Left Turn Lanes at Signalized Intersections
|

I read FHWA-HRT-04-091 on Signalized intersections. Page 308, Chapter 12 references the HCM 2000 in stating the probable need for a left turn lane if the volume is greater than 100 vehicles in the peak hour. Does anyone know if this information was updated in the HCM 2010, & if so, where in the HCM 2010 I can find it? |

That information appeared on pages 10-17 and 10-18 of HCM 2000. As far as I know, similar information does not appear in the HCM 2010. Page 18-74 suggests following (in order) local guidelines, local practice, or national guidance if an input value to the signalized intersection method is not known. |
