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 ... View more

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? ...

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? ...

It is usually that Location Allocation model would link the nearest facilities to the nearest demand points. However, In my project, most of the demand points are serviced by the nearest facilities except about 11 points. I tried both Arcgis and Arcgis Pro both gave me the same results. In addition, when I use another facility layer the problematic points number change, I think its related to the location of the facilities as the demand points are fixed. Could anyone please give any thought why this happened, even though, I used 4 type of network layers to reassure that no problem with network itself? ... View more

I have an area in google map which I know what is its coordinate Lon/Lat but the canvas border in Qgis is defined on X/Y based to download a mapstreet map? I tried many time using this website  https://epsg.io/transform#s_srs=4326&t_srs=2318&x=21.4150000&y=39.9100000)  to convert my coordinates however the coordinates that been generated does not work with Qgis? any help please to solve this problem? ...
