Typical Examples of Lane Balances. Please use your own words to describe the principles for the balance in the number of lanes based on the following Exhibit. DIVERGING MERGING -2 3 -4 2 2

Answer 1

The balance in the number of lanes can be assessed using the following principles

At entrances, the number of lanes beyond the merging streams must be at least the sum of the lanes on the merging roadways less one.

At exits, the number of approach lanes on the carriageway must equal the number of lanes on the carriageway beyond the exit plus the number of lanes on the exit, less one.

The travelled way of the carriageway must not be reduced by more than one lane at a time.
