Decision Support Framework and Parameters for Dynamic Part-Time Shoulder Use:
Considerations for Opening Freeway Shoulders for Travel as a Traffic Management Strategy

Long Description for Figure 31. Charts. Compound figure depicts network delay comparison under various decision parameter variations and maximum demand to capacity ratios.

b) Network Delay: Slope Offset = 40; Shoulder Capacity = 1,600 veh/hr.

Graph shows delay in veh.hr on the Y axis and D/C Ratio on the X axis.

At 1.02 D/C ratio, the Delays are as follows: Base, 474; Speed Parameter (45 mph), 321; Speed Parameter (55 mph), 321; Volume Parameter (v=0.8*c), 314; Volume Parameter (v=0.7*c), 251.

At 1.04 D/C ratio, the Delays are as follows: Base, 520; Speed Parameter (45 mph), 327; Speed Parameter (55 mph), 328; Volume Parameter (v=0.8*c), 370; Volume Parameter (v=0.7*c), 283.

At 1.06 D/C ratio, the Delays are as follows: Base, 547; Speed Parameter (45 mph), 363; Speed Parameter (55 mph), 363; Volume Parameter (v=0.8*c), 379; Volume Parameter (v=0.7*c), 338.

At 1.08 D/C ratio, the Delays are as follows: Base, 571; Speed Parameter (45 mph), 373; Speed Parameter (55 mph), 373; Volume Parameter (v=0.8*c), 428; Volume Parameter (v=0.7*c), 353.
