| Abstract: | One major problem of GPS equipped probe vehicle traffic information collection is how to determine probe vehicle sample sizes. Based on requirements of different traffic parameters measurements,methods of determining probe vehicle sample sizes are analyzed. Considering the precision of positioning and efficiency of correspondence, a calculative model is given and it has an important application value. |
