Delaware Authority for Regional Transit: DART
Delaware’s bus, train, and intermodal transportation provider Services include contracted SEPTA commuter trains,
intercounty bus, fixed route bus and paratransit
10.2 million passenger trips system wide ridership
Revenue sources: 18% fare – 77% State – 3% Federal – 2% bus advertising
One of the 43 transit agencies chosen to reduce energy consumption and GHG Emissions

Alternative-Fuel Buses
Clean Air Act 1990– Ethanol, Methanol, Biodiesel,
CNG, LPG, LNG, Hybrid,
Pure Electric, Fuel cell
2009 APTA database
(40-foot standard transit bus)

Other Technologies weaknesses
Ethanol & Methanol:– High maintenance cost and reduced engine life
LPG:– Lack of suitable commercially available engine – Practical option for small- to medium-sized transit buses
Fuel Cell:– Very pricy with an average price of $1.3M (zero emission)
Pure Electric:– Prototype design stage (very promising)

Data Collection
DART: – Annual average mileage = 30,000 mile/year– Average speed = 12.7 mph– Bus life span = 12 years– Fuel economy
Delaware Air quality Reports: – key emissions: PM2.5 & ozone– non-attainment areas: Wilmington for PM2.5 & Delaware for
ozone

Data Collection
Federal reports including:– Transit Cooperative Research Program (TCRP) – Federal Transit Administration (FTA)– Department of Transportation (DOT) – National Renewable Energy Laboratory (NREL) – Department of Energy (DOE)– American Public Transportation Association (APTA)
Two major public transportation conferences:– BUSCON 2009, Chicago, IL– APTA 2009, Orlando, FL

Life-Cycle Cost Items
Capital Cost– Vehicle Cost – Refueling Station
(infrastructure)
– Depot Modification
Operating Cost– Fuel Cost– Total Maintenance Cost– Facility Maintenance– Compression Electricity– Battery Replacement
Infrastructure and depot modification cost were justified based on DART current facilities
