 this query a second map such as that shown in FIG. 2 is generated. As can be seen from FIG. 2, various branches of a road network radiating from an intersection, designated as A-F in FIG. 2, can be identified. To improve the usefulness of the display, a background map, such as a road map, may be displayed underlying the displays of any of FIGS. 1, 2 or 4 (described infra).
In the event that additional information relating to the delay is desired, further queries can be made. For example, vehicles which are traveling toward the intersection can be requested to broadcast in a slot which corresponds to the slot they are in and to their velocity toward the intersection. This allows for generation of the graph shown in the lower portion of FIG. 3. Additional slots may be used for the acquisition of other information regarding the responding vehicles. Such information may also be graphed as shown in the upper portion of FIG. 3.
Alternatively or additionally, a map which shows the average velocity of the vehicles toward the intersection as a function of the position can be generated. Such a map is shown in FIG. 4. To acquire the information needed for generating such a map, a number of queries maybe made, each requesting an indication from all vehicles within the area of interest having a given average velocity toward the intersection. The responding vehicles would broadcast their indication signals in slots corresponding to their position. In the map of FIG. 4, the velocity for a given pixel is determined, for example, as the average velocity of the reporting slots for that position. In a display of the map of FIG. 4, the velocity or delay toward the intersection can, for example, be displayed as a gray scale value or as a color, with for example red being the highest velocity or delay and blue being a minimum displayed velocity or delay.
FIG. 5, is a generalized block diagram for a system useful for performing the ITS function described above (and which is also useful for the method of the present invention). FIG. 5 shows a base station or control center 91 having a control center transmitter 79 which broadcasts queries and optionally other signals to vehicles on command from a control computer 80. A remote vehicle 85 (only one vehicle is shown for simplicity) receives the query at a vehicle receiver 84 and transmits commands to a microprocessor 86, based on the queries it receives from the control center.
Microprocessor 86 also receives information regarding the status of the vehicle from one or more information generators and sensors indicated by reference numeral 88. This

As can be see from FIG. 2, diverse branches of a road network radiating from an overlap, designated as A - F in FIG. 2, can be identified. To better the usefulness of the display, a background function, such as a road function, may be displayed underlying the display of any of FIGS. 1, 2 or 4 (described infra). 
 In the event that additional data relating to the delay is desired, further question can be made. For case, vehicle which are traveling toward the intersection can be requested to circulate in a slot which corresponds to the slot they are in and to their velocity toward the overlap. This allows for genesis of the graph shown in the lower portion of FIG. 3. extra slots may be used for the acquisition of other information regarding the respond vehicles. Such information may also be graphed as shown in the upper portion of FIG. 3.

The respond vehicles would air their indication signals in slots corresponding to their position. In the function of FIG. 4, the velocity for a given pixel is determined, for example, as the average velocity of the reporting slots for that position. In a display of the function of FIG. 4, the velocity or delay toward the intersection can, for example, be displayed as a grey scale value or as a semblance, with for example crimson being the highest speed or delay and blue being a minimum displayed velocity or delay.
