The cost coefficients include: vehicle cost (fixed and variable), crew cost (fixed and variable), service benefit, and other costs. The performance criteria include: measures of passenger service, measures for vehicle and crew schedules, and measures for duty rosters, and other criteria. This chapter includes two main parts. The first covers the determination of vehicle frequencies and the construction of alternative public timetables for both cases of 34 Advanced Modeling for Transit Operations and Service Planning even headway and even average load.

In order to avoid this imbalanced situation the following principle is exploited. 7:00 Figure 2. Determination of the example departure times (at A) for evenly spaced headways with a smoothing process between time periods 71 passengers; significantly above the desired 50 passengers. In order to avoid this imbalanced situation the following principle is exploited. Principle 2: construct a curve representing the accumulative loads observed on individual buses at the hourly max load points. Moving horizontally per each dj for all j, until intersecting the accumulative curve, and then vertically, results with the required departure times.
