A very tricky question : I wanna use a broken centerline on most parts of my roads and streets, a double line only in some curves. But I cannot find the rules used 1965, only from todays, and as I saw there were many revisions. Which colour should I use, yellow or white ? I am afraid that yellow will not be very visible on a grey or black background. And what should be the respective lengths of "marks" and "spaces" ? Thanks for any answer from a modeller in USA who still remembers such things ...  |

Even up to today, white dash lines, OK to pass/cross. Yellow pass/cross with caution. Solid white varies but generally don’t pass/cross (although OK some states (the thick/wider white is do not cross/pass and typically at intersections, gore points (on/off ramps) and crosswalks.
I have no problems with white paint pens on black paints but yellow oil pens completely disappear as does the red mostly. I had to find ‘Pastel’ pens for these colors. Otherwise, many print shops can print large areas so you could CAD up all and save as a PDF and voila.

By the mid-60s most states were changing over to federal standards such as: mutcd.fhwa.dot.gov/services/publications/fhwaop02090/#:~:text=Pavement%20markings%20are%20also%20used%20to%20alert%20users,across%20a%20lane%20indicates%20a%20speed%20hump%20ahead. But prior to that every state had their own way of marking a road. The lines all white about 3-4 inches wide. The “broken line” was 8-10 feet in length and spaced 3-4 feet apart. The “solid white line” is meant as “do not cross” and used to mark the centerline and to a lesser extent to demarcate the shoulder. Double width lines were used to mark crosswalks with 4-6 feet between the lines. They were also used to mark the stopping point at railroad crossings and street corners. A quick mention of road signs. Information signs were generally white on black or black on white. Here they were black on white for rules of the road (speed limit, right lane only,etc.) and white on black for street and exit signs. Stop signs were generally red but could be yellow. Warning signs such as yield and directional arrows generally yellow. Shapes varied by locale but generally speaking stop signs octagonal, RR crossing were round, yield triangular and everything else rectangular. A good example of roads, at least for California, is in the movie “Mad, Mad, Mad, Mad World”. (First and last half hoursj Hope this helps.. |

Many rural, small towns and subdivision roads didn’t, and still don’t, have any markings at all.

the yellow Posca pens (pigment pens) work very well on black or grey .

Thanks for Your answers, so I will use white lines and my "POSCA" markers ; I must add that I found the attached picture (Detroit, 1965) and the lines seem to be white, the "marks" seemed to be one halfth of a car length, OK for 8 to 10 feet, but the "spaces" seemed to be about 1.5 times this length ; the most interesting is that the traffic lights are already fixed on gallows, and no more at wires ...

Your pictures looks to be Southern California, which may have moved off of wires earlier than other places (because of earthquakes).

And I think Neverland had the best idea, perhaps I will only put the "stop" lines and zebra crossings, and nothing else ... In fact it is really difficult to position exactly the "centerline" on some roads, especially in curves ; I wanted to use masking tape as a ruler, I did so for the white lines at the edges of the roads out of the town. BTW I found the rules for positions of traffic lights, Shapeways has fine lights !

I stand corrected.
