TABLE 11 - 2001 NPTS: Distribution of the Relative Deviations of Reported to STPD Estimates by Distance

20,700 car passenger and driver trips below 100 km

STPD (km)	Share of trips with relative deviations of reported to SDPD estimates (%)
STPD (km)	Within the measuring uncertainty	<5	5-10	10-25	25-50	≥50	Total
0-9	28.2	8.7	8.2	19.5	19.1	16.3	100.0
10-19	17.1	15.9	13.2	23.8	15.9	14.1	100.0
20-29	12.6	18.0	18.1	26.4	14.1	10.7	100.0
30-39	13.4	24.3	14.8	22.6	12.1	12.8	100.0
40-49	9.5	23.9	27.6	22.1	5.5	11.3	100.0
≥50	7.1	25.5	18.4	24.1	9.4	15.5	100.0
Total	23.6	12.0	10.7	21.1	17.4	15.3	100.0

Key: SDPD = shortest distance path distance; STPD = shortest time path distance.

Note: Rows may not add to 100.0 because of rounding.
