Navigation System and Method
First Claim
1. A navigation system comprising:
- a memory in which information concerning road sections and information concerning time-dependent traffic restrictions are stored such that, in each case, information concerning time-dependent traffic restrictions is assigned to road sections; and
a route computation processor operatively configured such thatwhen computing a route, the memory is accessed in order to compute the route based on information concerning road sections and based on information concerning time-dependent traffic restrictions, andwhen computing the route, information concerning time-dependent traffic restrictions for a first portion of the road sections, to which information concerning a time-dependent traffic restriction is assigned, is taken into account and, information concerning time-dependent traffic restrictions for a second portion of the road sections, to which information concerning a time-dependent traffic restriction is assigned, is not taken into account.

Abstract
A navigation system includes a memory in which information concerning road sections and information concerning time-dependent traffic restrictions are stored such that time-dependent traffic restrictions are assigned to a portion of the road sections. A route computation process is set up such that, when computing a route, the memory is accessed in order to compute a route based on information concerning road sections and based on information concerning time-dependent traffic restrictions. When computing the route, information concerning time-dependent traffic restrictions for a first portion of the road sections, to which information concerning a time-dependent traffic restriction is assigned, is taken into account and, information concerning time-dependent traffic restrictions for a second portion of the road sections, to which information concerning a time-dependent traffic restriction is assigned, is not taken into account.

10. A method of operating a navigation system having a memory for storing information concerning road sections and information concerning time-dependent traffic restrictions assigned to said road sections, the method comprising the acts of:
-
accessing the memory when computing a route in order to compute the route based on the information concerning road sections and the information concerning time-dependent traffic restrictions; taking into account, when computing the route, the information concerning time-dependent traffic restrictions for a first portion of the road sections to which the information concerning time-dependent traffic restrictions is assigned; and not taking into account, when computing the route, the information concerning the time-dependent traffic restrictions for a second portion of the road sections to which the information concerning the time-dependent traffic restrictions is assigned. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
