A Microcomputer Package for Interrelating the Highway Capacity Manual and SOAP 84
There is some evidence that the SOAP program may replicate signalized intersection delay more realistically than the 1985 Highway Capacity Manual (HCM) operational procedure for signalized...
A Practical Way of Using the 1985 HCM - Signalized Intersection Methods
The signalized intersection chapter of the 1985 Highway Capacity Manual (HCM) is probably the most widely used chapter, and thereby the most significant, and yet is very complex and sometimes...
