Planning Routes with Conditional Road Restrictions

by Rhocela Pasigna

Alleviating traffic through road policies In the early 1970s, Argentina enforced a city-wide road entry policy to regulate the number of vehicles that enter its capital, Buenos Aires. The policy was an odd-or-even rule based on the plate number of vehicles.

In Asia today, several countries such as Indonesia and the Philippines have implemented similar road restrictions based on various factors such as plate number, vehicle type and color, and time of day.

Impacts in logistics While these regulations help ease urban traffic, it poses hard limitations especially to businesses in the logistics space. For example, planning delivery routes has become more complex due to the added constraints in the type of vehicle to use, sanctioned time and day, and so on.

When planning routes, taking these regulations into account is critical. Discounting these aspects of the traffic only produces inefficient results and unrealistic estimations. This can domino effect into multiple problems: increased exceptions on the ground, late or cancelled deliveries, unsatisfied customers, increased customer service calls, and a drop in the overall performance and productivity.

Despite the various technologies that exist today, many businesses are yet to find a solution that directly addresses this problem. If such solutions exist, they would be owned by major enterprises as a proprietary software, and not as a service offered in the market.

Zyllem’s solution: A planning algorithm that honors conditional road restrictions

After listening to our customers and understanding the real need to address this gap, we have enhanced our platform to support road restriction frameworks.

Zyllem’s Planning Module now honors government-imposed road regulations by assigning tasks only to vehicles that are allowed to travel on a road at a certain instance. This, on top of SLAs, delivery windows, working hours, and all other factors that are considered by the route optimization algorithm. These regulations are incorporated into the algorithm based on your country. The feature allows you to define your own vehicle profiles and set rules based on these profiles, as well as time and days.

As a preview of this feature, below is the Traffic Coding Scheme of Metro Manila.

And here is a route planned by Zyllem. The route is scheduled on a Thursday. Based on Metro Manila's traffic coding scheme, vehicle numbers 7-8 are restricted on these days. Accordingly, the system did not assign any routes for these vehicles.

If you happen to be using or evaluating route planning technologies today, you may find that this ability to incorporate country-based road regulations is unique to Zyllem. This feature has been a game changer for our customers. The advantage of having realistic ETAs alone changes the game: less exceptions on the ground, predictable delivery windows, on-time deliveries, satisfied customers, and increased performance and productivity.

Zyllem can apply road restriction frameworks of any country. Want to see more of this feature? Schedule a demo or contact
