Intersections Design Guidelines 1) Intersection design should consider the trade- offs between increasing vehicle capacity, transit needs, and improving pedestrian and bicycle mobility and safety in situations where conflicts are evident. 2) Multi-modal intersection design should consider and accommodate appropriate level of service, design speed, and types of traffic. 3) All modes of travel should be accommodated in multi-modal intersections. Intersection widen- ing for additional turn lanes to relieve conges- tion should provide for and encourage transit movements, as well as safe pedestrian and bicycle movements. . 4) The preferred location for pedestrian crossings is at intersections. However, mid-block pedes- trian crossings can be installed if warrants are met. (See Mid-Block Crossing Standards). 5) Wide streets can present an impediment to pedestrian crossings. Pedestrian refuge medians and/or landscaped medians with pedestrian refuges should be designed into arterial and collector street intersections with more than three lanes, whenever possible, to reduce crossing distances and improve safety and comfort for pedestrians. 6) Generally, provide striped crosswalks at stop controlled intersections when the minimum hourly pedestrian crossing volume (for peak four hours) exceeds 25 on streets with average daily traffic (ADT) At locations where a significant number of pedestrians are children, elderly, or disabled, minimum crossing thresholds are 10 pedestrians per hour on streets with average daily traffic (ADT) identified in the above cited references. Use this guideline as long as the basic criteria governing sight distance speeds, etc. are met. For details regarding this guideline, see references cited in the Mid-Block Crossing section. 7) Median signal heads and pushbuttons should be considered for placement on unusually wide intersections. 8) Provide right lanes at intersections for buses to use for "queue jump" operations. The lane may be exclusive to transit or could include other vehicles sharing the right turn lane. Additional widening on the far side of the intersection should be considered for far- side bus stops and bus merge areas. Areas with multiple curb cuts Increase accident potential and reduce the efficiency of the street 26 9) Avoid intersection designs with dual right-turn lanes, particu larly with one of the lanes being a shared through- right turn lane.
