Traffic Counting

Traffic counting is used in combination with the p-trak in monitoring pollution hot spots in Long Beach. Pollution hotspots are identified by a-team members going out to the community and mapping these areas. These locations are designated for traffic counting and p-trak monitoring data collection which has been the focus for the a-team's work.  Traffic counting allows individuals to see the overall impact local traffic is having on their community. A-team members focus on counting semi-trucks and other diesel emitting vehicles. In selecting an area to do traffic counting, a-team members ask a few questions before selecting a target area such as: Approximately how many diesel trucks travel down the street during a given time? How close is the street to any homes, parks, schools, community center? Has there ever been any traffic data collected in this area? Are there any major warehouses, ports, rail-yards, industrial zones and how do they impact the traffic in your area? Is is safe to conduct traffic counting in this location?

Particulate Matter Monitoring (P-Trak)

The p-trak is a device which measures ultra fine particles markers for traffic exhaust. These particles travel through the air people breathe. The smaller the particles are, the further they travel into the respiratory system and  the bloodstream and our body's organs. Particles are measured by the p-trak in particles per cubic centimeter. Although this device does not measure total particulate matter or other pollutants it is highly useful in monitoring a hotspot area. A-team members use the p-trak along with traffic counting to monitor different areas in Long Beach that are highly impacted by pollution, such as near freeways, rail yards and major road arteries. Today, LBACA's A-team has focused its monitoring on locations near schools.
