About LEGION Simulator
LEGION Simulator enables you to run, record, replay and analyse simulations using two methods:
- On-line analysis-analysing while simulating using a LEGION Simulator File ('ora').
- Off-line analysis-analysing a recorded LEGION Simulator Results File ('res').
Both methods give you access to a wide range of metrics (density, speed, flow, journey time, dissatisfaction etc.) and a rich array of display methods and outputs including Maps, Graphs and tables.
Simulating without recording is a useful visual tool for checking your model and Entities are behaving as expected. You may find that you need to tweak your model file after viewing the movement of Entities within LEGION Simulator.
LEGION Simulator shares certain tools and features with LEGION Model Builder. To avoid repetition, you are referred to the earlier sections of the guide as appropriate.
Each time you play or record a simulation, LEGION Simulator calculates the movement of every single Entity in its journey through the space you have modelled. Due to the complexity and accuracy of LEGION algorithms, each simulation is slightly different from the last (unless you choose to reuse the identical simulation 'seed', see Specifying the Simulation Seed
LEGION Simulator creates a LEGION Simulation Analysis File ('ana') as a template for storing settings of all Maps, Graphs and Analyses you generate from a LEGION Simulator File or LEGION Simulation Results File. In this way, you can analyse many files using the same analysis template, which is a good way to compare different scenarios.
Basic concept behind Analysis
LEGION Simulator enables you to take your whole model, or a defined portion of it, and ask certain questions tied to the objectives of your project. The following schema details the kind of objectives that typically relate to the four main concerns that LEGION analyses relate to:
Analysis questions
This is far from being an exhaustive list but the following represent the kinds of questions that you can ask as part of an analysis:
- Can the venue cope with projected demand?
- What is the gateline or security check configuration that attains the best flow?
- What are the density levels at bottleneck points such at the bottom of stairs?
- What is the average waiting time at facilities in the peak time?
- Which operational scheme optimises individual visitor/customer experience?
- What is an appropriate location for retail units?
- Are vertical circulation elements effective at clearing a platform before the next train arrives?
- What is the interchange time distribution between lines A, B and C?
- Can the venue be evacuated safely in the case of an incident?
- Will queues in front of facilities impede regular circulation?
By combining LEGION Simulator’s in-built metrics, Analysis Objects and ranges, you can interrogate your simulated space to get answers to all these questions. The most important thing in the whole of a LEGION Simulator project is knowing which questions you need answered.
