In this Received in revised form 28 February 2013 paper, we aim to build appropriate distribution models for start-up lost time and effective Accepted 12 March 2013 departure flow rate, by considering their relations with the frequently mentioned depar- ture headway distributions. The motivation behind is that distribution models could pro- vide richer information than the conventional mean value models and thus better serve Keywords: the need of traffic simulation and signal timing planning. To reach this goal, we first check Departure headway empirical data collected in Beijing, China. Tests show that the departure headways at each Start-up lost time Departure flow rate
