What is SCOOT Adaptive Signal Control?

4

• Adjusts signal timing

in real-time to match

traffic patterns.

• Combines data from

multiple sources.

• SCOOT is the

algorithm we have

selected as

recommended by

System Engineering

report.

Project Background

• In 2015, initiated planning process including

systems engineering evaluation.

• Selected adaptive system in accordance with

compatibility to existing signal management

platform.

• Developed a phased implementation plan

that packages adaptive deployment into 3

separate phases.

PERFORMANCE MEASURES

• Internal to SDOT staff

• Detailed reporting to evaluate system performance

Internal Performance Measures

• External to users of the corridor

• High-level metrics to show benefits experienced by user

Public Facing Performance Measures

Page 15: Mercer SCOOT Adaptive Signal Control · Presentation Overview • What is SCOOT adaptive signal control? • Project background • Project phases and more future SCOOT corridors

Investment-Oriented: number of

engineers/technician invested, amount of

money spent on equipment upgrades,

amount of time since last re-timing, etc.

Outcome-Oriented: determines whether

the control plan is effective, whether

equipment needs maintenance, where

capital investments might be needed, etc.

Public-Oriented: complaints, etc.

Metric Types Outcome-Oriented Layers

INTERNAL PERFORMANCE MEASURES

Outcome-Oriented Metrics for an Arterial

Intersection: signal data unique to the

intersection. Performance measures can

include red/green allocation, occupancy

ratio, arrival data, etc.

Arterial: aggregate intersection data and

travel time data. Performance measures

can include travel times, before and after

studies, corridor progression, etc.

Network: aggregate arterial data.

Performance measures can include

origin-destination studies, travel patterns,

etc.

User Cost per Year = Change in Travel Time x Value of Time per Hour =

23 hours (change in travel time) x $17.67 (value per hour) = $406.41 per vehicle per year.

$406.41 (per vehicle) x 14,000 (vehicle throughput) = $5,689,740 yearly savings

User Cost – Calculation assumes SOV, no trucks, peak hours only (WB AM, EB PM)

Return on Investment per Purdue Report Calculations

Fuel Consumption

Fuel Consumption = Change in Travel Time x Average Fuel Consumption =

23 hours (change in travel time) x 0.87 gal/hour (avg. fuel cons.) = 20 gals, per person per year.

20 gals (per vehicle) x 14,000 (vehicle throughput) = 280,000 gallons

Assume $3 per gallon = $840,000

Carbon Cost = CO2 tons x Social Cost of CO2 =

2,683 tons CO2 (peak period vehicles) x $36 per ton (per EPA) = $96,617

CO2 Emissions = Fuel Consumption x CO2 Emitted per Gallon of Gasoline =

280,000 gallons (peak period vehicles) x 19.17lb/gal (per EPA) = 5,367,600 lbs = 2,683 tons CO2
