Inspiration

2015 link

An incident back in 2015, where the Holy City was rocked by the terrible disaster of stampede and rush in the Kaaba inspired us to make solve this problem and ensure that such a disaster never takes place again.

What it does

It is a system that calculates Space-Time Density of hujjaj karam and (incoming and outgoing) Flux of hujjaj karam passing through the entire Kaaba in real time. The system makes sure that all traffic flow is kept at the optimum max and the density of traffic is also at the favorable maximum. These calculations are done on a Micro-Level (individual haji) as well as on the Macro-Level (group of hujjaj).

The entire layout of the Holy Kaaba is divided into 3 basic types of spaces:

1. Ritual Performance Area
2. Walkways
3. Waiting Area

The hierarchy of the users involved is as follows:

1. Muallim
2. Staff reporting to Muallim
3. Haj Group Leader
4. Individual Haji

The staff reporting to the Muallim will be present at all the spaces to make sure that the Hujjaj Karam are stopped and allowed to leave areas as per the schedule dictated by the system (through red and green lights)

This system accurately predicts regions of high density and flux of the and can therefore recommend efficient dispersion of the hujjaj so that there is no stampede and congestion leading to other health issues (again the staff present will need to disperse the traffic).

The system will be communicating with the Hujjaj Karam and Group Leaders and the Muallim and their reporting staff with the communication module. (Android app)

Allowed values for each of these areas needs to be calculated for perfect and practical deployment of this system.

How we built it

Basic logic and models of flow control, fluid dynamics and traffic prediction along with traffic management equations: link The following graph also shows the simple relationship between KC(Critical Density) and Q(Max Flow)

Challenges we ran into

Creating another layer of data to handle the Mesoscopic Layer (Spacial-Time data for Muallim layer) requires iterative solution of Differential Equations of a very high order and this computation gets very tricky,

Accomplishments that we're proud of

A holistic algorithm which is capable of handling any type of foot traffic in a given space. This can serve well in other congested areas where there is abundant foot traffic e.g. Large concerts etc.

What we learned

We learned that without some sort of data collection mechanism like a wrist band for every haji or GPS enabled smart phone it will get very difficult to accurately predict and schedule the foot traffic.

What's next for O-93-hajjease

A 2030 vision which would be able to holistically provide a complete solution for end to end ease for the haji. We believe that all the mentioned categories and even more have to be included to provide a complete solution.
