Description

The thesis examines the problem of selecting locations for bypasses and fast speed streets in urban areas. The work is focussed on the impact of the bypass and fast speed street locations on traffic flows in a street network. A methodology for selecting such locations has been developed by means of a traffic flow modelling that does not require a complicated modelling exercise that includes all traffic flows in a city and can be time consuming and costly. The methodology has been adapted to two biggest Lithuanian cities: Vilnius and Kaunas. The purpose of the work is to design the methodology for selecting locations for bypasses and fast speed streets by means of traffic flow modelling and to put it into practice with the aim to shorten travel times for residents of the city.

The thesis consists of the introduction, three chapters, the general conclusions, the list of references, the list of author‘s publications on the topic of the dissertation, summary in English and eleven annexes.

The introduction contains a brief discussion of the problem under investigation and relevance of the work, a description of the object of investigation, a statement of the objective and tasks of the thesis, a description of scientific novelty of the work, and the statements being defended. The author’s publications and reports delivered at conferences as well as the structure of the thesis are presented at the end of the introduction.

In Chapter 1, an overview of the literature on the subject is presented and relevant research works as well as national and European Union’s documents on transport policies are analysed.

A transport model developed for an ideal city is presented in Chapter 2. 90 variants for locations of bypasses and (or) fast speed streets were modelled. The methodology for selecting locations for bypasses and fast speed streets has been developed upon analysis and summarisation of the modelling results.

Chapter 3 deals with the main transport research methods that are affordable, can be employed at minimal cost and can ensure sufficient coverage and accuracy. Based on an analysis of the two biggest Lithuanian cities, – Vilnius’ and Kaunas’ transport systems, their main parameters have been determined and the methodology for selecting locations for bypasses and fast speed streets has been applied to them.

Out of five scientific publications on the subject of the thesis, four are in the journals referred to by Clarivate Analytics (ISI Web of Science). Results of the research have been reported at two conferences held in Lithuania and one conference abroad.
