In short term there will be two new roads, one is the VCI that creates a bypass around Alcobaça,
solving partially of the problem previously pointed out and another is road to be built is the IC9,
which will bring a new concept of accessibility, since it is an important East/West structure,
making much easier some of the actual connections, specially at the Regional level.
Other attributes of the network were analysed such as, flows and accidents, making possible to
identify some of the black spots of the network and the main accident causes (Figure 5).
10 Principal Causes of accident in Alcobaça Municipality
Figure 5 - Main causes of road accidents
An analysis to the charts from figure 5 allows identifying that excessive speed and yielding
disrespect as main causes for accidents. However, excessive speed may result from driver
abuse, while accidents caused by yield disrespect, may be as well caused by driver abuse or may
be due to road conditions. In fact, interceptions without the minimum visibility distance are
common in Alcobaça.
Finally connectivity analyses were made to the network, resulting that all the main connections
could be fulfilled, except one. The Benedita parish did not have any reasonable connection at a
regional level, for instance a connection to A8. Since is one of the most important parishes of the
region, with a strong economy, this in an important gap at the network.
