The use of the unecological removal research scenario in recent years has been forced because of technological limitations. However, with the advent of three-dimensional modeling programs and high-fidelity graphic systems, the ability to accurately represent real-world situations in computer-generated worlds has become easier, cheaper, and more realistic. A time-to-contact (TTC) experiment is reported in which the manner of removing an approaching vehicle from the environment was manipulated. One scenario, the disappearance condition, featured a traditional, instantaneous removal of a vehicle. The purpose of this research was to determine if a more ecological research scenario, one in which the approaching vehicle becomes occluded by a naturally occurring object (the occlusion condition), influences a driver’s ability to estimate TTC accurately. The available visual information was essentially equivalent in both scenarios. If the level of ecological validity has no effect on estimates of TTC, estimates of TTC between the two scenarios would be expected to be similar. Results, however, showed estimates with 14 percent greater accuracy in the occlusion condition compared with the disappearance condition, implying that researchers have been using a research scenario that biases estimates of TTC. Further, the results of the present findings imply that there are processes that occur in real world settings that have not being accounted for in previous TTC research.

Digital technicals for the study of the Defensive Heritage: “Puerta de Almenara” and south walls of “Palacio del Gobernador” and “Plaza de Armas” of the Castle of Sagunto (Valencia)The use of digital documentation and registration techniques in Cultural Heritage is becoming more common every day, thanks to its ability to capture a large amount of data in a fast and efficient process. Its high geometric precision, thoroughness, performance retrieved and especially the generation of high fidelity and precision of architectural good assets make these tools optimal for the planimetric surveys. The work of intervention or conservation of cultural heritage requires a previous graphic registration using different techniques available. This article presents a combined method of implementation of various digital techniques that allow to achieve the most accurate graphic documentation possible. The different results obtained from the use of photogrammetry by drone or by manual camera are discussed. It is intended to seek the standardization and optimization of the process of documentation and value of the Cultural Heritage by combining these techniques. These techniques have been used in a real case: the three-dimensional modeling of various parts of the defensive set of the Castle of Sagunto (Valencia), called the “Puerta de Almenara”, which gives access to the square of the same name, on the eastern side and some walls of the fortification. The Castle of Sagunto is a mosaic of the different cultures who occupied it (Iberians, Romans, Goths, Arabs...). The fortification is located on top of a hill of the Sierra Calderona, controlling even the Mediterranean coastal road and the communication route with Aragon. During the last years, the castle has been immersed, for almost 20 years, in various works of consolidation and restoration to initiatives of the Institute of Cultural Heritage of Spain.
