A main component of an Intelligent Transport System (ITS) is the navigation system to be used in the 'intelligent' vehicle. In fact, driving a vehicle is a complex task as the driver has to control the vehicle as well as make decisions about getting to his/her destination. Too much information on the map (i.e. a complex map) would confuse the driver, while too little information would not be sufficient for the user to compare with the actual environment. Sufficient information but poorly presented would also result in confusion. This paper reports on a study of the design of dynamic maps for land vehicle navigation through an investigation of different designs with different levels of information contents and visual effects using various dynamic variables. Different colours were assigned to the road and building names according to the position of the vehicle, and blinking symbols were used to indicate direction restrictions. Also, a set of maps with different degrees of complexity was designed such that the users would be provided with different levels of contents and representation by zooming in and out. The effectiveness of the design was investigated in the map evaluation process.
