IDLEAIRE INSTALLATIONS, STATEWIDE

RACM Analysis

Control Measure:

IdleAire Installations

Description:

Long haul truck drivers idle their trucks to heat or cool their cab during the federally required 10 

hours rest period for every 11 on the road. Idling results in poor rest for the driver, consumes fuel 

while moving no product, reduces engine life, requires additional engine maintenance, and 

pollutes the air. IdleAire allows drivers to shut off their engines and provides the cab with heating 

and/or air conditioning. IdleAire also provides electrical outlets and a variety of communication 

and entertainment options for the driver. A total of 210 parking spaces at truck stops would be 

equipped with IdleAire technology statewide. The installations would be located in the following 

counties:

Methodology:

Emission factors, generated using MOBILE6.2, were applied to the number hours of idling 

reduction assumed in order to obtain the emission benefits of installing IdleAire systems 

statewide.

Inputs/Assumptions:

 Trucks are operated 306 days per year

 Of the 306 operating days, 153 are assumed to be summer days and 153 days are 

assumed to be winter days for the annual analysis

 A total of 210 IdleAire systems would be installed statewide

 It is assumed that idling during legally required rest breaks, 10 hours for every 11 hours 

on the road, will be eliminated through 100% utilization of the 210 IdleAire installations.

 MOBILE6.2 was used to determine the average idling emission factors (g/hr)

Cost Benefit Analysis:

Inputs/Assumptions:

 The manufacturer (IdleAire) installs, operates and maintains the equipment at no capital 

cost to the property owner.

 Each truck must have an adapter to use the IdleAire systems. The adapters can be 

purchased for $10.

RACM Analysis

 Dividing by 306 days in the year annualized the daily cost of the adapters. It was also 

assumed that each of the 210 spaces would be used by a different truck which would have 

to purchase an adapter for the first time.

 The annual adapter cost was calculated by assuming only 75% of the trucks using the 

IdleAire spaces would be required to purchase new adapters. 25% of the trucks were 

assumed to already be utilizing adapters.

 The service charge per space is $1.50 per hour retail and $1.25 per hour for fleets with 

contract agreements.

 2/3 of the trucks using the spaces will pay retail, while 1/3 will pay the contract 

agreement price.

 Long-duration idling costs truck owners $1.13 per day, based on the need for more oil 

changes and sooner overhaul costs.

 The average truck consumes 0.8 gallons of fuel per hour of idling.

 The average cost of diesel fuel in New Jersey is $2.62/gallon.
