Find ud af om polyline går gennem polygon

Jeg har nogle polylines (en række koordinater, der repræsenterer en rute)

Jeg har også en polygon (et rektangel lavet ud fra 4 koordinater)

De stammer fra et Google Map (API v3).

Jeg har så brug for at vide om nogen af mine polylines krydser eller overlapper polygonen, og i så fald hvilke(n) der overlapper/krydser.

Polygon koordinater (eksempel):

55.409900930568234, 10.37313580127784
55.409900930568234, 10.366806598722178
55.40630766943176, 10.366806598722178
55.40630766943176, 10.37313580127784

Polygonen genereres fx ud fra følgende kode:

    //lav en cirkel og gem bounds fra den
    var cb = new google.maps.Circle({
        center: new google.maps.LatLng(55.4081043, 10.3699712),
        radius: 200
    }).getBounds();

    //lav liste over koordinater der repræsenterer bounds på cirklen:
    var polyCoords = [
        new google.maps.LatLng(cb.getNorthEast().d, cb.getNorthEast().e),
        new google.maps.LatLng(cb.getNorthEast().d, cb.getSouthWest().e),
        new google.maps.LatLng(cb.getSouthWest().d, cb.getSouthWest().e),
        new google.maps.LatLng(cb.getSouthWest().d, cb.getNorthEast().e)
    ];

    //lav en polygon der viser bounds for cirklen:
    var radiusPoly = new google.maps.Polygon({
        paths: polyCoords,
        strokeColor: '#FF0000',
        strokeOpacity: 0.8,
        strokeWeight: 2,
        fillColor: '#FF0000',
        fillOpacity: 0.35,
        map: map
    });

Jeg håber på en funktion der tager imod polygonen og polyline-array'et, og returnerer en liste over hvilke polylines der rammer polygonen.
Altså noget der kaldes i stil med:

var result = checkForIntersects(radiusPoly, polylines);

Resultatet kunne så fx være "0,1" hvis de første to rammer, eller bare "" hvis ingen rammer.

Her er nogle eksempel polylines (ruter).
Mindst én af disse rammer polygonen, men det skal selvfølgelig også virke hvis ingen rammer den.

var polylines = [];
var path = [

Jeg kan godt se at det er svært, nu skal vi jo til at lave svær matematik, jeg ved heller ikke hvordan man gør, men vi kan prøve at samarbejde herinde, så kan vi moske finde en løsning.

Vi finder først ud af hvordan vi regner det ud, og så kommer jeg med scriptet.

Jeg fandt noget der skulle kunne klare beregningerne, men jeg fik en del JS fejl da jeg forsøgte.

Det kan selvfølgelig ske at jeg leverede data i et forkert format måske?

Jeg kan ikke huske den præcise fejl, og jeg kommer ikke hjem til min pc med projektet før mandag aften :-(

Men jeg kan prøve at lave en JSfiddle så i kan se det selv :-)
- når jeg kommer hjem altså :-)

Fandt aldrig en løsning, og projektet blev siden droppet :-(
