Traffic control method for relieving vehicle congestion on parallel roads

A method of controlling traffic of vehicles running on each of a plurality of parallel running roads, each of said roads being connected at points positioned at an interval of a predetermined distance, and at least one of said plurality of roads having a plurality of lanes, said method comprising the steps of:

• detecting traffic of vehicles running in two counter directions on each of said plurality of roads;
• and
• changing a ratio of the number of lanes assigned to a particular direction of at least one of said plurality of roads, in accordance with said detected traffic of vehicles running in the two counter directions.

A method of controlling traffic of vehicles running on both of first and second parallel running roads, both of said first and second roads being connected at points positioned at an interval of a predetermined distance, and at least one of said first and second roads having a plurality of lanes, said method comprising the steps of:

• detecting traffic of vehicles running in two counter directions on each of said first and second roads, at a position before a connecting point of each of said first and second roads;
• and
• changing a ratio of the number of lanes assigned to a particular direction of at least one of said first and second roads, in accordance with said detected traffic of vehicles running in the two counter directions.

A method of controlling traffic of vehicles running on each of plurality of parallel running roads, each of said roads being connected at a point positioned at an interval of a predetermined distance, and a plurality of intersections with traffic lights being installed on each of said roads at intervals of the predetermined distance, said method comprising the steps of:

• detecting traffic of vehicles running in two counter directions on each of said roads, at a position before at least one connecting point of each of said plurality of roads;
• and
• controlling an offset parameter of a plurality of traffic lights on each of said roads, in accordance with said detected traffic of vehicles running in the two counter directions.
