    Abstract
    Pedestrian signal control is a main influencing factor on the Level of Service of crossing facilities and on the safety performance considering conflicts with vehicles. In signal design, pedestrian clearance time is a key design parameter for ensuring safe pedestrian crossing at signalized crosswalks. The performance of pedestrian signal control and its impact on pedestrian behavior in the Gulf Cooperation Council (GCC) Countries is rarely addressed in the literature. The characteristics of population, cultural diversity, as well as the extreme hot weather conditions, may lead to significantly different pedestrian behavior in terms of crossing manoeuvres (path and speed), compliance with signal control and interaction with vehicular traffic. This study reviews the pedestrian signal design practices in various countries and investigates the current signal settings along with their adequacy in the State of Qatar using empirical observations. The empirical analysis showed that the 85th percentile crossing times were longer than the provided Pedestrian Flashing Green (PFG) intervals at the observed crosswalks. Study sites are characterized with unrealistically long Buffer Intervals (BIs) which, from one side, provide sufficient time for pedestrians who started crossing during PFG to complete the crossing. On the other side, they encourage pedestrians to continue crossing after the end of PFG. Additionally, the speed analysis indicated that the observed 15th percentile speed was 1.22 m/s which is similar to the assumed design speed by the Qatar Traffic Control Manual QTCM (2015). Further, the analysis showed that pedestrian crossing speed during PFG or BI was significantly higher than that during PG.
