Instead, the persons interviewed indicated that certain crossing treatments could be more effective than others in certain street environments with particular ranges of traffic characteristics. For example, several cities use crossing treatments with steady or flashing red signal displays on highvolume, high-speed roadways to achieve better motorist yielding in this high-risk street environment.

For example, Redmond recently adopted an approach that includes pedestrian volumes that are 80 percent of the values included in the MUTCD. Other cities incorporate reduction factors for different street environments or different pedestrian populations (e.g., school children, elderly pedestrians, and those with physical disabilities)

Transit Agency Involvement with Pedestrian Crossings and Traffic Signals Transit agencies are active in providing safe crossings. Following is a summary of transit agency involvement: • The level of coordination varies between transit staff and city engineers.

When determining the amount of traffic control to be used at a pedestrian crossing location, many factors should be considered.Those that affect the perception of pedestrians most are • Traffic volume, • Turning traffic, • Presence of pedestrians with handicaps, • Traffic speed, and • The availability of an alternate crossing. This study revealed that, as the control at a pedestrian crossing increases through the addition of signs, flashing lights, and/or signals, the pedestrians' perception of safety also increases.

Many engineers expressed difficulty in using the pedestrian traffic signal warrant to address pedestrian crossing problems. Some engineers had developed a modified pedestrian signal warrant process that was less restrictive than the MUTCD warrant.
