Tahoe Road RAM Road Segment Setup Quick Guide 1 TAHOE ROAD RAM ROAD SEGMENT SETUP QUICK GUIDE The following is an update to the Road RAM User Manual providing helpful hints to establish a road segment This step is performed one time and once established the location and boundary will not change 1 SEGMENT SETUP ONE TIME This step can be initiated in the office using Google Maps or similar and then confirmed in the field 1 1 SELECT 10 000 FT ROAD SEGMENT FOR OBSERVATIONS e Assign each road segment a unique ID e Use a stop sign or crosswalk as one boundary when possible This will provide a safe place to cross street during observations e Never select site on a curve At least 300ft of visibility from oncoming traffic should be available from both directions 1 2 DETERMINE DIMENSIONS OF THE ROAD SEGMENT e Determine road width of all continuous impervious surfaces including sidewalks up to a maximum width of 65 ft If using Google Maps measure in feet If in the field find a safe place to cross the street and count number of paces 1 pace 3 ft Use Table 1 to convert between feet and paces gt Tip Know your personal pace for a 3ft step Practice using measuring tape e Determine road length based on road width to define the consistent 10 000 ft using Table 2 Convert feet to paces using Table 1 e Walk length of the road segment and identify any landmarks to denote boundaries of segment 2NDNATURE LLC ec
