- G08G 1/0145: {for active traffic flow control}
- G08G 1/096775: {where the origin of the information is a central station}
- G08G: TRAFFIC CONTROL SYSTEMS (guiding railway traffic, ensuring the safety of railway traffic B61L; arrangement of road signs or traffic signals E01F9/00; radar or analogous systems, sonar systems, lidar systems specially adapted for traffic control G01S13/91, G01S15/88, G01S17/88; {radar or analogous systems, sonar systems, lidar systems specially adapted for anti-collision purposes G01S13/93, G01S15/93, G01S17/93})

## Abstract

A computer-implemented dynamic road stretch dividing method, the method comprising: determining a current lane distribution of partitions of a road stretch; calculating a new lane distribution of the road stretch to ameliorate traffic based on a pragmatic factor; changing an alignment of the partitions of the current lane distribution to obtain the new lane distribution; and updating the pragmatic factor based on at least one of an external policy and a constraint input by a user.

## Claims

### Claim 1

A computer-implemented dynamic road stretch dividing method, the method comprising:
determining a current lane distribution of partitions of a road stretch;
calculating a new lane distribution of the road stretch to ameliorate traffic based on a pragmatic factor,
changing an alignment of the partitions of the current lane distribution to obtain the new lane distribution; and
updating the pragmatic factor based on at least one of an external policy and a constraint input by a user.

### Claim 2

A computer program product for dynamic road stretch dividing, the computer program product comprising a computer-readable storage medium having program instructions embodied therewith, the program instructions executable by a computer to cause the computer to perform:
determining a current lane distribution of partitions of a road stretch;
calculating a new lane distribution of the road stretch to ameliorate traffic based on a pragmatic factor,
changing an alignment of the partitions of the current lane distribution to obtain the new lane distribution; and
updating the pragmatic factor based on at least one of an external policy and a constraint input by a user.

### Claim 3

A dynamic road stretch dividing system, said system comprising:
a processor, and
a memory, the memory storing instructions to cause the processor to perform:
determining a current lane distribution of partitions of a road stretch;
calculating a new lane distribution of the road stretch to ameliorate traffic based on a pragmatic factor,
changing an alignment of the partitions of the current lane distribution to obtain the new lane distribution; and
updating the pragmatic factor based on at least one of an external policy and a constraint input by a user.
