Analysis of the Traffic Parameters on a Section in the City of the National Road during Several Years of Operation

Abstract

The study carried out an analysis of the vehicle traffic parameters on a national road in 2011-2016. The variability and uncertainty of results were evaluated. An analysis of traffic data recorded on the city's entry and exit lanes was carried out. The variations in traffic volume are of interest e.g. in dynamic traffic management systems and navigation services, examining the benefits of flexible work time and places and assessing the environmental effects of traffic congestion. Research has shown that the assumption that lanes perform equally is not always true. Traffic volume models should be periodically calibrated taking into account the shape of the daily profile, which may, for example, allow public transport timetables to be more responsive to the needs of travelers.

Analysis of Urban Traffic Noise at Weekends – Case Study

“…The traffic volumes and noise analyzed in this study were measured [12] by the permanent station recording traffic volume, velocity, and sound pressure levels located in Popieluszka Av. in Kielce.…”

“…Compared to Saturdays on Sundays, both the shape of the speed chart and the speed values at individual hours of the day are different. The analysis of the share of individual groups of vehicles in the traffic structure [12] showed that the dominant group is passenger vehicles, for which the share in the traffic flow was on Sundays 84%. The next group was medium-heavy vehicles, for which the share in the analyzed period amounted on Sundays to 11%.…”

“…For this reason, in the further part of the work, the traffic of passenger vehicles will be analyzed. Figure 2 presents traffic volume box plots for individual hours of the day for passenger vehicles on weekends [12]. On Saturdays (Fig.…”

“…day, evening, and night, is justified for physiological and normative reasons related to the harmful influence of transport on humans. On the other hand, it is complicated by the mathematical description of the variability of the values of vehicle motion parameters as a function of time, which was presented in [12].…”

“…An additional factor influencing the acoustic climate is the modifications to the road infrastructure, the aim of which may also be to reduce the emission of traffic noise to the environment [11]. That is while it is necessary to permanently monitor over a long period of time vehicle traffic and analyze the recorded data [12]. The variations in traffic volume and noise are of interest e.g.…”
