    1. 

    You can use the TORUS Roundabout software to evaluate user drawn roundabout designs?

    2. 

    R1<R2<R3 is a condition prescribed in checking speed consistency in a roundabout based on NCHRP 672.

    3. 

    The design speed of the roundabout is defined by the smallest radius along the fastest allowable path.

    4. 

    TORUS is able to handle designs with 5 legs.

    5. 

    Why is speed consistency for roundabout design important for designers and engineers?

    6. 

    What is the maximum number of entry and exit lanes TORUS can currently support?

    7. 

    NCHRP Report 672 prescribes that the maximum speed differential between movements should be no more than approximately how many mph?

    8. 

    Which references did Hannah refer to for the fastest path construction methodology?

    9. 

    What is R4 in the fastest path methodology?

    10. 

    Which set of offsets (from splitter island, central island, and corners) are used in construction of the through fastest path?
