pedx | Python tools for working with PedX dataset | Machine Learning library

I am trying to do an epidemic spread modeling where all the agents are moving in a continuous space. All the agents have a certain "fieldOfVision" area. If within this "fieldOfVision" of a "susceptible" agent another agent who is "exposed" comes & stays for 5 or more minutes, then that susceptible agent will also become "exposed". If that "exposed" agent comes & stays for less then 5 min, then the "susceptible" agent will remain in "susceptible" state.

My agent's statechart is like below:

Initially 6 agents will be "exposed" by sending some msg from main. As the agent is also a pedestrian type agent, at time zero, there is no agent to receive the msg. So, I had to send the msg from main after 3 min of model startup so that someone is receiving the msg. That is working well.

The first transition action from "susceptible" state is as below. I put transition timeout 3.1 min because at 3 min there will be some exposed agent for the first time.

If no one is nearby or within "fieldOfVision" then "noExposedNearby" transition will be executed as below.

If there is someone "exposed" within "fieldOfVision" then "foundExposedNearby" transition will be executed as below and will again go through the same loop until that exposed person is out of the "fieldOfVision"

if that exposed person left from the "fieldOfVision" triangle then "exposedNearbyLeft" transition will be executed as below and will calculate the final time.

exposedNearbyLeft transition]5

then the "probablyExposed" state will calculate the total exposure time that "exposed" agent was near that "susceptible" agent & will check whether it's more than 5 or not. If it's more than 5 then it will go through "enoughExposure" transition otherwise it will go through "notEnoughExposure" & will be back to susceptible state again.

problem is, during runtime after the 7 min, I am getting this error. It seems, my code is not able to get the value of pedX & pedY after sometime. My question is how I can continue that loop & look for the duration that nearest exposed agent and statechart's susceptible agent are within each other's "fieldOfVision"? Is there any suggestion to do so?

It's a long post to read through. If you have come this far, first of all I thank you for your patience. Moreover, I will be really grateful if you can share some thoughts on how I can get the agent's dynamical distance to check whether someone is newly exposed or not. Will really appreciate your feedback.

I am trying to write a code for one state to another state transition where the system will first store the initial model time and then will check a condition (used while loop). It will continue to run the loop until the condition is false and when the condition is false it will record the final model time. So, my main objective is to get the total time that while loop condition is true. The problem is, I don't know how to check the while loop every 1 time step, For example, I tried "wait (1);" in place of "???" section of the below code which is not correct. Can anyone please suggest how I can do this?

My transition code as below: ... ...

initialTime=time();
