wage projection
Wage Projection

Wage Data is available from 1951 to 2006.

Regression Analysis indicates strong fit (R-square = 0.998).

According to Social Security Online (www.ssa.org), national median wage is about 70% of national average wage.

Future year TTVs are calculated based on projected median wages.

11

travel time values 2004
Travel Time Values (2004)

Annual median wages from 2000 census: SEFL = $21,975; FL = $20,721

Median income is about 70% of average income.

12

commercial vehicle travel time values 2004
Commercial Vehicle Travel Time Values (2004)

Annual median wages from 2000 census: SEFL = $21,975; FL = $20,721

Median income is about 70% of average income.

vehicle operating cost assumptions
Vehicle Operating Cost Assumptions

Vehicle class types – compact, mid-size, large, SUV, Minivan, and trucks

Driving range – 12,000-15,000 miles per year

Vehicle lifespan – 150,000 mi

Southeast Florida

Urban setting

Flat surface

16

default assumptions
Default Assumptions

Urban settings assumed in South Florida

City conditions generate 35% more fuel consumption than highway conditions

About 3% annual price increase applied to maintenance and repairs based on historical (20-year period) CPI trends

18

vehicle operating costs fuel cost
Vehicle Operating Costs – Fuel Cost

$/gallon = $1.53-$1.65 (2004)

25

vehicle operating costs financial charges
Vehicle Operating Costs – Financial Charges

Average interest rate = 4.45% (2004)

Financial Charges = Interest on vehicle loan

26

vehicle operating costs fuel tax
Vehicle Operating Costs – Fuel Tax

Federal = 18.4 cents/gallon

State = 14.3 cents/gallon

Local = 6-12 cents/gallon

27

transit operating costs
Transit Operating Costs

Service and cost data obtained from National Transit Database (NTD) - Federal Transit Administration

Modes:

Bus; Demand Response; Commuter Rail; Light Rail

Data:

Services: passenger trips; revenue hours; revenue miles

Costs: operators’ wage; material and supplies; utilities; insurance; tax; purchased transportation; ADA related expense; other expenses.

Unit cost = (total costs)/(total services provided)

4 sample applications
4. Sample Applications
  • 1. Lane closure cost calculation
    • Hypothesis scenario
    • Additional cost for roadway users (TTV + VOC) resulted from lane closure
  • 2. Trip cost comparison for Auto and Transit
    • Cost for roadway user (TTV + VOC) and transit user (TTV + fare)
    • Downtown Coral Springs to Fort Lauderdale
sample application 1
Sample Application 1

Left Lane Closure on I-595 from University Dr. to FTPK

Conditions

2009, 2 days, 2.2 miles

AADT 227,000

Average occupancy: 1.2 people per vehicle

Average travel speed reduced from 55mph to 35mph

TTV in 2009: $8.16 per hour

VOC at 35mph: $0.471/mile; VOC at 55mph: $0.461/mile

Costs

TTV increased : (2.2/35 – 2.2/55)*8.16*227,000*1.2*2 = $101,613

VOC increased: ($0.471 – $0.461)*2.2*227,000*2 = $9,988

Total cost = TTV + VOC = $111,601
