Year 11 pupil Logan Stadnyk collected data on traffic using Gordon and Factory Rds as part of a geography class project.
The data was collected by pupils for three half-hour periods on the two roads, in the morning, afternoon and night.
More than 2000 vehicles were recorded in the traffic data.
Logan (16) told the board members about traffic problems in Mosgiel and challenged the board to seek solutions.
The number of big trucks, several with trailers, travelling on Gordon Rd between 7.45am and 8.15am was a problem, he said.
For the project, pupils counted traffic from both sides of Gordon Rd, outside Blackstone Cafe and the post office.
In a morning session, about 20 trucks used the stretch of road.
In the afternoon about 10 trucks were counted and at night about six trucks were logged.
Logan said traffic often got congested on Gordon Rd and many vehicles had only one person inside.
''People in Mosgiel aren't using their transport effectively,'' Logan said.
The public buses they saw never had more than five passengers, he said.
''People aren't using them - perhaps that's something for the board to think about as to how effectively we use the buses.''
One cyclist could generally be seen using a cycle lane at any time of the day, Logan said.
Dunedin City Council transport safety team leader Hjarne Poulsen, who was at the meeting, said Logan's data was accurate and the vehicle occupancy information would be ''handy''.
''Well done,'' he told Logan.
The council was aware of the congestion on Gordon Rd but it was also State Highway 87 so it was the responsibility of the NZ Transport Agency.
''We have been working with them for the last couple of years to try and work out what could be done with the signalised intersections. A lot of it has to do with efficiency versus safety - safety is the most important.''
Heavy traffic was allowed to travel on Gordon Rd and there was no heavy traffic bypass to avoid Mosgiel's main street.
Logan suggested a heavy traffic bypass on Riccarton Rd.
''Having heavy vehicles on Gordon Rd, which is a centre for commerce in Mosgiel, is not a very good idea and could potentially be dangerous,'' Logan said.
Mr Poulsen said the council wanted more people to use public buses and cycleways and added more education on the benefits of cycling was needed.
''It's a matter of educating people and getting more cycle lanes out there and getting people into [them],'' Mr Poulsen said.
Cr Kate Wilson moved the incoming board consider following up with the college and council to investigate the questions Logan's research posed and all the board members were in favour.
