Sub-problem 2a: Analysis of the
Existing TWSC Intersection Considering the Effects of the Adjacent Intersections
Step 2. Results
The HCM procedure produces the following results for each minor stream movement:
 |
capacity of the movement and
the capacity of the lane or lanes |
|
delay for the movement and the
weighted average delay for each lane |
|
95th-percentile queue for each lane |
| level of service for each lane |
These results are summarized in Exhibit 1-20, for the
existing volumes.
