attitudes are not a negligible factor on Pedestrian Injury Crashes in Seixal;
• The inadequacy of the urban circulation space and the lack of measures for its regulation and
organization was another factor not negligible;
• We emphasize the existence of a regional structuring road (EN 10), integrated in the urban fabric,
creating conflicts between drivers and between drivers and pedestrians;
• It is important to identify the main pedestrian and vehicular flows to be able to create safe routes for
pedestrians and reduce conflicts between pedestrians and drivers (and among drivers themselves);
• It is important the adequacy of public transport to these flows and to promote its use;
• The application of traffic calming measures, by adaptation to the vehicular and pedestrian flows, are a
cost-effective way to achieve the reduction of accidents.
TRAFFIC CALMING MEASURES

• Vertical deflections – Very effective but
restricted to low hierarchy streets due to the
induced capacity constraints of the speed
reduction .
• Horizontal deflections – With a lower speed
reduction effect are more appropriate to main
arteries-
• Narrowing – Studies show that speed tends to
reduce with the narrowing of the lanes

• Blocking through traffic – In a road hierarchy
scheme this will force the through traffic to
pass through a designated set of through
roads.
• Landscaping – Used in conjunction with other
traffic calming measures, not only helps to
provide a safer environment but makes it
more friendly and enjoyable.
• Signalling and road markings improvement –
Sometimes this tend to be neglected, namely
the road markings, but they play an important
role in road safety.
