employees each workday.



Idaho National Laboratory

Our Strategy for Reducing Petroleum
Consumption


Increase Lab’s Use of Alternative
Fuels (B20 and E85)


Modify and Right
-
size the INL
Vehicle Fleet (GSA Bus Lease)


Improve the Efficiency of Bus
Operations (Park and Ride)


Aggressively Track and Reduce
Fuel Use (Idling and Driver
Behavior)




INL Fossil Fuel Reduction

*FY2012 Numbers Extrapolated

2012 Fossil Fuel Reduction


Fuel reduction for 2012 has been dramatically lower than target
values to meet the Executive Order.


Cumulative total of reduction for the year has been 110,000 gallons,
and is estimated to be approximately 170,000 gallons
compared to
targeted reduction
at the end of the fiscal year.


Utilization has decreased in the bus fleet, and is extrapolated to
decrease by 93,000 miles. (This change is mostly due to
consolidation of routes, removal of routes, and park and ride).


In addition, reduction of idling time, driver education and behaviors,
and tele
-
work initiatives (such as online meetings instead of on
-
site,
remote work, etc.) has helped to reduce total fleet utilization.


Reduced number of buses from 103 in FY2011 to 94 current.


Possible through GSA lease of over fifty new 55 passenger
motor coaches.


Continuing efforts for fossil fuel reduction


New, more efficient buses.


2 mpg better per bus.


Idle time reduced to 10 minutes via auto
-
shutoff.


Bus simulator research with drivers to improve fuel economy
through changing driver behavior.


Usage of B20 year round.


Use of additives to prevent gelling extreme winter conditions


Research into new technologies for mixed fuel (CNG + B20)


KeyValet Automated Motor Pool:


Better information to help us right
-
size light fleet while
maintaining customer needs.


Note: These efforts will reduce the use of alternative fuel


INL Fleet Resources


Motivation


“10% reduction in fuel = $500k savings annually


Reduce dependency on foreign oil


Fleet Resources


Professional Drivers


Many with over 1 million miles of safe driving


94 Motor coaches


Transport thousands of passengers 100 miles each workday


Standardized routes (repeatability of driving conditions for
different driving styles)


Full system data recorded every second of operation


Full Shop


Highly skilled mechanics


Over 25 years of maintenance logs


Numerous hybrid, electric and alternatively fueled vehicles

The Partners


Provide a sound technical basis for improvements in INL
fleet transportation driver and fuel efficiency


via information presentation and visualization based
on learning algorithms, real time data analysis, and
GPS


Determine improvements

that could be implemented

DOE fleet wide


Increase collaboration


with University of Idaho

faculty and graduate students



Objectives of work

The Human Factor………. Approaches


Competency testing


Self observation use data logs or voice recorder


Conduct quality circles, debrief drivers, condition against
aggressive driving and dominance


Shore up training and licensing


Provide better visibility in vehicle and when designing
highways


Provide additional safety devices


Law enforcement


Improving risk assessment and bias and perception


Provide more or different information (Beyond IMPG)

Mechanical


Maintenance (breaks, alignment, synthetic oil)


Gear choices (for manual switching, not likely) for the motor coach fleet


Regenerative braking (think hybrid vehicles)


Driver Strategies



Try to reduce acceleration and braking to what is really needed



Adjusting speed prior reaching the traffic light


Coasting


Anticipate the actions of other drivers


Burn and coast, also called burn and glide (research on vehicle inertia,
idea is to reduce fuel consumption to zero during the glide)


Difficulties if you have an automatic transmission (torque converter
lockup problems)



Model historical performance, data mine, then introduce predictive displays





Basics for Improving Efficiency

VirtualBus Simulation Available in Exhibitors Hall



Interactive software simulation of longitudinal dynamics of D
-
Series bus (MCI Motorcoach)



Physical model of the environment: gravitation force, rolling
friction force, aerodynamic drag force, engine force, breaking force



Integrated with Beta driving simulator human machine interface



Serves as a development platform for Intelligent Driver System


Good Reviews on this simulation from Industry: Mercury fleet
consultants and MCI (motor coach provider through GSA)

**Strong interest from INL motor coach drivers

read sensor data and


determine if repairs are successful



Networkfleet
®

has devices on MCI buses that read CAN bus data and has a
processor, an upgrade might be able to run our software when complete. They are on
100,000 coaches nationwide

Potential to Lead to Outside Tasking:

At INL, we’re driven to save.
