“…The modelled vehicles were also used in terms of simulation of the passage of the vehicle [35] at a selected intersection in an urban area. The simulation served as another To complete the values, the minimum and maximum values of deviations for the individual edges of the semi-trailer and the edges of the tractor are given.…”

“…These include the determination of backbone routes within the Czech Republic, the creation of software models of vehicles for the verification of swept paths and the determination of geometric parameters for the design of a communication network. The suggested solution must not influence the other participants in the traffic from the perspective of their safety [34][35][36][37][38].…”

The article deals with the transport of oversized cargoes from the perspective of parameters of road network in city environments. In recent years, there has been an increase in the transport of products with dimensions and weight considered above standard. It is very difficult to transport these products not only within Europe but also worldwide. This is also pointed out in the European directive, which recommends that all EU member states build a pan-European network of corridors for the transport of oversized cargoes. The article analyses the issue of transport within the transport infrastructure in cities from the perspective of sustainability of road networks for ensuring the passage of oversized cargoes. The article describes the results of research that was performed for the determination of parameters to ensure the passage of oversized cargoes on roads. The article also deals with the analysis of implemented transports, the results of video analysis of monitored transports, measurement of swept paths of vehicles using GPS apparatus and drones, modelling of oversized vehicles in programs for verification of the swept paths of vehicles, simulation of passage of oversized cargo, the determination of values of radii of corners, widths and heights for the transport of cargoes and the distance from solid obstacles. The precondition for the above-mentioned outputs is the practical use of results in planning the transport infrastructure on the entire communication network and the possibility of its application for designing activities associated with the construction or reconstruction of intersections on routes of frequent transport of excessive and oversized cargoes and verification of critical points on the route. The outputs of the work serve as a basis for the processing of technical conditions, which include procedures and technical recommendations within the design practice in the Czech Republic but also abroad. Emphasis is placed on sustainable, safe and economic transport infrastructure.

“…The analysis and evaluation of the given hypotheses of the research also involved computational procedures from Czech standards and regulations [33,51,52] and foreign standards and regulations [37,38,44,[53][54][55], technical conditions [2], methodologies [30] for designing of turbo roundabouts, and calculations for turbo roundabout capacity [56][57][58][59][60][61]. For the evaluation, our own procedures were designed, where simulations of the passage of a vehicle through a turbo roundabout, the probability of analysis in terms of the use of lanes, the passage of the vehicle through physical separation elements, etc.…”

“…These bases must coexist so that they do not negatively influence each other, and thus form a comprehensive, functioning, and long-term sustainable system. An example related to the focus of this study is the design of intersections (roundabouts); if the dimensions or geometric layout of an intersection are such that motor vehicles have difficulty passing through the intersection safely, dangerous situations may occur (i.e., traffic conflicts [1][2][3][4][5] or even accidents [6,7]). For example, an intersection with a small corner radius can be a problem, if it forces a driver who is turning right to enter the opposite direction when exiting the intersection.…”

The designs of turbo roundabouts vary among countries and undesirable and potentially dangerous situations can occur for vehicles passing through the roundabout. In this article, we focus on an analysis of one of the problems within sustainable road transportation, i.e., the geometric layout of turbo roundabouts. First, we review the Czech and foreign regulations and describe the design procedures for turbo roundabouts. Studies that have been performed in the Czech Republic and abroad (the Netherlands, Slovenia, Poland, Germany, Hungary, etc.) are described. We evaluate the geometric layout of turbo roundabouts, the effectiveness of construction adjustments at the entrance to the roundabout, and an analysis of the physical separation of lanes. We present procedures and methods for measurements and assessments, which are used for evaluating the effectiveness of the geometry of a turbo roundabout. Finally, conclusions for the given hypotheses are given, as well as the importance of geometric elements (shape of the turbo roundabout, physical separation of lanes, the spike, etc.) for the actual passage of vehicles through the turbo roundabout. Furthermore, we discuss how these elements influence the safety of road traffic, the sustainability of road transportation, and the emergence of potentially dangerous situations.

“…In road network, pedestrian safety is commonly analyzed in terms of the number of crashes between pedestrian and vehicle (Kocourek, Padělek 2016;Roshandeh et al 2016). However, this approach failed to quantify actual safety conditions for pedestrians due to unavailability of accident data and exposure measures.…”

The large proportions of pedestrian fatalities led researchers to make the improvements of pedestrian safety at intersections. Thus, this paper proposes a methodology to evaluate crosswalk safety at signalized intersections using Surrogate Safety Measures (SSM) under mixed traffic conditions. The required pedestrian, traffic, and geometric data were extracted based on the videographic survey conducted at signalized intersections in Mumbai (India). Post Encroachment Time (PET) for each pedestrian were segregated into three categories for estimating pedestrian-vehicle interactions and Cumulative Frequency Distribution (CDF) was plotted to calculate the threshold values for each interaction severity level. The Cumulative Logistic Regression (CLR) model was developed to predict the pedestrian mean PET values in the crosswalk at signalized intersections. The proposed model was validated with a new signalized intersection and the results were shown that the proposed PET ranges and model appropriate for Indian mixed traffic conditions. To assess the suitability of model framework, model transferability was carried out with data collected at signalized intersection in Kolkata (India). Finally, this study can be helpful to rank the severity level of pedestrian safety in the crosswalk and improve the existing facilities at signalized intersections.
