SMAT2008R24RESEARCH CONCERNING DETERMINATION OF COMMERCIALSPEED IN ORDER TO VALIDATE THE OPPORTUNITY TO INTRODUCEA NEW PUBLIC TRANSPORT SYSTEM ON INDIVIDUAL LANE (WHEELTRAMWAY) WITHIN THE METROPOLITAN AREA OF PITESTI CITYFlorian IVAN, Rodica NICULESCU, Viorel NICOLAE, Catalin ZAHARIAAbstract: In the first part of this paper it is defined the general concept of commercial speed, respective the averagecommercial speed, as a parameter of technical and economical analyze for a certain itinerary, within a public transportsystem by regulated duty. In the second part of the paper it is deployed a calculation model that emphasizes theinterdependence between the values of this parameter and the particularities of road traffic within the analyzeditinerary. The calculation model was applied by authors to make the opportunity study for introducing a new publictransport system on individual lane (wheel tramway) within the metropolitan area of Pitesti city..Keywords: commercial speed, average commercial speed, road traffic, public transport system, wheel tramway.Ivan Florian, Prof.PhD.eng., University of Pitesti, Automotive Department, e-mail:florianivan2002@yahoo.com, tel. +40-248-218804/254.Niculescu Rodica, Lecturer PhD.eng., University of Pitesti, Automotive Department, e-mail:rodica.niculescu@upit.ro, tel. +40-248-218804/254.Nicolae Viorel, Prof.PhD.eng., University of Pitesti, Automotive Department, e-mail:viorel.nicolae@upit.ro, tel. +40-248-217736.Zaharia Catalin, Lecturer PhD.eng., University of Pitesti, Automotive Department, e-mail:catalin.zaharia@upit.ro, tel. +40-248-218804/254.SMAT2008R25EXPERIMENTAL RESULTS OF THE IMPACTBETWEEN A FALSE-HEAD AND THE INSTRUMENT PANELSorin ILIE, Ştefan TABACUAbstract: The paper presents the conception, design and construction processes of a test rig dedicated to theexperimental study of the impact between a false-head and the instrument panel. Also, there are presented someexperimental results and their comparison with a simulated test of the head impact with the instrument panel.Keywords: instrument panel, head impact, ECE 21 Regulation, head deceleration, gravitational pendulum.Ilie Sorin, Eng.
