IP0024 - A Study on the New Design Standards for Weaving Section in terms of Traffic Safety and Operation
This research deals with methods to develop new design standards of the weaving section to improve traffic safety and efficiency, and considers the status quo and problems of the weaving section. This research sought to establish design criteria to prevent problems in advance that can occur in the weaving section such as vehicle conflict and traffic accident. The final goal of the research is to [...]

IP0090 - An Analysis On The Effect Of Geometric Elements On Traffic Accidents At Curves
Abstract Traffic accidents have serious public health and economic concerns all over the world, especially developing countries. This research study focused on the analysis of traffic accidents related to radius and superelevation of the existing asphalt road. The primary data mainly covered the geometry of the road which were collected during the accident forensic investigation for a 6 years period [...]

IP0323 - Application of a Mexican predictive velocity model for the evaluation of horizontal alignment consistency
The evaluation of consistency by speed in the horizontal alignment allows the uniformity of the successive segments of a road considering the driver's expectations. This evaluation makes it possible to relate the geometric aspects of a road to some variables related to the human factor such as: desired speed, perception of the alignments, driver's mental workload, road logic, among others. This evaluation [...]

IP0647 - Digitalization in Infrastructure Sector as a Path to Efficiency
State Found for Transportation Infrastructure have started to implement digitalization in 2017. This paper summarizes achieved results in cooperation with Czech Road and Motorway Directorate, Railway Administration and Waterways Directorate since then. Paper describes principles applied on Czech national level through national standardization and methodologies and its relations and common principles [...]

IP0119 - Effectiveness of BIM and Driving Simulations to Identify Safety Issues in the New Road Design Process: A Case Study of the Kretek-Girijati Road, Yogyakarta, Indonesia
A road should be designed with consideration of road physical elements, vehicle design and human factors. Regardless of the road standard applied and the safety assessment of the new road design, a number of safety issues remain exist at the operation phase. Previous research demonstrated that preventive measures have been shown to be effective on minimising safety risks. However, in practice of new [...]

IP0285 - Implementation of BIM/CIM to Road Design for a Japanese Highway Project, Kobe-Nishi Bypass
Building/Construction Information Modeling/Management (BIM/CIM) is the key process to enhance the productivity of all processes of civil infrastructure projects such as plan, investigation, survey, design, construction, operation and maintenance (O&M), and rehabilitation. This paper presents efforts for introducing BJIM/CIM to the Daini-Shinmei Road from Nagaidani Junction (JCT) to Ishigadani JCT [...]

IP0710 - Modern Ways of Design of Two-Lane Roads in Rural and Urban Areas
Rural two-way roads with middle dividing strip or double solid white line in the middle in order to prevent dangerous car overtaking on two-lane roads, which are equipped with short passing bays along the outer edges of both road lanes in regular distances. The aim of these passing bays is the safer replacement how to realize overtaking of another slower car instead of common overtaking on non-divided, [...]

IP0532 - Non-Signalized Crosswalks Design Influence on Children Pedestrian Behavior
Traffic safety of children in urban environments has been analyzed because of different reasons – the main is that traffic accidents are the leading cause of death among young children and that their cognitive capacities, up to certain age, do affect significantly their traffic behavior. Getting children independent in traffic at a younger age has a positive effect on their health and development [...]

IP0790 - Review of visibility guidelines in France: Update of the related fundamental parameters and introduction of a performance-based approach to optimize the design of road projects
Visibility is a key factor for the safety level of a road. It leads to a set of rules and conditions that determine the design of road infrastructures. In some cases, these rules can be significant and lead to an increase in the cost of road projects or their impacts on the territory. These requirements and their foundations were established decades ago and the deterministic approach on which [...]

IP0728 - The utopia of BIM without considering project management
The BIM methodology is developed without considering the ICE sessions, prior to the design stage (Detailed Engineering), which are aimed at multidisciplinary coordination, with the purpose of knowing and identifying the existing conditions of the work area through a BIM coordination model, thus allowing the optimization of decision making for an efficient development of the design. By not considering [...]
