Private Investment and Performance?

• The annual employer survey asks about different funding amounts• Challenges:

– The existing Employer survey responses to financial questions represent less than half of the 966 worksites in this cycle

– In looking at the provided data, some worksites within the same company have identical numbers reported, suggesting that some financial data may be double-reported

– There are privacy concerns around this information being collected and analyzed

• With the private financial information being incomplete, we cannot draw conclusions based on our current data

CTR Benefit Versus Traditional Construction?

13

VMT reduction of 33 million miles in 2014

This translates to an approximate VMT reduction of 36,000 miles per peak hour

Average throughput during peak period = 1,800 single occupancy vehicles per lane per hour

Per WSDOT 2015 Corridor Capacity Report, averaging SOV throughput per lane on I-5, I-405, SR-520, and I-90 during the peak periods

http://wsdot.wa.gov/publications/fulltext/graynotebook/CCR15.pdf

This is the equivalent capacity of adding a single lane that is 40.3 miles long

Since the program is administered in multiple areas throughout the state, the simple addition of 40.3 lane-miles would not yield the same results achieved by the program.

CTR Benefit Versus Traditional Construction?

14

Theoretical Cost of a 40.3 mile long lane added to the existing freeway

Costs for adding an additional lane to an existing freeway+

$4.1 to $14.7 million per lane-mile in 2015 dollars, small urban area Low estimate of $7.5 million per lane-mile in 2015 dollars, large urbanized area

Cost of adding 40.3 miles From $166 million to $591 million, small urbanized environment A low estimate of $304 million, large urbanized environment

+Per-mile cost of adding a lane is outlined below, per FHWA’s Table 6-1. Elemental Capital Improvement Costs, in 2002 dollars

https://www.fhwa.dot.gov/asset/hersst/pubs/tech/tech06.cfm

*The following calculator was used to convert from 2002 to 2015 dollars. This calculator is tied to the consumer price index (CPI) http://www.usinflationcalculator.com/

Since the program is administered in multiple areas throughout the state, the simple addition of 40.3 lane-miles would not yield the same results achieved by the program.

Right of way acquisition costs vary widely depending on the area. The above estimates may be high for rural areas and low for large urban areas.

Question for the Board

15

Now is a good time to discuss assumptions and methodologies

Additional methods and analyses can be applied to existing program data

Calculations can be simplified, where appropriate

Can the performance committee convene to discuss the above items and more?
