MAJOR ISSUES TO CONSIDER
•Pilot a cutting edge program
• Wanted to try an alternate fuel to be a part of the Green
Initiative
• Pending new regulations, additives etc. were changing for 2010
• Battery powered electric too expensive
•Clean burning fuel
o Minimal impact to the environment
•EPA requirements for emissions were met with Propane power
• Capacity size was not affected
• Quiet ride
Planning for Propane
•Decided to look at 3 types of Routes to measure efficiency.
oBus 1 - Long Distance Route to neighboring County – Few
stops
oBus 2 - Inter-city run. Congested traffic/Frequent stops
oBus 3 - A1A Corridor / Long Run – Moderate to Frequent
stops
•Found that buses would need to refuel daily as each could travel
for approximately 1 ½ days on a tank of fuel.
•Results were satisfactory overall, with the exception of miles per
gallon.
•Fuel for buses is significantly less expensive.
