Preferred truck routes meet navigation

Michael HubschneiderPTV AG

23rd Partner meeting, 17.-19.03.2010, Berlin

Truck navigation knows about truck restrictions- Legal restrictions

- Physical restrictions

- Warnings

Why is truck navigation different?

Truck navigation has different requirements for routes- Avoiding U-turns

- Avoiding residential areas

- Avoiding smaller streets

- Access to restricted areas

Truck navigation integration- Needs a programmable interface

- Can be applied with different systems and hardware


Individual interest Optimizing personal time/distance

Individual interests vs. communal interests

Communal interest Protecting sensible city areas

Thinking in street capacities and traffic emmissions


Develop algorithmsroutes for integration into a navigation system for truck preferred routing

Modelling a routing network for trucks on desktop routing software, that fits both communal needs and trucker needs

Project aims

Develop a system how the learned mechanisms can be transferred to other towns

Transfer the preferred routing network to the navigation system, building the first navigation system that is able to prefer communal truck routes


Keep it simple and stupid (KISS)It has to be very simple to be integrated by any navigation systems developer

Works like the brain with two simple methodsPrefer and avoid – a bonus/malus system

Routing algorithms

Preferred road segments get a bonus,road segments that should be avoided get a malus

Bonus / malus have different strengths

Like in the brain – the location decides on the effect.


Collect data (routes, POI, truck restrictions)

Modelling the routing network

Define test routes- Routes targeting industrial zones

- Routes crossing the town

- Intercommunal routes

Model test

Improve the model (adding bonus/malus to segments)

Recognize and summarize the systematics behind the model


Trucks shall use the defined preferred routes when driving to industrial areas from the motorway

Truck routes crossing the town center are not wanted, it is better to use more motorways

Avoid routes that are charged by high emmissions / traffic

But don‘t generate too high detours, routes still have to be reasonable

The objectives for the route model


Bridging (Not preferred roads that would connect preferred routes) are highly attractive

The recognized problems

Accessability to all parts of an industrial area through one entry

Avoiding areas (like city centers)

Avoiding congested or high emmission areas

Systematical problems

Avoiding certain road which tend to lead routes through narrow streets around the area (traffic evasion)

Influencing the system too strongly leads to too many detours


Boni should only be applied up to 40%, on motorways up to 80%

Recognized systematics / methods to solve the problems

Mali should only be applied cautiously, only in special situations, else it can lead to traffic evasion

Mali make sense for avoiding areas like city centers

Sometimes mali make sense on bottlenecks like bridges

Check with test sets with focus on- Taking the desired roads

- Time/distance effects

- Integrate local experts and stakeholders

Real live examples (1/7)














Communities and Organisations have to team-up internationally for promoting the necessity of preferred truck routing

Bringing preferred truck routes to reality

Solutions to easily create preferred route models through the web are needed, using the same systematics

The preferred routes have to be collected in open databases

Map manufacturers have to use the data and provide it for the navigation system providers

Navigation system providers bring it to the mass market.
