i m looking for urban design traffic engineering ideas to fix a conflictive intersection area in baltimore md specifically where russell st meets hamburg st right where a highway off ramp feeds into the surface street context traffic comes off the ramp and the road transitions from 2 lanes down to 1 lane shortly after there s a median in this area that s asymmetrical on one side it includes a bike lane plus a separate service road running alongside it on the other side of the road the median is simpler more standard this asymmetry combined with the lane drop right after the ramp creates merging conflicts and confusing traffic flow for drivers coming off the ramp goal i want to redesign this so that the service road is preserved it needs to stay functional the median on the messy side is reconfigured to mirror the cleaner median design on the other side of the road traffic flow off the ramp is smoother and less conflictive reducing weaving confusion or unsafe merges caused by the lane drop and median layout i ve attached an image where i sketched the current road layout ramp lanes median bike lane service road to show what i mean what i d like from you please generate multiple design iterations options for reconfiguring this median and lane transition considering traffic calming and merge safety at the lane drop keeping the bike lane protected functional keeping the service road intact and accessible sightlines and driver predictability coming off the ramp any relevant best practices from nacto aashto or similar urban street design guidelines for ramp terminals and asymmetrical medians for each iteration briefly explain the tradeoffs cost complexity space needed impact on bike ped safety impact on vehicle flow
