"There's hoards of cells!! - What do I do? Don't worry - They are already set up with sensible defaults so you generally only need to alter a few of them in order to play about and see what effect they have. To help with this here is some information on what each cell means: Number of buses: - Self-explanatory. Enter any number up to 20 Number of stops: - Number of bus stops on the route. Enter any number up to 25. (You will need to make sure that there is information on passenger arrival and alighting rates for each stop - see later). Acceleration/Deceleration time: - The amount of time (in minutes) that is lost when the bus has to slow to a stop and then accelerate to normal speed when it has to stop to pick up or drop off passengers. This does NOT include the time spent stood still at he stop whilst passengers embark etc. Maximum Load: - Maximum number of passengers allowed on the bus. The bus will never pick up more than this value so this can mean that passengers will be left at a stop or a stop will be avoided if the bus is already overcrowded. Passenger boarding/alighting times: - Average amount of time (in minutes) taken for a passenger to board and alight (get off) the bus. The boarding time is typically longest due to paying the driver etc. Average velocity: - Average speed of the bus in km/h (doesn't have a major impact on things) Number of iterations: - The number of time the model is run. The output values will be the average from all the runs. There are several aspects of the model that rely on a degree of chance (random variations). Entering a value of 10 or more will tend to average out these effects. Entering 1 will run the model only once, and can show more exaggerated effects than running it several times since the effects of chance are then evident. Traffic Delay: Preceding bus stop number: - A temporary delay due to heavy traffic or roadworks etc can be simulated in the model. Define the location here by entering the bus stop before which the delay is to occur. Traffic Delay: Start Time: - Enter the elapsed time after the start of the model at which the delaying situation starts. Traffic Delay: Peak Time: - Enter the elapsed time after the start of the model at which the delaying situation peaks. Traffic Delay: End Time: - Enter the elapsed time after the start of the model at which the delaying situation ends. Traffic Delay: Maximum delay: - Enter the time delay caused to a bus at the peak of the delaying situation.   Bus Start Times: - Enter a start time (in minutes) for each bus, bus 1 having the earliest (and typically being zero). This can be though of as the time at which the buses leave the depot. The adjacent (grey) cells will update with the time intervals between sequential buses. Bus Start Time Random Variation: - A value (in minutes) entered here defines an upper limit for a randomly generated fluctuation around these start times. For example a value of 1 means that the actual start times for each bus can be up to 1 minute earlier or later than the specified start time. This aims to reflect real-life variability and inaccuracies.   Bus Route Information Section: - Information entered here defines the characteristics of the bus route.The activity in terms of the rate at which people turn up, or disembark, at each bus stop can be different for each stop. Some can be busy whilst others only see scant activity. Number of people arriving per minute: - The rate at which people turn up to each stop can be entered here. Either enter a value or use the drop-down menu to specify a pre-defined level of activity. Max percentage of passengers alighting: - The number of people getting off at each stop is to some extent random, but the maximum is defined as a percentage of the number of people already onboard. Distance from previous stop: - Self-explanatory, and has little effect on the overall outcome.
