Why is truck navigation different? § Truck navigation knows about truck restrictions - Legal restrictions - Physical restrictions - Warnings § 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 3 rd Partner meeting, 17. -19. 03. 2010, Berlin 2

Individual interests vs. communal interests Individual interest Communal interest § Optimizing personal time/distance § Protecting sensible city areas § Thinking in street capacities and traffic emmissions 3 rd Partner meeting, 17. -19. 03. 2010, Berlin 3

Project aims § 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 § 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 3 rd Partner meeting, 17. -19. 03. 2010, Berlin 4

Routing algorithms § 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 methods Prefer and avoid – a bonus/malus system § 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. 3 rd Partner meeting, 17. -19. 03. 2010, Berlin 5

Modelling the routing network § Collect data (routes, POI, truck restrictions) § 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 3 rd Partner meeting, 17. -19. 03. 2010, Berlin 6

The objectives for the route 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 3 rd Partner meeting, 17. -19. 03. 2010, Berlin 7

The recognized problems § Bridging (Not preferred roads that would connect preferred routes) are highly attractive § 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 3 rd Partner meeting, 17. -19. 03. 2010, Berlin 8

Recognized systematics / methods to solve the problems § Boni should only be applied up to 40%, on motorways up to 80% § 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 3 rd Partner meeting, 17. -19. 03. 2010, Berlin 9

Bringing preferred truck routes to reality § Communities and Organisations have to team-up internationally for promoting the necessity of preferred truck routing § 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. 3 rd Partner meeting, 17. -19. 03. 2010, Berlin 18
