“…In the case of the traffic light intersection Maior Şonţu a certain cyclicality is observed, this corresponds to the intermittent circulation that occurs on each band group [36,38]. For the flow on the East-South arm in the vicinity of which the noise measurements were made, there are traffic observations of interest [38]:…”

“…The LD 831 Digital Portable Sonometer (Figure 2) is a high-precision digital soundlevel meter, microprocessor-controlled, accuracy class 1 according to IEC 651 and IEC 804. The LD 831 sound level meter has the following technical characteristics [32][33][34][35][36][37] The meter is designed to measure sound levels in the civil and industrial sectors for statistical analysis, to verify compliance with noise pollution laws in urban and industrial areas, and to measure in difficult acoustic environments. The display shows the sound level in decibels, usually with a descriptor showing the selected time and frequency weight combination (e.g., LAeq or LApeak).…”

“…Although new vehicles models are becoming quieter, the increasing traffic volume of road traffic increases the noise emitted. Many of the city's central streets have reached traffic saturation, almost daily congested and with slower speeds throughout the day [18][19][20][21][22].…”

The paper addresses the problem of urban road noise, in the context of the European legislative requirements regarding noise pollution. The second noise mapping in Pitesti city, revealed that despite the proposed action plan after the first noise mapping, the noise pollution increased instead of decreasing. Considering that the proposed measures were insufficient to control road noise in the conditions of the estimated increase in road traffic, the authors developed complex research to identify how the road noise level is determined by the way of regulation of road traffic at intersections of the residential zone. Thus, noise and traffic measurements are made at the main road intersections in the central part of the city, determining the most relevant noise indicators for the specifics of urban traffic and residential areas. The results obtained lead to the conclusion that roundabouts bring a reduction in noise pollution compared to traffic light intersections only if the speed of vehicles in the roundabout is predictable: on preselected lanes and with speed timing.

“…VISSIM has chosen several authors as a means for its research into the optimal setting of traffic lights. While Maduranga focuses on strategy [20], Boroiu [21] points to the need to improve transport services by changing traffic light signalling plans. The authors of the study "Study on Performance of Intersection Around The Underpass Using Micro Simulation Program" also used VISSIM to create a micro-simulation model of the intersection [22].…”

Use of Universal Simulation Software Tools for Optimization of Signal Plans at Urban Intersections

Intersections in cities are important transport hubs, where traffic flows from all roads meet, connect, disconnect or intersect. This research is dedicated to the creation of simulation models of intersections and is based on real observations of two crossroads in a city. The principle is based on observing traffic flows using real traffic counting at peak times. The aim is to reduce traffic congestion by adjusting signal plans on the monitored section using computer simulation and modelling in ExtendSim8 software, which is a universal tool allowing the user to simulate any system or process by creating a logical representation in an easy-to-use format. According to our preliminary literature research, the ExtendSim software has never before been used before to create an intersection simulation to optimize the signal plan. There are several specialized software products for simulating traffic and intersections, but not everyone has access to these, or else they require lengthy user training. Therefore, it is very advantageous to use a universal simulation tool that is not used for traffic simulation at intersections in the city. The article points out that a universal simulation program such as ExtendSim can also be used in the design or assessment of signal plans at intersections.

“…Regarding the spatial efficiency of these two types of intersections, it should be noted that the differences are not major for the same number of lanes on the access roads, instead, calculating the spatial efficiency by relating the capacity of the intersection to the area required for development, specialized literature [4,5,6], as well as the results of the research carried out by the group of authors [7], reveal that spatial efficiency decreases with the increase of the number of lanes on the circular path.…”

One of the major road traffic problems in Pitesti is manifested in the roundabout at Podul Viilor, which, although occupying a fairly generous space, has a very low level of service during peak hours, due to difficult access from one of the arms. The research, based on traffic measurements performed with DataFromSky software and micro-simulation traffic analyses performed with Vissim PTV software, indicated as the only solution the redirection of road flows from the intersection, which required traffic analysis for a larger area. The results obtained for the proposed scenarios - by estimating the degree of road congestion not only in the respective intersection, but also in the adjacent intersections, through which some road flows are reoriented - indicate that in this way a substantial improvement of the road traffic can be obtained for the intersection of Podul Viilor, without significantly affecting the traffic in the adjacent area. Thus, it is found that the service level of an intersection can be increased not necessarily through new road arrangements, but only through better regulation of road traffic in the area, based on the analysis of various scenarios using measurement software and traffic modelling.
