“…The displacementbased equations are then differentiated twice to obtain acceleration. This model was implemented in Mathematica 7.0 (Wolfram Research, Inc.) and provides a fast, first estimation of vibration levels at locations beyond the limits of the data gathered (see, Salvador et al, 2011;Real et al, 2011). data set.…”

“…The effect of quasistatic loads can be introduced as a dynamic overload with a null characteristic angular frequency, as stated by [13] or following the Zimmermann formulation, as described by [17]. Because of computational time reasons, in this paper the second procedure will be followed.…”

In recent years, there has been a significant increase in the development of the railway system. Despite the huge benefits of railways, one of the main drawbacks of this mode of transport is vibrations caused by vehicles in service, especially in the case of trams circulating in urban areas. Moreover, this undesirable phenomenon may be exacerbated by the presence of irregularities in the rail-wheel contact. Thus, an analytical model able to reproduce the vibrational behavior of a real stretch of tram track was implemented. Besides, a simulation of different types of corrugation was carried out by calculating in an auxiliary model the dynamic overloads generated by corrugation. These dynamic overloads fed the main model to obtain the vibrations generated and then transmitted to the track.

“…In new urban districts, the distance to the stop is 800-1000m. In addition, the distance to transferring station by bike or by bus is less than 2 kilometers, from which we can determine that the attract range outside central city is 2km on both sides [3] . Therefore, the attract range of a modern tram line in new urban district can be approximately determined within 2km on both sides and attract range of a stop is 2km.…”

This paper presents the measurement index system of tramline network on the basis of the defining of its scale of modern trams. The author makes a comprehensive measurement for the line network scale of modern trams in new urban districts by using measurement theory. Based on the uncertainty mathematic methods, the author sets up a comprehensive measurement model for the line network scale of modern trams in new urban districts, taking Hexi District in Nanjing as an analysis case. The results show that the comprehensive measurement model can accurately define the line network scale of modern trams in new urban district.
