Abstract:
1. A navigation device having a function of computing a recommended speed of a moving object, said navigation device comprising: a traveling route estimating unit for estimating a route along which said moving object will travel and which falls within a predetermined region from a current position; a first recommended speed arithmetic unit for computing a recommended speed in each of road sections on the route estimated by said traveling route estimating unit on a basis of road state information showing a road state; a second recommended speed arithmetic unit for computing a recommended speed in a road section between said road sections for each of which the recommended speed is computed by said first recommended speed arithmetic unit according to a predetermined speed variation function; and a parameter setting unit for storing parameters defining operational characteristics of said moving object according to types of moving objects including said moving object, wherein said second recommended speed arithmetic unit determines the speed variation function for defining acceleration and deceleration according to the operational characteristics of said moving object by using a parameter which said second recommended speed arithmetic unit selects on a basis of the type of said moving object from among the parameters stored in said parameter setting unit, and computes the recommended speed in the road section between said road sections for which the recommended speed is computed by said first recommended speed arithmetic unit according to said speed variation function.
