CityEngine: creating multiple medians

BrendanHarmon

Hi, I would like some advice on creating multiple medians. I'm working with the Redlands Redevelopment 2014 street_construction rule. I'd like to be able to create extra medians between the bike lanes and the street lanes for example.  Any advice on how to go about it?

Changes to street_construction.cga

attr Median_Right = false attr Median_Left = fase medianWidthAdjusted = case oneWayStreet: 0 else : Median_width medianWidthAdjustedRight = medianWidthAdjusted(0) medianWidthAdjustedLeft = medianWidthAdjusted(2) medianWidthAdjusted(dir) = case (dir == 0 && Median_Right) || (dir == 2 && Median_Left) : Median_width  else : 0 availableForLanesRound1 = streetWidth - parkingLaneWidth(0) - parkingLaneWidth(2) - bikeLaneWidth(0) - bikeLaneWidth(2) - medianWidthAdjusted(0) - medianWidthAdjusted(2) StreetsidesStep3 -->   case Protected_Bike_Lanes:   split(v,unitSpace,0) {   bikeLaneWidthRight : BikeLane(0) |   parkingLaneWidthRight : Parking(0) |   medianWidthAdjusted : Median(0)   laneCountRight * laneWidthAdjusted : Lanes(0) |   laneCountLeft * laneWidthAdjusted : Lanes(2) |   medianWidthAdjusted : Median(2)   parkingLaneWidthLeft : Parking(2) |   bikeLaneWidthLeft : BikeLane(2) }   else:   split(v,unitSpace,0) {   parkingLaneWidthRight : Parking(0) |   bikeLaneWidthRight : BikeLane(0) |   medianWidthAdjusted : Median(0)   laneCountRight * laneWidthAdjusted : Lanes(0) |   laneCountLeft * laneWidthAdjusted : Lanes(2) |   medianWidthAdjusted : Median(2)   bikeLaneWidthLeft : BikeLane(2) |   parkingLaneWidthLeft : Parking(2) }

You are in the right part of the code. The rule "StreetsidesStep3" has two cases. One where the bike lane is protected by the parking, and the other where bike lanes swap with parking. In both cases, the whole road is being split into right and left lanes, parking, median, and bike lanes. The parameters (0) and (2) tell which side of the street you are on. So you could add more cases here, or just rearrange these cases. In any case, that rule is the place to do it. Does this make sense? If not, I can elaborate.
