SIDRA-2 does it Lane by Lane

SIDRA-2 implements the techniques described in the ARRB Research Report ARR No. 123 (Traffic Signals: Capacity and Timing Analysis). Although the fundamental principles and methods are the same, there are some important differences between ARR No. 123 and SIDRA-2. The most important is the lane-by-lane calculation of capacities and operating characteristics such as delay, number of stops and queue length. Lane-by-lane calculations allow for the use of different lost times, hence different effective green and red times, for different lanes, which improve the results for operating characteristics.
