This was the sum of traffic counts on all road segments within 100 m, multiplied by the length of each road segment.
Correlations between background BS and traffic intensity on the nearest road and sum of traffic intensity in a 100 m buffer were modest: 0.12 and 0.28, respectively.
For example, we were unable to construct a metric for traffic density (sum of traffic on all roads within a buffer) because the CalTrans AADT data is reported for road segments, not complete roads.
These data indicate that although ICAM-1 is upregulated on brain endothelium under ischemic conditions in vitro and in vivo, ischemia/reperfusion fails to induce the sum of traffic signals in brain endothelial cells required to promote PMN transmigration across the endothelial monolayer.
Science
30 31 In addition to concentrations of pollutants, we considered two traffic variables at the participant's residence: traffic intensity on the nearest road (vehicles/day) and traffic load on major roads in a 100 m buffer (vehicles×m/day), defined as the sum of traffic intensity on roads with >5000 vehicles/day multiplied by the length of those roads in a 100 m buffer.
Science
For each address, we calculated the traffic intensity at the nearest street and the traffic load (sum of traffic intensity multiplied by length of road segment in all segments) in a 100 m buffer and derived 10-year average values for each participant.

As indicated in [17], the traffic load TL i in each sensor node (say node i) is defined as the sum of the traffic passing through node i and the traffic passing through node i's neighbor nodes due to the broadcast nature of radio channels.
The traffic density at each residential location was the sum of the traffic density from contributing roadway segments.
Accounts for the sum of the traffic or connections of all users of the network at a given time.
The average cost of browsing in each country was then multiplied by the amount of traffic generated in each country, and the resulting totals were summed and compared to the totals for uncompressed data traffic.

Expert writing Tips
Best practice
When using "sum of traffic" in scientific writing, clearly define the area or time period to which the sum refers (e.g., "sum of traffic within a 100-meter radius").
Common error
Avoid using "sum of traffic" without specifying the parameters for summation. For example, failing to mention whether it's a daily, weekly, or annual sum can lead to misinterpretations.

Ludwig's WRAP-UP
The phrase "sum of traffic" is a grammatically sound and usable expression, as confirmed by Ludwig. It's frequently found in scientific contexts related to environmental health and network analysis, where it serves to quantify traffic volume or intensity. While examples are limited, it's clear that the phrase is best used when specific parameters for summation (area, time) are clearly defined. Alternatives such as "total traffic volume" or "aggregate traffic flow" may be considered for a more formal tone. Ludwig's examples underscore its role in defining quantifiable metrics in research and planning, reinforcing its value in precise communication.
