Hi I was wondering if someone could help me with a network / routing challenge. The main aim of this task is to estimate the flow of pedestrians/ people who move on the road network from their start locations toward a final destination. The origins is a points layer where every point includes a field that counts the number of people who live in that point location. Further, we have the destination point (another points layer) where all these people will travel to via a road network layer. Using the closest facility tool with the road network dataset ,origins and destination we could obtain the closest route from every origin to the destination as can be seen below: After obtaining the closest facility above, we did an intersection between the original network (dark blue network) and the closest facility route (Purple network) to find how many times every segment has been traversed by every point. However, this method assume that every origin point has the same number of people which is not true. Every point has different number of people who live in that location/origin. So instead of calculating the number of times every road has been passed by every route, we need to calculate how many people/pedestrians who passed every road towards the destination. As the closest facility route table result does not contain the number of people who are occupied in every point, I am thinking that there is a way ( within Arc GIS) which can calculate the number of people who pass via every road. Personally , I think there is some way to calculate it within the closest facility to know how many people has traversed via every road. Any idea how to do it please

Thanks Melinda for your answer as you know that the output attribute data of the route layer include some data such as: FId, Shape, ObjectID, FcilityID, FacilityRA, Name, IncidentCU, FacilityCU, IncidentID, Totalleng, Shapeleng and RouteID. Hence, No data about people number will be attached to routes after running the model. Further, If I select to run "Copy Traversed Source Feature", this tool does not run? for that reason, both options does not help.

I have found how many times every segment has been used by the selection by location , between the original network ( segments layer) and the closest facility route layer. Then , I used summary statistics as you mentioned. In this context, I would like to clarify that the number of people is known for the whole route not for every segment. Hence, how the whole route number can be calculated via every segment if possible?

I have a layer of number of people in every area as points . Say like Point A has 100 people and Point B has 1000 people. I would like to calculate the most congested route/ street in the network. I have succeeded to find how many every segments has been traversed by these points via closest facility tool. Now, Its know every segment how many times its been traversed but we need to know how many pedestrian who passed this segment. For example, if segment X has been traversed 3 times by point A= 100 pedestrian and B= 200 ped and C= 300 ped. This mean segment X should be passed by 600 people and so on. From the above mentioned explanation, is there any tool in network analyst could help to calculate pedestrians who pass through every segment or any other idea pls?

Thanks Melinda for your suggestion.. its much appreciated. I followed your suggestion and uploaded the closest facility layer, however, its not executed properly. the message response as following : any help to figure out ? Many thanks in advance, Muteb

I have some demand points every one represent a particular population number. Using the minimise impedance we need to know the nearest demand to the facilities which cover these demand points. However, how can I set up a capacity constraint that every facility must not cover (i.e more than 1000 population to see how the population are being covered with the maximum capacity of every facility) Any help how can I do it in Network analyst?

Many thanks Jay I did use Minimize Impedance I examined multiple transportation network.  I did use two softwares : Arcgis and Arcgis Pro  I used the route function to explore the distance of these 11 points and found another facilities nearer to them rather than the current facilities. I am really confused why this happen?
