Entrance level bias

This input table is only applicable and active when the Analysis type is Simulation, General analysis or Double Deck General analysis.

Entrance level bias defines the relative demand for incoming/outgoing traffic from/to the entrance floors. The entrance floors must be selected in Building Data before appearing in this table.

If the "Ground" is the only entrance/exit, then set the % bias for this floor to 100.

If, for example, there is a "Basement Car Park," it is likely that some passengers will arrive and leave by this entrance. Considering the number of bicycles, cars and persons per car, then comparing that figure with the total building population, one might determine that, in the morning, 30% of the population enters the building through the basement car park, taking the elevator directly to their office floor rather than via the ground floor. In this instance, the bias could be set to 30% for the "Basement Car Park" and 70% for the "Ground". Elevate will divide traffic between the floors on this basis.

You can see how this is reflected in arrival rate and destination probabilities by switching to Advanced Passenger Data mode. If the traffic flow is more complex than this, the only option is to use the Advanced Passenger Data mode and build your own arrival rate/destination probability tables. An example of a more complex traffic flow would be if people use the lifts to take their bicycles to the basement and then take a second trip up to their office floor.

For double deck elevators, the Entrance level bias is presented in groups of two floors. For example, the bias for "Level -1 and Level -2" could be set to 30%, and the bias for "Level 0 and Level 1" could be 70%.
