Overview

Discussion Points

• Current Transportation Engineering

Practices and Procedures

• Infrastructure Based Decision Making Tools
• Infrastructureless Decision Making Tools
• Combining, Optimizing, and The Future

Civil Engineering = Infrastructure

Transportation Engineering Construction Management Environmental Engineering Geotechnical Engineering Structural Engineering Hydraulic Engineering

Probe Data (Infrastructureless) High Res Signal Data (Infrastructure Based) Current Data

I. Define Objectives, Assess and Prioritize activities by Time of Day and location II. Assembly relevant data to support timing and docu- mentation

III. Software Modeling IV. Timing Design and Docu- mentation V. Deployment VI. Assess

In a sensor based world if you can measure, we don’t really need to model.

Performance Measure Definition Equation Congestion Hours Hours < 45 mph Distance- Weighted Congestion Hours Hours < 45 mph multiplied by the Segment Length Congestion Index Total number of congestion hours along an interstate divided by the total length of the interstate. Speed Profile The number of congestion hours grouped by speed ranges. Speed Deficit The difference between the 45 mph congestion threshold and the actual observed speed. Travel Time Deficit The number of hours of delay occurring where speeds are below the 45 mph congestion threshold.
