摘要：The paper presents the evaluation of effectiveness of non-standard road marking and signs (ES) in speed management. Transverse strips, speed limit signs dedicated to selected lanes, non-standard sign, which inform about slippery pavement at motorway curve during the rain. were analysed. Based on survey, degree of understanding of the content of analysed marking and signs by road users was assessed. Empirical studies allowed for evaluation of change in speed caused by non-standard marking and signs implementation. Results show that non-standard marking and signs can be effective speed management measures. The paper also point out problems in evaluation of ES implementation.
