**4. Case study**

The case study focuses on the road transport sector. Because of the annual rise shown in **Figure 2**, this is the most important sector to minimize risk. At the same time, as the number of transported goods increases, there is an increase in risks as the number of means of transport also increases. Means of transport are a tool for the realization and fulfillment of customer requirements. Customer requirements are essential data for the proposed tool. Meeting the requirements is the most important point before starting the entire transport process.

### **4.1 Planning phase**

In **Figure 3** we can see two points. Point A indicates where the transport unit is to be picked up. Point B shows us where it is necessary to transport the transport unit.

After entering the entry point to load the shipping unit and then determine the delivery location, the route selection will come in line. This phenomenon is shown in **Figure 4**.

**Figure 4** shows the route options from which we can choose the most suitable for us. The tool works as a regular map, giving you the shortest route choices, the fastest or the alternative. The tool does not work based on common data such as a common map or navigation. By setting the input data of the so-called customer requirements, there is a direct definition of the routes that can be implemented in the transport process.

Based on dynamic functionality, the tool marks not only risks but also various constraints on routes, which could limit or disrupt the entire transport process. Reconstructions are usually given in advance together with a possible surface change. All this data is important to the functionality of the tool in order to be able to respond to columns and possibly a large delay on a planned route.

#### **4.2 Real phase during transport**

In this section, we will discuss the functionality of the proposed tool when working in real time. In **Figure5**, we can see a situation that jumps to the operator during the transport process. The vehicle picked up the shipment or material and took the chosen route.

**Figure 6.** *Alternative solution to the situation.*

During the transport process, a traffic accident occurred on the route. A traffic accident writes a delay of 4 hours in navigation. On the basis of the event, traffic is diverted to alternative routes using the police. Police divert traffic irrespective of material being transported in trucks. The categorization of cargo in this respect is not taken into account and thus endangers human health.

Immediately after the obstacle on the planned route, the operator or dispatcher using the software receives a problem report on the route. This phenomenon is shown in **Figure 6**.

After receiving a crisis situation, the operator receives a solution to the most appropriate solution to the traffic diversion. A diversion to alternative routes is to arrive at point B at an agreed time and to complete an alternative route so as not to pose a threat or other risks in the environment where the means of transport moves with the transport unit. All alternative solutions will alert us to the risks associated with the settings that were set at the input. In case we have marked the height of the means of transport by 3 meters on the routes, this will indicate I risk places in the form of a very small difference in the form of our possibility of limiting or creating another obstacle.

As the input data confirms, they can specify the entire transport process to create the most realistic and acceptable environment possible.
