Perception of environment in front of driving vehicle is a core investigation theme of intelligent vehicle technologies aiming to increase safety, convenience and efficiency of driving. Using stereo vision for environment perception is a hot technology. This paper developed an algorithm for stereo matching in intelligent vehicle application. The experimental results indicate that this algorithm is effective. Furthermore, this algorithm paves the way for the implementation of automotive driver assistance system.

General Opinion

Within the context of promoting the “healthy routes” program, the aim of this study was to validate the urban walkability perception questionnaire (UWPQ) in the Balearic Islands to determine the characteristics of the urban environment that promote walking among the population. The UWPQ measures pedestrian facilities, infrastructures of the environment, perception of safety and a participant’s general opinion. This process was performed in 12 routes predefined by a community participation program and set around the primary health centers. Degree of correlation between the items was calculated. The final internal consistency was 0.8 in all blocks according to the Cronbach’s alpha test (p < 0.01). Goodman and Kruskal–gamma correlation coefficient (γ) between the item measuring the general opinion and the rest of the items was significant. The items from the perception of safety and pedestrian facilities blocks were the ones that most affected the final assessment. Those regarding the pedestrian-only pavements, clearly marked pavements, noise, traffic density and parks condition obtained the lowest coefficients. To conclude, the results showed that the UWPQ is a suitable instrument to assess the degree of adequacy of the urban environment for walking. It could contribute to create healthy environments as well as to improve public policies.

The article is devoted to the architectural sphere development key idea as one of the main tourist interest components. The article tells us that today it is increasing the importance of the visual urban environment perception and impressions, tourist social experience forming. These conditions provoke a significant meaning of architecture as an attractor. Modern requirements dictate the introduction of modern marketing management mechanism architectural forms need, including their optimal using in the tourism industry. It contents a lot of world and domestic practice examples. It mentions a special interest to the architectural forms creation processes and modification on the purposes of it integration in tourism. These processes could be realized through the urban environment museumification, remake-building constructing, the unrealized architectural projects implementation, architectural reset&#34;, as well as through the design of new attractions.
