A WEB-GIS for the choice of the path in the regional greenways

Risultato della ricerca: Chapter


Tourists seem less interested in the traditional sites of mass tourism, which has damaged local identities. The tourist reclaims the old function of journey, intent on widening his knowledge of the surrounding territory, while respecting the social and cultural equality of other population. This study outlines a methodology to identify the generalized cost for a system of no-motorized transport in order to determine the modal choice of users and the route of minimum cost to reach the desired destination. Within the information users, a key role is played by telematics now widely accessible through web interfaces. With the word greenways we mean the network for the no-motorized constituted by paths inserted in a natural context with particular attention to the historic and cultural patrimony of the territory. The trend of research in the field of greenways today is strongly geared towards the infrastructural design of routes. The specific studies and manuals, such as the Dutch CROW, reported mainly geometric patterns of infrastructure, design criteria for parking areas, to improve the transit of pedestrians and bicycles. From the user's perspective becomes relevant fruition with its main attributes: physical effort and safety, especially for no systematic users who may have knowledge about places but not on the tracks and their level of difficulty. In this sense, the greenways are designed both as continuous long-distance routes and as local networks suitable for systematic trips. The GIS contains layers and topological mapping with tourist and local information and network of greenways, composed by individual links with a weight corresponding to the generalized cost needed to pass, which coincides with the physical demands of the user. This effort coincides with the energy to spend to overcome all the resistance to motion characteristics of the link. The study compares the energy expressions derived from physics and kinematics with expressions of experimental nature, to obtain an expression of power required to pass through the link, indicating the degree of difficulty of the route. The user, through the ability to overlay topology, the ease of updating data provided by the GIS and the usability of the information from the web, can plan its journey across the network in response to the level of difficulty related to their physical conditions, the presence of services necessary for the trip and the natural, historical and cultural interest. Information regarding the presence of other transport (bus, rail and private transport) networks for access / egress of the network of greenways and the corresponding service (times, frequency, interchange points) are provide. The design of the network of greenways may contain, in addition to links for the exclusive use roads characterized by low emission and low speed in order to increase the capillary network The study is proposed as a further advancement, the determination of an estimation model from the user in the rate of generalized cost on the perception of traffic safety related to the situation of promiscuity with motorized traffic.
