Appendix A

This appendix details the traffic generator templates available in Passenger Data

Constant traffic (% building pop per 5 mins)

Elevate will produce traffic based on the Demand specified between the Start Time and End Times entered.

The Demand is entered as a percentage of the building population per 5 minutes.  Traffic is divided into three parts, % incoming, % outgoing and % interfloor.

Between the Start Time and End Time, random numbers determine the time each passenger arrives over the duration of the simulation.



Figure 41   Example Passenger Demand graph for Constant Traffic


Step profile

Elevate generates the traffic based on increasing Demand.  At the start of the simulation the demand is at the Minimum level.  It then increases in steps until the Maximum level is reached.  The Time duration, as well as the Step height can be defined.

Traffic is divided into three parts, % incoming, % outgoing and % interfloor.

Barney one hour up peak template

Elevate generates a one hour traffic profile which rises to the required peak Demand for 5 minutes, then drops again.  Over the hour, 80% of the population are transported.

For Dr Barney’s discussion of this template, please refer to Elevate on the web.


Barney one hour down peak template

Elevate generates a one hour traffic profile which rises to the required peak Demand for 5 minutes, then drops again.  Over the hour, 80% of the population are transported.

For Dr Barney’s discussion of this template, please refer to Elevate on the web.


Barney one hour lunch template

Elevate generates a one hour traffic profile.  The profile consists of four 5 minutes bursts of traffic at 1 times, 1⅓ times, 1⅔ times and 2 times the peak Demand.  Between these four bursts of traffic, the traffic is maintained at one tenth of the specified peak Demand.

The traffic generated is divided into three parts, 40% incoming, 40% outgoing and 20% interfloor.

Barney one hour interfloor template

Elevate generates a one hour traffic profile based a non-peak traffic situation.  The total traffic Demand, as a percentage of the building population, is 2% for 20 minutes, then 3% for 20 minutes, then 4% for 20 minutes.

The traffic generated is divided into three parts, 10% incoming, 10% outgoing and 80% interfloor.

Powell 2 hour lunch template

Elevate generates a 2 hour lunchtime traffic profile appropriate to the building population.

The population of individual floors is used to determine the distribution of arrival rates across the floors, and the attraction of each floor as a destination.

Powell 40 minute lunch template

Elevate generates a 40 minute lunchtime traffic profile appropriate to the building population.

Siikonen full day template

Elevate generates an example all day traffic profile based on a sample multi-tenant office building in Paris. The traffic intensity data for this template was published by Dr Marja-Liisa Siikonen in Elevator Technology 10, Proceedings of Elevcon 2000.

Siikonen full day (24 hour) template

This is the same as Siikonen full day template except that the simulation runs for the full 24 hours rather than between 07:00 hrs. and 20:00 hrs.  This can be helpful if you want to calculate the energy consumption of an installation for a full 24 hours.


Strakosch full day template

Elevate generates an example all day traffic profile based on the traffic profile presented by Mr George Strakosch in The Vertical Transportation Handbook.  The profile is based on the requirements of a commercial office building.

Strakosch full day (24 hour) template

This is the same as Strakosch full day template except that the simulation runs for the full 24 hours rather than between 08:00 hrs. and 18:00 hrs.  This can be helpful if you want to calculate the energy consumption of an installation for a full 24 hours.


Strakosch residential template

Elevate generates an example all day traffic profile based on the traffic profile presented by Mr George Strakosch in The Vertical Transportation Handbook.  The profile is based on the requirements of a residential building.

Strakosch school template

Elevate generates an example all day traffic profile based on the traffic profile presented by Mr George Strakosch in The Vertical Transportation Handbook.  The profile is based on the requirements of a school building.

Strakosch hotel template

Elevate generates an example all day traffic profile based on the traffic profile presented by Mr George Strakosch in The Vertical Transportation Handbook.  The profile is based on the requirements of a hotel building.

CIBSE full day template

Elevate generates an example all day traffic profile based on the traffic profile presented by Dr Gina Barney in CIBSE Guide D, Transportation systems in buildings.  The profile is based on the requirements of an office building.

CIBSE full day (24 hour) template

This is the same as CIBSE full day template except that the simulation runs for the full 24 hours rather than between 07:00 hrs. and 20:00 hrs.  This can be helpful if you want to calculate the energy consumption of an installation for a full 24 hours.


Peters Research (CIBSE) modern office up peak

Elevate generates an example morning up peak traffic profile based on multiple traffic surveys undertaken by Peters Research Ltd.  The profile is based on the requirements of an office building. The simulation runs between 08:30 hrs and 09:30 hrs.

Peters Research (CIBSE) modern office lunch peak

Elevate generates an example morning up peak traffic profile based on multiple traffic surveys undertaken by Peters Research Ltd.  The profile is based on the requirements of an office building. The simulation runs between 12:15 hrs and 13:15 hrs.

User (5 minute periods)

Elevate creates a template based on the total demand for each 5 minute period entered by the user.  Traffic is divided into % incoming, % outgoing and % interfloor according to the values entered.
