In TIA research we often encounter the problem of increasing amount of data that is necessary for detailed investigation and analysis, as the scale of commercial developments become larger and more complex. As a result, TIA presents two problems. The first problem is the difficulty of data acquisition. The second problem is the reliability of data. As a solution, we developed an integrated database system.}, subject = {Verkehrsplanung}, language = {en} } @article{Rose2004, author = {Rose, Martin}, title = {Modeling of Freeway Traffic}, doi = {10.25643/bauhaus-universitaet.263}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20111215-2639}, year = {2004}, abstract = {An integrated modeling of freeway traffic is developed, whose implementation in an uniform computer -aided simulation model facilitate comparative evaluation and systematic coupling of several traffic simulations, traffic controls, traffic measurements and traffic scenarios.

As a result of many simulation analyses, it is shown that automobiles need much more traffic space in comparison with the transit as is shown by the proposed traffic space ratio both in CBD and along the corridor.}, subject = {Verkehrsplanung}, language = {en} } @article{SemenovBazhanMorozov2004, author = {Semenov, Vitaly and Bazhan, Andrew and Morozov, Sergey}, title = {Distributed STEP-Compliant Platform for Multimodal Collaboration in Architecture, Engineering, and Construction}, doi = {10.25643/bauhaus-universitaet.261}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20111215-2616}, year = {2004}, abstract = {This paper presents an innovative software platform OpenSTEP intended to build advanced distributed integrated systems and to conduct multidisciplinary collaborative projects in both academy and industry.
