The formulation of scenarios for developing the urban transport infrastructure requires decisions mainly based on the intuition of experts in transport and highly influenced by public interest groups, business entities and political opinions. However, the reached decisions sometimes fail to be the most efficient. Therefore, to avoid errors and ensure the development of a sustainable transport system, the economical appraisal of infrastructure development scenarios is necessary. The economic evaluation of the developed scenarios can be carried out through macro-simulation and cost-benefit analysis. This paper deals with the Kaunas City Master Plan providing solutions to transport infrastructure development. According to the Master Plan, solutions can be classified considering 3 cathegories (priorities), although the detailed sequence of implementation is not given. With the help of macro-simulation, this study arranged Master Plan solutions into scenarios, checked all 20 scenarious and established an implementation order based on the theory of cost benefit analysis. The identified order substantially differs from the priorities set in the Master Plan.

A rapid rise in car ownership in the cities of Lithuania, particularly in Vilnius, has generated continuous traffic jams in the streets and thus has consequently increased a 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 receiving financial support for the implementation of the Park-and-Ride (hereinafter P&R) scheme for Vilnius. The paper is aimed at working out a multi-criteria methodology for selecting the sites of P&R lots and at carrying out a developmental analysis of P&R facilities by creating the above introduced scheme for parking lots in 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 expert survey, the weights and significance of the defined criteria have been identified. Multi-criteria methods have been applied for calculating and presenting 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.

Directive 2008/96/EC on road infrastructure safety management requires the establishment and implementation of procedures relating to road safety impact assessments (RSIA), road safety audits (RSA), ranking of high accident concentration sections and network safety ranking (NSR) and road safety inspections (RSI). The aim of this article is to present the outputs of BALTRIS project. The goal of the international project BALTRIS is to elaborate the road and street infrastructure safety management procedures and teaching material consistently explaining the above mentioned infrastructure management procedures. Four Baltic Sea region countries (Sweden, Estonia, Latvia, and Lithuania), represented by universities and national road administrations participate in the elaboration of these procedures and teaching material. This article describes the scope of NSR, RSA and RSI procedures prepared in the frame of BALTRIS project, also article provides detailed implementation and execution of procedures for the EU Member States. NSR means a method for identifying, analysing and classifying parts of the existing road network according to their potential for safety development and accident cost savings.Ranking of high accident concentration sectionsmeans a method to identify, analyse and rank sections of the road network which have been in operation for 3÷5 years and upon which a large number of fatal/injury accidents in proportion to the traffic flow or compared to respective conditions have occurred. RSI is a strategic comparative analysis of the impact of the new road or a substantial modification to the existing network on the safety performance of the road network. RSA is a formal safety performance examination of the existing or future road or intersection by an independent audit team. First Published Online: 21 Dec 2012
