ROAD SAFETY AND HEALTY CITIESTHE SEIXAL CASE STUDY

BACKGROUND

CEG – IGOT – UNIVERSIDADE DE LISBOA

• 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

METODOLOGY





• 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..

FRAMEWORK





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).

FRAMEWORK





Lisboa

Lisboa by Ponte Vasco da Gama

RESULTS





Streets with, at least, 5 Pedestran Injury Crashes (PIC)

RESULTS





Streets with, at least, 5 PIC

RESULTS





• 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%).

RESULTS





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.

CONCLUSIONS





• 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

TRAFFIC CALMING MEASURES





• 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.
