- Basic Signal Control Concepts (1 week)
- Fundamentals of Signal timing and Delay (2 weeks)
- Intersection Design and Layout (1 week)
- Capacity Analysis of Signalized Intersections (1 week)
- Actuated Signal Control and Loop Detectors (1 week)
- Signal Control of Isolated Intersections (2 weeks)
- Signal Control of Coordinated Intersection Timing (2 weeks)

Meets for 3 hours of lecture and 3 hours of laboratory each week for 10 weeks.

AutoCad and extensive use of such extisting traffic simulation and analysis software as Synchro, SimTraffic, and Highway Capacity Software (HCS).

- Traffic control design for selected urban networks using computer simulation and signal and freeway performance analysis. Lab reports.
- Intersection Design: Students design an intersection layout, lane geometry, and channelization under particular traffic volume considerations. (Lab 1)
- Capacity and Level-of-service (LOS) Analysis of an Isolated Intersection: Students use the HCS to determine LOS under particular traffic volume considerations. (Lab 2)
- Design of Actuated Intersection Signals: Students are given vehicle arrival patterns at an isolated intersection, and asked to design a control strategy that minimizes total delay at the intersection. (Lab 3)
- Intersection Design for Actuated Control: Students design an intersection layout, lane geometry, channelization, and detector placement for a particular actuated signal timing plan. (Lab 4)
- Design of coordinated network signal control scheme: Students are given vehicle arrival patterns at intersections along a corridor, and asked to design a control strategy that maximizes the through green band. (Lab 5)

Contributes toward the Design experience and Engineering topics courses for the Civil Engineering Major.

The approach taken is to follow every engineering principle discussed or derived in class with concrete examples of how that principle is applied in the design of signal control systems for traffic management.
