sidra intersection provides a large number of intersection and network performance measures and a number of alternative level of service (los) methods and los target settings to determine acceptable intersection and network design. standard performance measures such as delay, queue length and number of stops as well as measures to help with environmental impacts and economic analysis are provided. performance and level of service results are given at various aggregation levels (individual lanes, individual movements, approaches, intersections, routes and networks) and separately for vehicles, pedestrians, and persons (results for pedestrians and people in vehicles combined). extensive graphical displays present signal timing and performance output.
