Sidra-2 user guide
Sidra-2 is a computer program to aid traffic engineers and researchers in the design and analysis of signalised intersections. It is based on the analytical techniques described in the ARRB research report arr no 123 (traffic signals: capacity and timing analysis). Further improved techniques have been employed in sidra-2. In particular, the capacity and performance calculations are carried out on a lane by lane basis. Sidra-2 includes advanced techniques to solve the problems of opposed turns, short lanes and interaction of different movements in common lanes. It also includes improved models of operating characteristics (delay, number of stops and queue length) and fuel consumption. Basically, sidra-2 uses analytical models of traffic and iterative approximation methods of computation. It is highly efficient in computer time usage. This report provides a technical guide for sidra-2 users. Sidra-2 input data are supplied on several card types which are explained in detail. Input data errors and sidra-2 output information are also explained. Complete examples of sidra-2 input and output are given. Sidra-2 output includes listing of basic movement and intersection variables, estimates of lane and movement flows, saturation flows and capacities, computed signal timings, a signal timing diagram, and performance measures for computed or specified signal timings with separate printouts for individual lanes and movements as well as summation for movement groupings specified by the user (a).
