The traffic count data for the flow map is obtained by the use of mechanical traffic counters placed on the street, within the same area as the count station, for a 24-hour period during a typical weekday.
Limitations of Data
The information contained in this map represents a weekday average daily traffic volume. Weekends and holiday counts are not included in the averages. Through the averaging process, the seasonal fluctuation of traffic volume is not apparent, but recognition of this condition should be made for proper perspective.
