A suggestion for an alternative zone polygon for Histon Rd, which would capture the Busway B buses as well as the Citi 8:

"zone.id":          "histon_road_2_in",
"zone.center":{"lat":52.22435180109905,"lng":0.11204455161282567},
"zone.zoom":15,
"zone.path":[{"lat":52.23292109111349,"lng":0.1101562764663413},
    {"lat":52.232158859330546,"lng":0.1135895040054038},
    {"lat":52.21520239018069,"lng":0.11208746695706395},
    {"lat":52.21462391579756,"lng":0.10998461508938817}],
"zone.finish_index":2,

"zone.id":          "histon_road_2_out",
"zone.center":{"lat":52.22435180109905,"lng":0.11204455161282567},
"zone.zoom":15,
"zone.path":[{"lat":52.21520239018069,"lng":0.11208746695706395},
    {"lat":52.21462391579756,"lng":0.10998461508938817},
    {"lat":52.23292109111349,"lng":0.1101562764663413},
    {"lat":52.232158859330546,"lng":0.1135895040054038}],
"zone.finish_index":2,

Thanks for the suggetsion (and the one for Milton Rd). We'll keep it in mind when we are next working on this part of the system.

I'd need to go through the process of rendering the new zone on a map and comparing it to the previous one - the essential question is whether this zone alters the transit time for the existing buses or not, i.e. have the start/finish lines moved? My suspicion in any case is these are most likely to be NEW zones in addition to the existing zones rather than replacements. But if anyone already has the comparison then let us know and save us that work.

There is another outstanding issue that the 'Backs' zones are redundant, as they're not drawn to correctly trap the 'U' bus that goes through those zones (i.e. the 'U' bus steps out of the side of the zones before reaching the finish lines and so never flags a zone transit)

This would be a new zone as the start line is to the south of King's Hedges Rd. Similarly for the Milton Rd polygon: the finish line is before the Elizabeth Way-Highworth Ave roundabout.
