Traffic Engineering Analysis in the Preparation and Reconstruction of Urban Roads

Abstract

The contribution deals with issues of road administration in municipalities in terms of the requirements for engineering renovations of urban communications networks. The goal is to declare an end to the degradation of the quality and service of local roads in cities. The reason is the lack of funding. The engineering analysis should demonstrate the need to make an informed request for reconstruction of local roads in our towns and cities. The aim of this paper is to describe the processes that are related to specific engineering work but are closely linked to the performance of the preparation on both sides, i.e., the administration versus the design. Why do we passively observe the gradual destruction of the quality of our local roads in the cities? Before our eyes the road constructions of roadways crumble, on the other hand, the level of their transport service on them only presents us with traffic jams. How can you know the status of the background of our streets and their pavements in an urbanized area? A couple of technical studies oriented towards the advance of public transport, especially for Bratislava, the capital of Slovakia which were based on traffic modelling together with engineering designs were published (Borš et.al, 2017; Pomichal et.al, 2017; Koštial et.al, 2017; Schlosser and Schlosser, 2016; Schlosser and Orthová, 2016; Schlosser et.al, 2016; Schlosser et.al, 2017; Schlosser et.al, 2017). Some answers to the complexities of this issue are set out in this article.

Safety Assessment of Adjacent Roads Sections via Maximum Entropy Driver's Perception Field

“…where: X (1) , X (2) -the actual distances from the vehicle to the edge of the roadway in the cross section of the road in the first and second sections, respectively; V (1) , V (2) -the actual vehicle speeds in the first and second sections, respectively; , X X…”

“…At the present stage of development of transport engineering, the system arrangement of the road environment is the main means of ensuring the traffic safety. Approaches to reducing accidents, due to technical means of organizing the traffic, have practically exhausted themselves [1]. At the same time, existing approaches can be improved and supplemented, taking into consideration the human factor in assessing their safety [2].…”

“…In [1] the condition of the roadway is taken as a characteristics that affects the accident rate. A systematic approach was used, consisting in study of relationship of the four elements: driver's behavior, vehicle conditions, roadway bed and environment.…”

Transit Smart Solution for Bratislava – Example of Tramway Network Development

“…As has been said above of the dynamic transport is published in sufficient details in [5 and 32]. A rich discussion is underway around the world, and the decision-making process for this project was made of all the relevant documents that are presented and referred to the various studies and researches published in [24] and [27]. From them, for the Slovak conditions we rather looking for European solutions, which are also in certain specifics adopted for the transport model in Bratislava.…”

Reducing Delay Time at Signal Controlled Junction with the Help of Actuated Control

“…This kind of problem is described e.g. in [16]. At present, Martin intends to build traffic lights at this junction.…”
