Re: Some questions

Hi, I guess that's because you might have missed a step that I didn't mention explicitly. When you go: - one of the entries to the left and right in the model. - right click and go to tab location - go to exit trigger There you'll find a line of code that sends the agents into the indicative corrido...

Re: Some questions

Hi, To come back to your other questions: 1a. You can set the limit of the number of agents in: Agent Generator > Tab General > Max nr of agents. 1b. You can make an arrival distribution in multiple ways. See attached model ArrivalDistribution for a suggestion that might work for you: - Go to the ag...

Re: Some questions

Hi, I''ll start with your question nr 3 first: Activity Locations do have the possibility to trigger agents periodically. See attached example model: agents go to the waiting area and get the activity time "wait until triggered" which is -1. Then: go to the Availability of the waiting area...

Re: Modelling group behavior

Hi, PD doesn't contain (yet) the grouping behaviour for agents. If you want to model this, you could create smalle groups with exact the same speed and same origin and destinations, but they will not necessarily stay together. Another approach could be to model a bigger agent to represent an adult a...

Re: Queuing in PD

Hi, No there isn't a maximum, unless it has been defined in the user settings. Besides the number in the arrivallist, there is another setting that defines the maximum number of agents. Please goto: Agent input > Agent generator > Tab General. In this window check the max number of agents. It is set...

Re: Error: No next activity destination found

Hi, It means that the agent needs to do an activity (a step in the agent activity route), but for the 3rd step in the route it cannot find a suitable location. So, I would suggest to check the tab location of the activity that's in the 3rd step of your route and see if there is something missing. It...

Re: Queuing in PD

Hi, Yes, the outputs for travel times also gives you the mean value (in the legend) and in the tab distances you'll find the mean distance. That gives you the possibility to calculate the avg walking speed. NB the desired/maximum speed of the agents will not change in evacuation, if you expect the p...

Re: Problems with "Local Obstacle"

Hi, Please have a look at the attached example model. What it does: - The localobstacle has default: enabled is false. - Please note the reset code that disables the local obstacle onreset. - The action timer is triggered after 2 minutes. This action timer enables the local obstacle using the the fu...

Re: Queuing in PD

Hello, These settings have the following meaning: - The maximum speed of the agent is in fact the agent's desired speed in uncongested spaces. So an agent will walk at it's maximum speed if possible, but might have to slow down due to congestion. Each agent get's an individual maximum speed, therefo...

Re: Incident element / incident object

Hello, Your approach might work when you use a passageway instead of an opening, but you'll have to make sure that the passageway is placed over a network line to make the networkline not available. However I do think that the local obstacle option will work better. I will send you some info by mail...
