Tier 1 Analysis Tools

DOTD Approved Traffic Software

    • HCS
    • Sidra
    • Vissim - Only tool allowed for microsimulation 

 

LADOTD uses the HCM (Highway Capacity Manual 6th Edition) for traffic analysis methods and equations.  HCS (Highway Capacity Software) will only be allowed for the equations that are in the HCM and cannot be tweaked to provide output for solutions that are not in the HCM.  For conditions, limitations or other scenarios that cannot be addressed with HCS, approval shall be obtained before utilizing other software.  Using travel time as an MOE and oversaturation are two examples that need approval to use macroscopic or mesoscopic software.  For questions or concerns, please contact the Traffic Engineering Division Administrator at 225-379-1232.
