Abstract
Abstract A system for controlling the direction of traffic flow in different lanes of a multiple lane road. The lanes of the road are separated by strips selectively illuminated by one or two rows of tubular type light sources which provide either two substantially solid illuminated lines indicating that traffic from adjacent lanes should not cross the strip to an adjacent lane, or which provide a single broken illuminated line to indicate that traffic may cross such a divider strip to an adjacent lane.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
161 words
In a system for controlling the direction of traffic flow in different lanes of a multiple lane road, the combination of means positioned in the road bed dividing the road into a plurality of lanes, each of said dividing means comprising two rows of lightemitting members positioned in said road bed and arranged to be visible to an operator of a motor vehicle proceeding over said road, a source of electric current energizing said light-emitting members, and means selectively connecting said source of electric current to said light-emitting members in each of said dividing means so that light emitted from members in a selected one of said dividing means forms a substantially continuous luminous double line when said connecting means is in a predetermined position to designate the dividing means separating traffic traveling in opposite directions, and selected ones of said light-emitting members in the others of said dividing means being connected by said connecting means to produce broken luminous lines.
Claim 2
Dependent Claim
161 words
In a system for controlling the direction of traffic flow in different lanes of a multiple lane road, the combination of means positioned in the road bed dividing the road into a plurality of lanes, each of said dividing means comprising two rows of lightemitting members positioned in said road bed and arranged to be visible to an operator of a motor vehicle proceeding over said road, a source of electric current energizing said light-emitting members, and means selectively connecting said source of electric current to said light-emitting members in each of said dividing means so that light emitted from members in a selected one of said dividing means forms a substantially continuous luminous double line when said connecting means is in a predetermined position to designate the dividing means separating traffic traveling in opposite directions, and selected ones of said light-emitting members in the others of said dividing means being connected by said connecting means to produce broken luminous lines.
Claim 3
Dependent Claim
50 words
In a system for controlling the direction of traffic flow in different lanes of a multiple lane road, the combination as set forth in claim 1, further characterized in that said light-emitting members comprise a plurality of elongated tubular light sources adapted to be arranged end-to-end in said dividing means.
Claim 4
Dependent Claim
42 words
In a system for controlling the direction of traffic flow in different lanes of a multiple lane road, the combination as set forth in claim 2, further characterized in that said light sources are positioned in channels formed in said road bed.
Claim 5
Dependent Claim
38 words
In a system for controlling the direction of traffic flow in different lanes of a multiple lane road, the combination as set forth in claim 3, further characterized in that said channels are provided with tRanslucent cover means.
Claim 6
Dependent Claim
54 words
In a system for controlling the direction of traffic flow in different lanes of a multiple lane road, the combination as set forth in claim 1, further characterized in that said selective connecting means comprises manually controlled switches located in an observation tower from which a predetermined section of said road may be observed.
Claim 7
Dependent Claim
84 words
In a system for controlling the direction of traffic flow in different lanes of a multiple lane road, the combination as set forth in claim 2, further characterized in that said plurality of elongated tubular light sources are arranged in two rows in each of said land dividing means and said light sources in one of said rows and alternate ones of said light sources in the other of said rows are connected in parallel to said electric current source by said connecting means.
