There is a need to design a road so as a good slope is achieved on the road channel. If the longitudinal grade of the roadway is too flat (usually 0.5%)  the channel also will be flat and the same grade.

Having flat channels will cause the water to pond or move very slowly. That will cause issues for the vehicles using the road way. More pits will need to be introduced to capture the water so that the road will not flood.

In the photograph above there is evidence that the Kerb and channel would have flat grades. The water marks and ponding is an indicator that you might have a flat channel.

As it is not practical to redo the road again, additional drainage will be needed.

Open drains can carry a lot of stormwater. They are designed to capture water overland and also pipes can discharge water to them.

The open drain is to have sufficient cross-sectional area to take all flows. In general terms they should be designed to 1% Annual Exceedence Probability (AEP) and consideration be given where the water will go if the capacity is exceeded.

The slope of the channel should be steep enough to carry water without water ponding and the side slopes should be not too steep so they can be easily maintained.
