Based on 40+ Years of Leading Research

SIDRA INTERSECTION uses one of the most advanced methodologies of any road traffic analysis software.



Powerful SIDRA Model features allow for all intersection types: signals, roundabouts, sign control and pedestrian crossings in one network.

SIDRA complements the Highway Capacity Manual (HCM) as a lane-based intersection and network analysis tool. Unlike other software packages, the SIDRA HCM Setup does not claim to be a simple replication of the HCM procedures. Instead, it offers various extensions on the capabilities HCM offers.

Bus Blur

Diverse Movement Classes

Movement Classes can be allocated to different lanes, lane segments and signal phases, providing a unique method for modelling of Bus Priority Lanes, Bicycle Lanes, and so on.

Pedestrians Birds Eye


SIDRA INTERSECTION includes extensive treatment of signalised and unsignalised (zebra) pedestrian crossings at intersections and midblock locations.

Traffic Emissions

Environmental Analysis

Environmental assessment in traffic management, design, operations and planning can be conducted using models to estimate fuel consumption and pollutant emissions as a function of traffic conditions.
