Recently, new traffic data sources have emerged raising new challenges and opportunities when applying novel methodologies. The purpose of this research is to analyse car travel time data collected from smartphones by Google Company. Geographic information system (GIS) tools and Python programming language were employed in this study to establish the initial framework as well as to automatically extract, analyse, and visualize data. The analysis resulted in the calculation of travel time fluctuation during the day, calculation of travel time variability and estimation of origin-destination (OD) skim matrices. Furthermore, we accomplished the accessibility analysis and provided recommendations for further research.

Globally, fire causes considerable losses that can be alleviated by taking appropriate actions facilitated by systems supported by geo-information technologies. This research focuses upon the development of an approach for planning urban infrastructures, and particularly in the accessibility of fire hydrants. Accessibility of fire hydrants’ infrastructure in urban territories is one of the key elements in fire risk management and public safety. The main result of the research is a comprehensive and structured Geographic Information Systems (GISs)-based dataset for the fast and more efficient planning of fire hydrants in urban territories. The proposed framework for data collection and processing was used to determine the distribution of hydrants, location of fire brigade stations and areas and to demonstrate the capabilities of the existing municipal fire extinguishing systems in Vilnius City, Lithuania. Later on, research on fire hydrants’ accessibility, analysis of the location of protected and unprotected urban territories and marking of unprotected buildings, was carried out. The resulting map of unprotected urban territories can be of great benefit for understanding fire risks and offering more effective ways for fire risk management.

This work aims to identify the effectiveness of one-level signalized intersections with exclusive pedestrian phases in terms of vehicle-pedestrian crashes resulting in pedestrian injury or fatality. The work analyzes and evaluates specific exclusive pedestrian phases without diagonal crossing possibility at one-level signalized intersections in the city of Vilnius. Anonymized data on traffic accidents from the Lithuanian Police Department Accident Register were used for safety analysis purposes. The traffic accident data cover all traffic accidents with dead or injured persons. The traffic accident data was analyzed with the help of QGIS for selected time intervals (before and after analysis). The density of traffic accidents was calculated with the help of the comparative analysis method at 11 signalized intersections in Vilnius City, where an exclusive pedestrian phase without diagonal crossing was implemented. An exclusive pedestrian phase with diagonal crossing is usually implemented to increase pedestrian safety at a signalized intersection with a high pedestrian intensity. The analysis carried out indicates that the specific exclusive pedestrian phase without diagonal crossings in Vilnius reduced pedestrian traffic accidents by up to 100%. No traffic accidents occurred after the installation of the exclusive pedestrian phase at intersections where there were no pedestrian accidents prior to the installation.

A rapid growth in car ownership in the cities of Lithuania, particularly in Vilnius, has generated continuous traffic jams in the streets and thus has consequently increased negative transport impact and demand for financial and land resources. Also, a high level of car ownership requires large reserves of transport infrastructure. Therefore, it is necessary to create favourable conditions for creating sustainable urban transport infrastructure satisfying the needs of local inhabitants. Within the framework of the European Union Structural Assistance for the period 2014-2020, Vilnius city municipality administration is planning to submit an application to receive financial support for the implementation of the Park-and-Ride (hereinafter P&R) scheme for Vilnius. The aim of the paper is to work out a multi-criteria methodology for selecting the sites of P&R lots and to carry out a developmental analysis of P&R facilities by creating the above introduced scheme for parking lots in the Vilnius City. The expert method has been used for utilizing a set of relevant criteria for planning the P&R scheme. With the help of the expertsurvey, the weights and significance of the defined criteria have been identified. Multi-criteria methods have been applied for calculating and presenting the developmental priorities and a strategy for the implementation of the offered proposals.

The Directive 2008/96/EC of European Parliament and of the Council requires the establishment and implementation of procedures relating to road safety impact assessments, road safety audits, the management of road network safety and safety inspections by the Member States. Directive aims to develop procedures with the aim of increasing safety of road infrastructures. Road Safety Impact Assessment (RSIA) is an initial part of road infrastructure safety management systems. This article describes the scope of RSIA procedures, provides detailed recommendations on qualification of auditors, implementation and execution of procedures for the EU Member States. Road safety should play an important role when routes are being selected and safety awareness should be included in the decision making during the designing/planning stage. RSIA is a very beneficial tool that could increase transparency and availability of information, consequently, it leads all parties concerned to well-informed decisions.
