Preferred truck routes meet navigation Michael HubschneiderPTV AG
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 3rd Partner meeting, 17.-19.03.2010, Berlin
Individual interests vs. communal interests Individual interest • Optimizing personal time/distance Communalinterest • Protecting sensible cityareas • Thinking in streetcapacitiesandtrafficemmissions 3rd Partner meeting, 17.-19.03.2010, Berlin
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 systemhowthelearnedmechanismscanbetransferredtoothertowns • Transfer thepreferredroutingnetworktothe navigation system, buildingthefirst navigation systemthatisabletoprefercommunal truck routes 3rd Partner meeting, 17.-19.03.2010, Berlin
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 methodsPrefer and avoid – a bonus/malus system • Preferredroadsegmentsget a bonus,roadsegmentsthatshouldbeavoidedget a malus • Bonus / malus have different strengths • Like in thebrain – thelocationdecides on theeffect. 3rd Partner meeting, 17.-19.03.2010, Berlin
Modelling the routing network • Collect data (routes, POI, truck restrictions) • Definetestroutes • Routestargetingindustrialzones • Routescrossingthetown • Intercommunalroutes • Model test • Improvethe model (addingbonus/malus tosegments) • Recognizeandsummarizethesystematicsbehindthe model 3rd Partner meeting, 17.-19.03.2010, Berlin
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 3rd Partner meeting, 17.-19.03.2010, Berlin
The recognized problems • Bridging (Not preferred roads that would connect preferred routes) are highly attractive • Accessabilityto all partsof an industrialareathroughoneentry • Avoidingareas (likecitycenters) • Avoidingcongestedorhighemmissionareas Systematicalproblems • Avoidingcertainroadwhichtendtoleadroutesthroughnarrowstreetsaroundthearea (trafficevasion) • Influencingthesystemtoostronglyleadstotoomanydetours 3rd Partner meeting, 17.-19.03.2010, Berlin
Recognized systematics / methods to solve the problems • Boni should only be applied up to 40%, on motorways up to 80% • Mali shouldonlybeappliedcautiously, only in specialsituations, elseitcanleadtotrafficevasion • Mali make sense foravoidingareaslikecitycenters • Sometimesmalimake sense on bottleneckslikebridges • Check withtestsetswithfocus on • Takingthedesiredroads • Time/distanceeffects • Integratelocalexpertsandstakeholders 3rd Partner meeting, 17.-19.03.2010, Berlin

Bringing preferred truck routes to reality • Communities and Organisations have to team-up internationally for promoting the necessity of preferred truck routing • Solutions toeasilycreatepreferred route modelsthroughthe web areneeded, usingthe same systematics • The preferredrouteshavetobecollected in open databases • Map manufacturershavetousethedataandprovideitforthe navigation systemproviders • Navigation systemproviders bring ittothemassmarket. 3rd Partner meeting, 17.-19.03.2010, Berlin
