Re: [sumo-user] Modify pedestrian dynamic model

Thank you Mr.Jakob
Let me briefly introduce my healthcare environment: individuals move with AGV. The AGVs are only to transfer materials in the environment (a flat floor) like the following picture. AGV might meet pedestrians who include: staff (S for short), visitor (V for short), patients - move like normal (N for short) and individuals with disabilities (D for short)

Therefore I need some improvement:
(i) in XML, the personFlow needs new attributes, for example: disable (a probability indicates the person is D or not). If a pedestrian is D type, he might have a stick or crutch or wheeled-chair or even he is bind.
(ii) In the intersection, D person (who has a slower velocity) might be carried by other S, V or even N people for crossing, especially as the D is moving in a crossway. After leaving the crossway, D person could be left alone.
(iii) A pedestrian will have different gap acceptance (a distance between person to the AGV). If the distance is too short, he/she would decide to stay at the waiting area.

The gap acceptance of a pedestrian depends on yielding of vehicle (too loud or not), healthy of the person as well as the number of AGV's platoon
Looking at the code of Omnet++ and SUMO, I still don't know which files to modify. If it is too difficult to change the code, perhaps I have no choice but to use a quick and dirty hack to get my purpose.
Thank you in advance

Some comments:
- the paper ""Modelling pedestrian dynamics in SUMO" doesn't describe the whole set of vehicle/pedestrian interactions that are currently implemented
- the SUMO team is currently engaged with the integration of "social force" style pedestrian models by way of JuPedSim (,

Can you describe the interactions that you need to simulation in more detail?

Dear all
As reading the papers: "Modelling pedestrian dynamics in SUMO" and "Pedestrian Simulation In SUMO Through Externally Modelled Agents" I notice that the current pedestrian model in SUMO is very simple.
In my work, I need a pedestrian model which reflects a healthcare environment. In this model, I intend to implement interaction between vehicles (Automated Guided Vehicle) as well as individuals with disabilities
I still don't know how to implement a new pedestrian model in SUMO, could I need to modify the code of Viens?
Does anyone have a hint for me by chance?
Thank you in advance
