How much safer are livable streets? • Per vehicle mile traveled: • 40% fewer midblock crashes than roadway averages. • 67% fewer roadside crashes than roadway averages. § Examined lengths of arterials in 3 small metro regions: § Substantial design variation: § Pedestrian-oriented “livable” streetscape @CompleteStreets in downtown core. Implementing Context § Conventional suburban. Sensitive Design § Suburban/rural transition. Source: Eric Dumbaugh, Texas A&M

Crossing Toolkit 3: Warrants From MUTCD: • They (traffic signals) are used to interrupt heavy traffic at intervals to permit other traffic, vehicular or pedestrian, to cross. Pedestrian Warrant • The Pedestrian Volume signal warrant is intended for application where the traffic volume on a major street is so heavy that pedestrians experience excessive delay in crossing the major street. • The criterion for the pedestrian volume crossing the major street may be reduced as much as 50 percent if the 15th-percentile crossing speed of pedestrians is less than 3.5 feet per second. • School Warrant and Progression Warrant Pedestrian Hybrid Beacon • A pedestrian hybrid beacon may be considered for installation to facilitate pedestrian crossings at a location that does not meet traffic signal warrants . 86 @CompleteStreets Implementing Context Sensitive Design

“Metro areas that invested heavily in road capacity expansion fared no better in easing congestion than metro areas that did not. Trends in congestion show that areas that exhibited greater growth in lane capacity spent roughly $22 billion more on road construction than those that didn’t, yet ended up with slightly higher congestion costs per person, wasted fuel, and travel delay.” –Surface Transportation Policy Project 91 @CompleteStreets Implementing Context Sensitive Design
