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. o Bus 1 - Long Distance Route to neighboring County – Few stops o Bus 2 - Inter-city run. Congested traffic/Frequent stops o Bus 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.
