“…In this topic, simple and practical research has been very dynamic, and it is only recently that the benefits in real applications are incorporated. Assimilation of investigated findings into decision making for public policy has been slow, but it is going now more rapidly, basically due to recent environmental and transportation legislation and associated research investments in the majority of the industrialised world [23].…”

Although the individuals" transport behavioural modelling is a complex task, it can produce a notable social and economic impact. In this paper, Fuzzy Cognitive Maps are explored to represent the behaviour and operation of such complex systems. An automatic approach to extract mental representations from individuals and convert them into computational structures is defined. For the creation of knowledge bases the use of Knowledge Engineering is accounted and later on the data is transferred into structures based on Fuzzy Cognitive Maps. Once the maps are created, their performances get improved through the use of a Particle Swarm Optimisation algorithm as a learning method, readjusting its predicting capacity from stored scenarios, where individuals left their preferences in front of random situations. Another important result is clustering the maps for knowledge discovery. This permits to find useful groups of individuals that policymakers can use for simulating new rules and policies. After related maps are identified, to merge them as a unique structure could benefit for different usages. Therefore an aggregating procedure is elaborated for this task, constituting an alternative approach for selecting a centroid of a specific estimated group, and therefore having, in only one structure, the knowledge and behavioural acting from a collection of individuals. Learning, clustering and aggregation of Fuzzy Cognitive Maps are combined in a cascade experiment, with the intention of describing travellers" behaviour and change trends in different abstraction levels. The results of this approach will help transportation policy decision makers to understand the people"s needs in a better way, consequently will help them actualising different policy formulations and implementations.

The travel demand was calculated by multiplying the at-risk population by the participation rate.Based on the findings of previous hurricane evacuations fromCharleston (US ACE 2003), this study assumed that all residents of storm surge areas and mobile homes were evacuated and that evacuees used 65 Á 75% (US ACE 2003) of the vehicles available in each household.…”

Limited specific evidence is available on the effectiveness of using contraflow as an evacuation traffic management tool. This study was conducted to determine the best combination of strategy options for evacuating Charleston, SC, along route I-26 during the event of a hurricane or other events. PARAMICS microscopic traffic simulator was used to evaluate the impact of each combination of evacuee response timing and traffic control strategy, such as contraflow, with respect to average vehicular travel time and evacuation duration. Analysis revealed the combination of management strategies that created the lowest evacuation durations and travel times for several types of anticipated evacuee responses. Furthermore, a proposed reconfiguration of the I-526/I-26 interchange for contraflow operations produced additional savings in travel times and evacuation durations. These findings support the use of all lanes for contraflow during all evacuations and provide justification to examine a possible reconfiguration of the I-526/I-26 interchange for use during evacuations.

“…Outside of the federal government, experts and stakeholders also have noted the need for more effective transportation security to deal with the terrorism threats the United States faces in the early 21st century (AASHTO 2002;Fries et al 2008;Helmick and Compton 2004;Johnston 2004;Meyer 2008;Mitchell et al 2004). Because potential threats are present in train and bus stations, ports, platforms and waiting areas, and on surface and maritime vehicles, all surface transportation workers need some training in the recognition and assessment of potential hazards and dangerous activities, as well as response and notification protocols in the event of an incident or evacuation.…”
