Traffic safety situation in Lithuania, despite the progress made in 2008, is still not good enough compared to the other European Union countries. Therefore, Lithuania implements the traffic safety improvement measures affecting all the elements of the traffic safety system “Road user‐road‐vehicle”. In 2008 Lithuania started implementing the road safety audit procedure which substantially contributes to the improvement of safety situation on Lithuanian roads. This article gives the analysis of road safety audits of special plans and technical designs for road construction and reconstruction in Lithuania, makes the analysis of the main deficiencies of plans and designs and gives recommendations for their elimination. Santrauka Eismo saugumo situacija Lietuvoje, nepaisant 2008 m. pasiektos pažangos, vis dar yra nepakankamai gera, palyginti su kitomis Europos Sąjungos šalimis. Atsižvelgiant į tai, Lietuvoje įgyvendinamos eismo saugumo gerinimo priemonės, darančios įtaką visiems eismo saugumo sistemos „Eismo dalyvis–kelias–transporto priemonė“ elementams. Lietuvoje 2008 m. buvo pradėta taikyti kelių saugumo audito procedūra, kuri prisideda prie eismo saugumo gerinimo Lietuvos automobilių keliuose. Straipsnyje pateikta Lietuvoje atliktų specialiųjų planų ir automobilių kelių tiesimo bei rekonstrukcijos techninių projektų kelių saugumo auditų analizė, išanalizuoti pagrindiniai planų ir projektų trūkumai, pateiktos rekomendacijos jiems šalinti.

Analysis of Factors Influencing the Density of Fatalities on National Roads in PolandIn Poland 20% of the total number of accidents occur on the national roads, which constitute 7% of the length of all roads. In the case of fatalities this share is significantly higher as it constitutes up to 36% of the total casualties. In accordance with the EU Directive (Journal of Laws EU L. 319/59) the level of road traffic safety should be raised by targeting investment on the most dangerous road sections. Finding the dependence between road and traffic factors and the number of accidents and casualties of road accidents may be helpful in predicting safety levels and selecting road traffic safety improvement measures. The paper presents the experience of other countries and preliminary tests results of the impact of the selected factors on the density and the number of road accident fatalities on the national roads in Poland.

As an important node of the urban transport network, road signalized intersection collects more than one direction of traffic flows. Thus, it not only becomes the throat of the transportation network, but also accident-prone area. Through field survey, this paper analyses a typical signalized intersection with safety problems and proposes an improvement design plan. Afterwards, with the use of the crash reduction factor (CRF), it forecasts the effects of safety improvement measures.

This study developed an evaluation model of freeway traffic safety facilities system. Firstly, an evaluation system of freeway traffic safety facility was proposed. Secondly, an evaluation model was proposed based on attribute recognition theory. And the evaluation result was identified according to the attribute measure value of single index and the comprehensive attribute measure value of multiple indexes as well as the confidence criterion. Thirdly, the weight of each indicator was decided by variation coefficient. Finally, A case of TAI-GAN freeway (K1+242~K3+259 segment) was conducted to verify the feasibility and effectiveness of the model.

Maintaining the high visual recognizability of traffic signs for traffic safety is a key matter for road network management. Mobile Laser Scanning (MLS) systems provide efficient way of 3D measurement over large-scale traffic environment. This paper presents a quantitative visual recognizability evaluation method for traffic signs in large-scale traffic environment based on traffic recognition theory and MLS 3D point clouds. We first propose the Visibility Evaluation Model (VEM) to quantitatively describe the visibility of traffic sign from any given viewpoint, then we proposed the concept of visual recognizability field and Traffic Sign Visual Recognizability Evaluation Model (TSVREM) to measure the visual recognizability of a traffic sign. Finally, we present an automatic TSVREM calculation algorithm for MLS 3D point clouds. Experimental results on real MLS 3D point clouds show that the proposed method is feasible and efficient.
