 ## Notations

The alphabetical order notations below if for your reference in this tutorial. You can refer back later if necessary. = Portion of distance per trip (half of the cycle) that normally traveled by all passengers (percent) = Total benefit after conversion into present time value (\$) = Total cost after conversion into present time value (\$) = Interest rate (percent) = Period of usage year that a bus can be operated from purchasing time until is sold again (years) = average distance travel of by all passengers (km)

One cycle is from origin station to destination station and back to origin station again. = Number of cycles (origin->destination->origin) that a bus can operate in one day (cycle/day) = Benefit of a bus system from the operation per day (\$/day) = Total distance that a bus will operate in one day (km/day) = Total distance that a bus will operate in one cycle (km/cycle). = Monthly salary of a bus driver (\$/month) = Price of engine oil per can (\$/can) = Payment that passenger that received by the system (\$/passenger) = Price of the bus after usage year (\$) = Gasoline price per liter = Purchasing cost of one bus (\$) = Average fluctuation of demand in that particular route (1/cycle) = Average speed of operation that include the effect of traffic congestion (km/hour) = Number of passengers in one cycle (passengers/cycle). = Time reduction due stopping time to boarding and alighting of passengers along the way and some reduce time due to slowing down to get the passengers (hour/passenger). = Total number of hours spends by a bus to operate in one cycle. = Total yearly administrative (tax, vehicle inspection, administrators) and simple maintenance such as cleaning and painting (\$/year) = Total benefit in one year (\$/year) = Total distance of bus operation throughout one year (km/year) = Bus driver salary for one year (\$/year) = Total cost due to engine oil for the operation of the bus (\$/year) = Total cost due to gasoline for the operation of the bus (\$/year) = Total operating cost in one year (\$/year) which include all operation, administrative and maintenance cost but exclude initial purchasing cost. = Total cost due to tire for the operation of the bus (\$/year) = Total distance of that a bus can run using one can of engine oil (km/can) = Total distance of that a bus can run using one liter of gasoline (km/liter) = Total distance of that one tire in a bus can run until need to be replaced (km) = Total number of passenger can ride a bus (passengers) = Number of working day per year that the bus can be operated
