Resumen
Urban Transport systems in big cities face many challenges because of continuous growth of the urban population, amount of cars and general overload of the public transportation. Challenges which the urban transport is facing have consequences for households, businesses and the whole urban community. Urban transportation takes a special part in linking economic growth and collective development as well as extensive negative impact on citizens? health and surrounding environment. Many financial institutions and governments support cities and countries in their endeavor to build and improve transport infrastructure and systems to solve above issues. Within the other modern cities also Kraków with its almost 800 thousand people population is being challenged also in this regards. During the recent decades there has been done a major change in its urban transportation network. Trams rails network with a modern tram machines was defined as the one of the most important for the system. In Kraków the project is called ?Krakow's Fast Tram?. Along with this extraordinary development there needs to be adopted and efficiently used a way to verify and maintain transportation infrastructure. Among the others the laser scanning with its incredible functionality and speed is becoming an answer for this demand. In the lane with data capturing the proper data management and access is coming. The authors used and underlined a big benefit of the combination of available metrology techniques including accurate total station measurements, laser scanning and GPS positioning. The project was started by measuring the Fast Tram Tunnel in Kraków with techniques mentioned above. The next step was to post process the data and assure proper quality so it can be used in all disciplines. To illustrate this innovative combination of techniques and possible use for various disciplines there has been prepared verification of transition curve, circulation curve, track gauge, cant and other parameters which are standard deliverables for tram track geometry studies. On the other hand the scan data management portal has been created with scan data available through the web site regardless the location. Finally with regards to the rapid development of the city infrastructure and community it is extremely important to use all currently available measuring techniques in an efficient and modern way which has to be fast and flexible enough to cope current demands. In this particular study laser scanning together with other surveying and analytics techniques helps to verify and maintenance tram infrastructure in urban transportation today and very likely will be the best method as well in the future.
