NAVIGABLE DATABASES FOR INTELLIGENT TRANSPORTATIONSYSTEMS: CREATION AND MAINTENANCE OF THE SPANISHDATABASE

摘要

Creation of digital cartography is nowadays an activity many companies can develop, but whenwe add the concept “navigable” then the complete magnitude of the problem is appearing.Aspects like what are the sources that can be used, how to collect the traffic information, how tocode the information into a database are some of them to be solved. It is even more complexwhen the task must be developed into a standard and homogeneous process in more than 25countries world wide, of which 14 in Europe. From a business perspective, the optimization offieldwork, the technology tools to collect information in real time on the field, increasing theefficiency and controlling the costs are some of the continuous challenges to solve. The newtechnology advances on creating the databases that will help the existence of more intelligentsystems that can make use of them, but also will allow real time updating systems with dynamicinformation, like for example the TMC codes with traffic information. Finally the work done isconverted into a digital database with coverage in terms of population and number of cities with acompletely navigable geometry based on streets and roads with traffic attributes incorporated(over 150 attributes per road segment).This work has significantly improved the reliability of Navigation Systems and will allow thedevelopment of many applications within the vehicle to increase comfort level and optimizeperformance. But the introduction of state of the art technology into the data collection and database creation processes has also helped in drastically increase the efficiency on creating andupdating such databases. Intelligent Transportation Systems will take advantage of the nextgeneration of navigable databases.
