## Abstract

An environmental assessment system for correlating environmental data with traffic data having, a traffic/environment system including a) a traffic count system for obtaining the traffic data of moving objects on a road, and classifying the moving objects into several vehicle types, b) an environmental sensor system including a particulate matter (PM) sensor for measuring PM concentration and/or a carbon dioxide (CO2) concentration sensor, c) a microphone for obtaining sound signals originated from the moving objects on the road, d) a communication device and e) a microcomputer/memory for running computer programs, the computer programs including a function for adding a time stamp showing a time onto the traffic data, and a sever having functions for correlating the traffic data with the environmental data, wherein the traffic count system is arranged to classify the traffic data by referring to the sound signals obtained by the microphone.

## Claims

### Claim 1

An environment assessment system for correlating environmental data with traffic data comprising:
a traffic/environment system comprising:
a) a traffic count system for obtaining the traffic data, the traffic count system including an image sensor for counting a number of moving objects on a road, and classifying the moving objects into vehicle types;
b) an environmental sensor system including a particulate matter (PM) sensor for measuring PM concentration emitted from the moving objects and/or a carbon dioxide (CO2) concentration sensor for measuring carbon oxide concentration included in air originated from the moving objects;
c) a microphone for obtaining sound signals originated from the moving objects on the road;
d) a communication device for transmitting and receiving the traffic data and the environmental data between other traffic/environment systems and other devices via a network linked thereof; and
e) a microcomputer/memory for running computer programs, the computer programs including a function for adding a time stamp showing a time onto the traffic data when the traffic data is obtained, and
a server having functions for correlating the traffic data with the environmental data transmitted from the traffic/environment system via the network,
wherein the traffic count system is arranged to classify the traffic data by referring to the sound signals obtained by the microphone, and
wherein the computer programs include a function for identifying a moving object, which cannot be captured by the image sensor, by utilizing the obtained sound signals.

### Claim 2 (depends on 1)

The environment assessment system for correlating environmental data with traffic data of claim 1,
wherein the environment sensor system includes a PM sensor for measuring the PM concentration of any one of PM 1.0, 2.5, 4.0, 10, or any combination thereof.

### Claim 3 (depends on 1)

The environment assessment system for correlating environmental data with traffic data of claim 1,
wherein the computer programs include a function for identifying the moving object by utilizing specific sound signals or specific frequency ranges which have been obtained by a pre-learning carried out before classifying the traffic data.

### Claim 4 (depends on 1)

The environment assessment system for correlating environmental data with traffic data of claim 1,
wherein the computer programs include a function for classifying the moving objects including the same body shape having different engine types.

### Claim 5 (depends on 1)

The environment assessment system for correlating environmental data with traffic data of claim 1,
wherein a unique sensor identification (SID) is assigned to the sensor system.

### Claim 6 (depends on 1)

The environment assessment system for correlating environmental data with traffic data of claim 1,
the server has a function for obtaining a correlation coefficient between the traffic data and environmental data.

### Claim 7 (depends on 6)

The environment assessment system for correlating environmental data with traffic data of claim 6,
wherein the traffic data and the environmental data have different timestamps by referring to a travel time of air including the environmental data from the moving object emitted the environmental data to a point where the traffic count system is installed.

### Claim 8 (depends on 1)

The environment assessment system for correlating environmental data with traffic data of claim 1,
wherein the computer programs include a function for giving the same identification code onto two moving objects when two traffic/environmental systems identify that the moving objects passing by two observation points where the traffic/environment system is installed are the same.

### Claim 9 (depends on 8)

The environment assessment system for correlating environmental data with traffic data of claim 8,
wherein the same identification code is kept in the server in a certain limited time.

### Claim 10 (depends on 9)

The environment assessment system for correlating environmental data with traffic data of claim 9,
wherein the certain limited time is determined based on a moving time of the moving objects between two points where the traffic/environment system is installed.
