Since the early ’90s the Portuguese Navy has implemented several measures to improve its navigation safety performance, such as new policies, standard operational procedures, auditing and training programs, revision of course programs and certification requirements. Despite this progress, navigation accidents, remain a significant concern for the Portuguese Navy. Moreover, we still need further understanding of the effectiveness of innovative trends in marine technology over navigation safety. This paper presents an analysis of Portuguese’s naval accidents applying an adapted version of the Human Factors Analysis and Classification System-HFACS framework. Twenty navigation accidents cases were considered. The analysis shows that causality factors with higher relevance are the decision and perceptual errors, non-use or misuse of instruments (Environmental fac-tors), BRM (Personnel factors), inadequate leadership and inappropriate planning (Unsafe leadership). These findings provide an essential contribution to the revision of educational and training programs, insights for the design of bridges and navigation aids.

Young people's travel habits are important for the transition of the transport system

The transport system is facing a number of challenges due to its negative impact in areas such as the climate, equality and fairness. In a recent report, researchers highlight the voices of young people to get their thoughts on the field of transport.


Connected vehicles solve parking problems

Vehicles circulating in the city centre in search of a free parking space is a growing problem. A cloud service that tracks the traffic situation and the availability of free parking spaces could reduce both traffic and congestion.

Sustainable business travel

Almost 40 per cent of distance travelled in Sweden is business travel (including study trips) and 66 per cent of those are by car. This is therefore an area where great environmental gains can be made if more sustainable modes of transport were used.
