Demand Characteristics• Passenger Counts

- Daily/ Monthly/ Annual- # Boardings- Student’s Peak AM and PM

• Existing and Projected Student Enrollments• % Students using Transit• Load levels/ Load Factor

Route Performances• Existing Campus Routes• Running Time

On-time performance (ASK what TCAT’s criteria are?)Adherence to Arrivals and Departures for each identified stopsLate Buses what are the impacts/ implications (e.g. any “linked late”)? What are the causes?

• Customer Comments• GIS Data on Route Alignments & Stops

Economic Implications• Day-by-Day Farebox Information• TCAT’s Replacement Plan• Revenue Miles and Revenue Hours• TCAT’s Cost Allocation for Cornell routes/ Cornell’s Subsidy

Some Possible Decision Criteria

I. What is/ are the most utilized route(s)?• Daily ridership• Average number of passengers/trip• Peak demands• Load factors

II. Which route(s) has/have an issue with on-time performances?• Reliability (% on time AM/PM)• Average schedule deviation (minutes)• Operating speeds—Scheduled versus Actual

III. Which is/are expected to experience the increasing demand?IV. Which is/are usually reported full?V. Others

• Farebox, Revenue miles/hours• Customer satisfaction

Schedule Deviation (need to present both AM and PM)Route Run Time Period Deviation from

Schedule (minutes)

NOTE: The average schedule deviation is calculated by 1) summing over the individual trip deviation

2) dividing the sum by the total trips. (Assume: daily basis)

Definitions:i. Current Cost = current daily costsii. Route Revenue = daily costs that are recovered from farebox and pass salesiii. Route subsidy = amount of additional money needed over and above farebos revenueiv. Subsidy per Passenger Mile = Route Subsidy divided by passenger milesv. Subsidy per Passengers = Route subsidy divided by total passenger boardingsvi. Farebox Recovery Ratio = % of the operating costs that is recovered from farebox and pass

salesvii. Passengers per Revenue Hours = the number of passengers carried per hour that the bus is in

service

Some Recommendations mentioned in the Article Replacement of the 40-ft bus by the 60-ft articulated bus Bus reallocation

Adding buses Adding or decreasing the running time Introducing the express services on the routes that meet specified LFs Route alignments Route redirecting
