Intersections <br />Design C~uidel fines <br />1) Intersection design should consider the trade- <br />offs between increasing vehicle capacity, transit <br />needs, and improving pedestrian and bicycle <br />mobility and safety in situations where conflicts <br />are evident. <br />2) Multi-modal intersection design should <br />consider and accommodate appropriate level of <br />service, design speed, and types of traffic. <br />3) All modes of travel should be accommodated <br />in multi-modal intersections. Intersection widen- <br />ing for additional turn lanes to relieve conges- <br />tion should provide for and encourage transit <br />movements, as well as safe pedestrian and <br />bicycle movements. <br />4) The preferred location for pedestrian crossings <br />is at intersections. However, mid-block pedes- <br />trian crossings can be installed if warrants are <br />met. (See Mid-Block Crossing Standards). <br />5) Wide streets can present an impediment to <br />pedestrian crossings. Pedestrian refuge medians <br />and/or landscaped medians with pedestrian <br />refuges should be designed into arterial and <br />collector street intersections with more than three <br />lanes, whenever possible, to reduce crossing <br />distances and improve safety and comfort for <br />pedestrians. <br />6) Generally, provide striped crosswalks at stop <br />controlled intersections when the minimum hourly <br />pedestrian crossing volume (for peak four hours) <br />exceeds 25 on streets with average daily traffic <br />(ADT) At locations where a significant number of <br />pedestrians are children, elderly, or disabled, <br />minimum crossing thresholds are 10 pedestrians per <br />hour on streets with average daily traffic (ADT) <br />identified in the above cited references. Use this <br />guideline as long as the basic criteria governing <br />sight distance speeds, etc. are met. For details <br />regarding this guideline, see references cited in the <br />Mid-Block Crossing section. <br />7) Median signal heads and pushbuttons should <br />be considered for placement on unusually wide <br />intersections. <br />8) Provide right lanes at intersections for buses to <br />use for "queue jump" operations. The lane may <br />be exclusive to transit or could include other <br />vehicles sharing the. right turn <br />lane. Additional widening on <br />the far side of the intersection <br />should be considered for far- <br />side bus stops and bus merge <br />areas. <br />9) Avoid intersection designs <br />with dual right-turn lanes, <br />particularly with .one of the <br />lanes being a shared through- <br />right turn lane. <br />68 <br />Areas with multiple curb cuts increase accident potential <br />and reduce the efficiency of the street <br />
