The proposal for the NCHRP 3-55(3) project "Capacity and Quality of Service of Two-Lane Highways" was submitted in May 1995 and the contract was awarded to MRI in the early fall of 1995. A working plan was submitted in October 1995 and work on the project began immediately.
The project was divided into eight major tasks with the first four tasks being designated as Phase I and the last four tasks being designated as Phase II. The eight major tasks were:
| Task 1 | Identify Capabilities and Deficiencies of Existing Methods | ||
|---|---|---|---|
| Task 2 | Develop an Improved Conceptual Framework for Capacity and Level of | ||
| Service Analysis | |||
| Task 3 | Select | a | Suitable Simulation Model and Identify Desirable Functional |
| Improvements | |||
| Task 4 | Prepare Interim Report | ||
| Task 5 | Collect and Analyze Data | ||
| Task 6 | Enhance, Calibrate, and Validate the Selected Simulation Model | ||
| Task 7 | Develop Revised Capacity and Quality of Service Analysis Procedures for | ||
| Two-Lane Highways | |||
| Task 8 | Prepare Final Report | ||
This report deals with Task 6 "Enhance, Calibrate, and Validate the Selected Simulation Model". The objective is to report accomplishments on TWOPAS model code upgrading and documentation and to document all TWOPAS model improvements.
