The Business Case
5
Terrible News! Claims are going through the roof!
6
2011 Nationwide Bus Casualty and Liability Expense Source FTA NTD Casualty and Liability Amount Vehicle- related $483,076,010. Total Buses 59,871 Sub-Total Casualty and Liability Amount Per Bus $8,069/Bus/Year
8
Key Business Model Cost of Active Collision Avoidance < Present Value {Expected Liability Savings over life of bus}
9
Liability Savings pay Cash for the Technology, and… “half” of the following come for FREE!

By walking to a station/aTaxiStand – At what point does a walk distance make the aTaxi trip unattractive relative to one’s personal car? – ¼ mile ( 5 minute) max Like using an Elevator! “NJ Transit aTaxis” Service Model Elevator
16
By walking to a station/aTaxiStand – A what point does a walk distance makes the aTaxi trip unattractive relative to one’s personal car? – ¼ mile ( 5 minute) max By using the rail system for some trips – Trips with at least one trip-end within a short walk to a train station. – Trips to/from NYC or PHL Spatial Aggregation

By walking to a station/aTaxiStand – A what point does a walk distance makes the aTaxi trip unattractive relative to one’s personal car? – ¼ mile ( 5 minute) max By using the rail system for some trips – Trips with at least one trip end within a short walk to a train station. – Trips to/from NYC or PHL By sharing rides with others that are basically going in my direction – No trip has more than 20% circuity added to its trip time. Spatial Aggregation
