Many companies seek to understand and optimize scripting with constraints to lower costs and minimize risk. But this is still one of the biggest transport challenges, especially in Brazil.

According to the CNI, the federal highways registered, in 2019, more than 16 thousand accidents involving trucks.

According to specialists, this is mainly due to insufficient and poorly distributed investments. Highways with higher accident rates, therefore more dangerous, receive only 26% of total resources.

With low investments and structures each time more precarious, the broken percorrides passam to present more and more perigo. It is clear, of course, that it is difficult to attend to a country of continental dimensions and frequent moves related to traffic restrictions.

This set of challenges makes manual rotation increasingly inefficient and onerous for companies. But could it be that there is an efficient way of fazer rotation with restrictions?

Or what is roteirização?

Good planning is essential to carry out any freight with excellence. And within this study, factors such as: traffic conditions and lanes used, distance to be covered, toll values, height restrictions and vehicle traffic etc. should be considered.

All this process is called rotation and the process determines what will be the itinerary for the rub, guaranteeing efficiency and speed in the delivery of loads and the necessary security for the drivers of two vehicles.

How does rotation work?

Based on all the orders that need to be delivered, the location of the customers is used to create the most efficient route. This is done considering all service points, while using the shortest (or fastest) route — optimizing the use of fuel, the truck and its components.

Although it seems simple, the scripting consists of several phases, from the creation of an effective policy to the monitoring of vehicles on the streets.

What do we consider restrictions on scripting?

Before we talk about constrained routing solutions, we need to understand what these constraints are and how they impact transportation.

We list below some of the main restrictions faced by companies in between, check this out:

1 – Roads

One of the main challenges of routing with restrictions, as mentioned above, is the Brazilian roads. As transport here depends on the road modal, companies need to face long journeys on unpaved roads, with erosion, dangerous and even in areas of difficult access.

Imagine that, without an efficient routing system, your fleet needs to travel these routes without knowing where the obstacles are. Chances of accidents are much higher, right?

Another restriction that needs to be included in the routing is the speed limits for each path. This information is essential for the estimated time to correspond to reality. Thus, avoiding delays and costs with re-delivery, for example.

2 – Dangerous areas

Unfortunately Brazil is a country with numerous dangerous areas, with little or no security monitoring and with a high probability of theft and robbery. If we manually perform the routing with restrictions, it is not possible to monitor and update the routes to bypass areas that present greater risk considering the type of vehicle and cargo transported.

There are regions, for example, where electronic equipment theft is much higher. Your company can use other means of delivery or perform routing with restrictions using a system that automatically bypasses hazardous areas.

3 – Impossibility of traffic of certain vehicles

Due to the extensive road network, there is a huge variety of obstacles such as bridges, narrower roads or with detours that do not support a vehicle with axles. Not to mention, of course, urban mobility, which is even more restrictive in this regard.

4 – Traffic time restrictions

Recently, legislation changed, in some cities, the traffic permit for large vehicles in some regions, mainly urban ones. In addition to limiting the journey and loading and unloading time, managers still need to be informed about the legislation in force in each stretch of the journey.

Which, of course, makes the whole process even more time-consuming and costly.

5 - Impossibility of unloading in a certain place or time

A large part of urban deliveries are subject to a delivery schedule, mainly in relation to the transport of larger loads, not in the center of large cities.

A roteirização with precise restrictions, therefore, consider that four delivery points have time limiters, to organize or bring them to attend the first ones. Sem, of course, commit to optimization of the course.

How to deal with restrictions?

Two major challenges of rotation with restrictions on volatility. At the end, broken, meanings and norms were altered with much more frequency than we would eat. Turning assim, quase impossível to create a planejamento of manual broken.

Isso you want to say that we are not able to anticipate these restrictions and we need to deal with the many intempere two suits?

No! To your precise company, in truth, to invest in technologies that attend to roteirization with restrictions.

There are ferments that are created to adapt to the needs of your company and system.

Isso wanted to say that these solutions are able to formulate ultra-smart breaks as the use of location dice, which are fed in real time.

Know customer restrictions

It is natural that some customers impose restrictions on the receipt of goods. The most common are the definition of time windows for receipt and refusal to unload if there are products from other customers still in the vehicle.

Knowing these limitations imposed by the audience to be served is crucial to developing an efficient scripting. After all, it's no use choosing the best route if, upon arriving at one of the destinations, the team refuses to pay for being outside the established time, for example.

Group the next stops

Optimizing traffic time between stops allows for greater organization when loading vehicles, taking into account the proximity between destinations. This facilitates the unloading of the goods.

Build a teardrop-shaped script

When performing the route, try to form a path in the shape of a drop on the map, positioning the stops sequentially, making the route more efficient. Also consider stops that have time or collection restrictions. In these cases, it is necessary to evaluate individually to avoid an overlap.

use big vehicles

A good tip to assist in the success of this planning is to use large vehicles, which are capable of attending all the stops on the route. A truck with a large load capacity will reduce operating costs and time to make deliveries.

Try to reconcile deliveries with collections that need to be carried out

These collections are (usually) made after all script deliveries have been completed. However, being able to carry them out throughout deliveries can minimize the distance traveled and avoid overlapping.

But be careful! It must be taken into account that the collected goods will not obstruct those that are scheduled for delivery. If that happens, the most viable solution is to create another itinerary back, as if it were reverse logistics.

So, instead of the truck coming back empty after making all deliveries, it makes the return route passing through all the points that need some collection. This is especially important when, for some reason, it is not possible to form a teardrop-shaped script for making deliveries.

Consider delivering alternative ways

Adopting an alternative means of delivery for stops that are far outside the groupings determined by route planning can be an interesting solution —especially when dealing with smaller volumes.

A good solution for these cases is to use smaller vehicles or even hire a third-party company. By doing these assessments correctly, the cost savings will certainly be real.

Knowledge of operational characteristics

Map the flow of services and demands to determine the performance of this routing. Collect some data such as:

• quantity and frequency of orders;
• restrictions on circulation and stops for loading and unloading;
• limits on working hours;
• pace of product deliveries.

This knowledge is essential for you to be able to plan and execute routines based on the reality of your business and customer demands. Without this, it is difficult to create effective actions —since one would not be aware of important aspects to define the best scripts.
