“…The acquired records were also processed using digital image analysis [20,33,[39][40][41]. Furthermore, measurements using GPS technology were used [11] and software models of vehicles were created to determine (verify) the parameters similarly as in [42], which would ensure the passage of transports on roads (the issue is described in more details in the following publications [11,12,33]).…”

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 final size of the inscribed circle is determined based on the design parameters (Robinson et al 2000). According to Godavarthy et al (2016), the radius of the inscribed circle is mostly affected by the turning path required for the design vehicle for single-lane roundabouts. Table 2.2 shows common design vehicles considered for roundabouts and their corresponding required inscribed circle diameter.…”

The existing Stopping Sight Distance (SSD) and Decision Sight Distance (DSD) design methods for roundabouts are deterministic. This means that all of the design variables are predetermined, fixed values. This study presents a probabilistic method for the determination of SSD and DSD at roundabouts based on the equation recommended by the American Association of State Highway and Transportation Officials (AASHTO 2011). The reliability-based method considers all design parameters as random variables. Three types of SSD (SSD for approaches, SSD along the circulatory lane, and SSD for exiting vehicles to the pedestrian crosswalk) were considered in this study. DSD was considered for roundabout approaches. The First-Order Second-Moment and Advanced First-Order Second-Moment methods were used to model SSD and DSD. Once the required SSD and DSD were determined, the lateral clearance requirements at every point of the roundabout were calculated.

“…A comprehensive list of roundabout features to facilitate all the above mentioned oversized truck accommodation strategies are: wider and custom center island truck aprons, need for external truck apron, traversable splitter islands, fully traversable center island, removable signs in a roundabout, and no poles in the swept path area of oversized truck/trucks expected [10] [11] [12] [13]. …”

Roundabouts in United States and other countries have been proved to be very successful, effective, and a safe traffic control treatment. Roundabouts in the context of regularly expected truck configuration have also been successful for effective roundabout designs; however, there are always some site specific issues for trucks accommodation at roundabouts. Therefore, there is a great need for an informational guide in the form of synthesis report for roundabout designs specific to unique trucking traffic activity. While there are not significant literatures and studies in this subject, there are few studies/reports spread out which address various issues in this subject area. This study attempts to synthesize the research and knowledge of truck accommodation at roundabouts by synthesizing various research studies, reports, and articles; various subject areas such as roundabout designs for trucking activity, roundabout designs and accommodation strategies for specialized trucking activity such as oversized trucks, truck safety at roundabouts, and motor carrier perspective of trucking at roundabouts have been analyzed and relevant knowledge has been synthesized. This synthesis can be useful o researchers, designers, planners, and decision makers to determine effective ways to address specific trucking related issues at a roundabout.
