“…Jakimavičius and Burinskienė (2010) investigated vehicle flow optimization methods and their application possibilities when informing traffic us-ers about the situation in the city, and in their article (Jakimavičius, Burinskienė 2009a, 2009b) presented the rating system of the Vilnius city residential areas by using expert methods and pointed out the residential areas with the highest traffic volumes of the city. Kliukas et al (2008) investigated the impact of vibrations caused by vehicles on buildings with the aim to preserve cultural values in the city of Vilnius. Frequencies 1.3 and 10.8 Hz are presented as dangerous.…”

Road traffic flows on a straight road segment are modelled in this article. The mathematical model of traffic flows has been constructed by using the method of lumped parameters. CO 2 , CO, CH, NO x , PM regression equations of internal combustion engines' (ICE) emission has been developed. The accuracy of regression equations is 0.98÷0.99. The article presents assumptions for constructing the mathematical model, description of the mathematical model and gives simulation results. Traffic flow parameters, such as traffic flow concentration and traffic flow speed are presented as modelling results. ICE emission depending on the concentration and traffic flow speed are presented as well.

“…The use of models of infinite length has been proposed (Hunt 1995). A review of the available literature indicates that there is a significant absence of current research in this area, as the existing work is oriented towards solving specific problems (Kliukas et al 2008;Crispino, D' Apuzzo 2001;Vanagas et al 2017). The transmission of vibrations are significantly affected by the type of the load-bearing system of a building, the materials that are used for its construction, the type of the foundation, the existence of a basement and the soil mechanical characteristics.…”

During the operation of urban subway rail transit systems, vibrations are generated that transmitted through the soil, induce vibrations in nearby buildings. The transmission of ground-borne vibrations from subway rail transit systems in a building is governed by the soil-foundation interaction, the reduction of vibration level between floors, and the amplication due to resonances of building elements. These are influenced by the type of the building, its construction materials, the foundation soil, and the frequency content of the excitation. A methodology is proposed for the determination of the sound vibration along the height of the building for a specic construction type, demonstrating how the attenuation and amplication parameters can be calculated. For this particular building type, a notable amplication of the vibration due to floor and other structural resonances was found, whereas the vibration and hence the radiated noise levels are similar from the first floor up. An overall building amplication factor is proposed, taking into account all the above mentioned transmission mechanisms.

Summary Traffic‐induced vibration is one of the main causes of small (often only cosmetic) damages for Heritage buildings. The heavy public road‐transport, often very close to these structures, may lead to fatigue phenomena due to induced continuous vibrations and consequently damages. Even if all the International Standards agree to define the velocity—expressed in terms of Peak Particle Velocity (PPV) or Peak Particle Component Velocity (PCPV)—as reference damage indicator, a standard procedure for calculating those values starting from accelerometers data is indeed absent (or needs to be better specified). This paper—taking into account that in most cases velocities cannot be directly measured—first compares the efficiency of two of the most common employed methods: the trapezoidal rule and the long Discrete Fourier Transform. This comparison is performed discussing the experimental activity performed on the SS. Annunziata's lodge in Florence (Italy) which is particularly exposed to traffic‐induced vibrations. Subsequently, a systematic analysis of the traffic‐induced vibration phenomenon was performed based on (i) dynamic identification by means of accelerometers data; (ii) calculation of the velocities (PPV and PCPV); (iii) analysis of the traffic component effects; and (iv) analysis of the Structure‐Soil Interaction (SSI) by using results obtained by means of Falling Weight Tests (FWT). Eventually, a comparison with the results of a previous dynamic test campaign performed in 1994 is reported, underlining a consistent increase of the traffic‐induced vibrations on the lodge possibly caused by the increase of the road unevenness.
