Apparatus for surveying and marking highways

An apparatus for surveying and marking highways comprising:

• a computer for installation in a vehicle;
• a storage device connected to said computer;
• a first transducer means connected to said computer for sensing increments of distance travelled along a highway by a first vehicle and generating a first distance signal representing the increments of distance to said computer, said computer being responsive to said first distance signal and a second distance signal for generating a difference signal representing the spacing between the first vehicle and a second vehicle;
• a pavemaking application module including a first radio modem connected to said computer, a first radio transmitter connected between said modem and a first antenna for generating said distance signal as a first radio signal, a pulse decoder connected to said computer, a first radio receiver connected between said pulse decoder and a second antenna for receiving a second radio signal and generating said second distance signal to said computer, a display means for installation in the second vehicle, a second radio modem connected to said display means, a second radio receiver connected between said second radio modem and a third antenna for receiving said first radio signal and generating said distance signal to said display means, a second transducer means for sensing increments of distance travelled by the second vehicle and generating said second distance signal, a pulse encoder connected to said second transducer means, and a second radio transmitter connected between said pulse encoder and a fourth antenna and responsive to said second distance signal for generating said second radio signal whereby said display means indicates the spacing between the first and second vehicles;
• and
• a least one application module means connected to said computer for sensing a parameter of the highway other than increments of distance and generating a detector signal representing the parameter sensed to said computer, said computer being response to said first distance signal and said detector signal for generating a highway data signal referencing said detector signal to said first distance signal and storing said highway data signal in said storage device.
