Abstract—this paper presents a newly developed micro-simulation model for shuttle-lane urban roadworks (which is closing one lane of a single carriageway road while leaving the other for use by both directions in an alternate one-way working) focusing on issues relating to Temporary Traffic Signals (TTS) control and its effectiveness. The model deals with general as well as more specific drivers' behavior, such as following too closely (tailgating), effect of dilemma zone and non-compliance with temporary traffic signals. The main criteria of this model are governed by the application of car following and shuttle-lane rules. The model has been calibrated and validated using real traffic data taken from observed urban shuttle-lane roadworks sites for both Fixed Time (FT) and Vehicle Actuated (VA) TTS. Modified signal settings and various MVD (Microwave Vehicle Detector) detection ranges were also assessed in terms of their impact on capacity (throughput) and delays.
