Safety <br />The safety review includes evaluating the crash records for the crossing <br />location. Pedestrian crashes may necessitate a more in-depth look at the <br />issues and concerns at a crossing location. <br />Rear -end crashes at a location may indicate that motorists are stopping <br />for pedestrians, but they may also indicate that there is inadequate stop- <br />ping sight distance. Other types of crashes should be reviewed to deter- <br />mine if the conflicts are impacting the crossing safety and if they indicate <br />other intersection concerns. <br />Stopping Sight stance <br />Every pedestrian crossing location should have adequate stopping sight <br />distance (SSD). If adequate SSD cannot be provided at a potential cross- <br />ing location, the location may not be suitable for a pedestrian crossing. <br />Adequate SSD ensures that most motorists under normal conditions will <br />be able to stop for a pedestrian that has entered the roadway. <br />If adequate SSD is not provided, consider pedestrian barriers and pedes- <br />trian routing to alternate crossing locations. <br />C Level of e vice Analysis <br />To determine the level of service (LOS) of the current <br />crossing condition, follow the procedure outlined in the <br />2010 Highway Capacity Manual. The methodology follows a six -step <br />program, as shown below. <br />Step 1: Identify Two -Stage Crossings <br />gag. <br />1110' <br />Step 2: Determine Critical Headway <br />Step 3: Estimate Probability of a Delayed Crossing <br />Step 4: Calculate Average Delay to Wait forAdequate Gap <br />Step 5: Estimate Delay Reduction due to Yielding Vehicles <br />Step 6: Calculate Average Pedestrian Delay and Determine LOS <br />14 <br />
