  2. 2. MAKING IT WORK, PLANNING IN A CONNECTED WORLD 10 Transportation Engineering Myths1.  We will never get people out of their cars2.  Americans won’t walk or bike in significant numbers3.  Reshaping city transportation is expensive & takes a long time4.  Fatter lanes are safer lanes5.  A “B” is better than a “D”6.  It’s a zero sum game between peds, traffic and public space7.  Closing or narrowing a congested street leads to gridlock8.  Adding highway capacity is key to reducing congestion9.  Knocking down a highway will cause gridlock10.  “You can’t make an omelette without breaking a few eggs” Brilliant in Design, Clear on Message and Visionary in Expression

  4. 4. 1. WE WILL NEVER GET PEOPLE OUT OF THEIR CARS Trends: Younger people driving less, walking & biking more (active transportation) Source: The Sightline Institute The Future Isn’t What It Used To Be, Victoria Transport Policy Institute•  Portion of 19-yr-olds with a driver’s license fell from 92% in 1977 to 77% in 2008•  Average VMT by drivers aged 16 to 34 dropped by 23% between 2001-2009*•  Bike trips for 16 to 34-year-olds jumped 24% between 2001-2009* *Source: National Household Travel Survey Brilliant in Design, Clear on MessageNew York, NY and Visionary in Expression

  7. 7. 2. AMERICANS WON’T WALK OR BIKE IN SIGNIFICANT NUMBERS ACTIVE TRANSPORTATION Any method of travel that is all or partly human-powered. It refers to transportation that supports walking, stair use, cycling, and transit. It includes long-term land use and transportation planning to encourage alternate (non-motor vehicle) forms of transport. Brilliant in Design, Clear on Message and Visionary in Expression
  8. 8. 2. ENCOURAGING ACTIVE TRANSPORTATION•  Dense cities, mixed land-use generate short trips•  Safe convenient cycling including bike parking•  Connected, direct, and pleasant sidewalks and paths•  Traffic systems and designs with pedestrians and cyclists in mind•  Calm residential neighborhoods•  Walk-to-School programs•  Good transit•  Coordinate transit + cycling + walking•  Laws + enforcement to protect peds + bikes > cars•  Education programs•  Equitable cost of transportation by mode Brilliant in Design, Clear on Message and Visionary in Expression

  26. 26. 4. FATTER LANES ARE SAFER LANES (CONT’D)c)  “Analysis of geometric, traffic volume, and accident data has found… no consistent , statistically significant relationship between lane width and safety for midblock sections of urban and suburban arterials. There is no indication that the use of 3.0- or 3.3m (10-11ft lanes), rather than 3.6m (12ft) lanes for arterial mid segments leads to increases in accident frequency.

  35. 35. 7. CANAL STREET PEDESTRIAN & TRAFFIC SAFETY STUDY “Canal Street may appear to be a busy thoroughfare but it is remarkably inefficient in moving vehicles.” “The vehicles are moving so slowly that, for the most part they are merely providing "seating" on Canal Street and movement is the exception. Clearly, the existing amount of road space is not needed to move so few vehicles.” Brilliant in Design, Clear on MessageNew York, NY and Visionary in Expression
  36. 36. 8. ADDING HIGHWAY CAPACITY IS KEY TO REDUCING CONGESTION “Adding highway lanes to deal with traffic congestion is like loosening your belt to cure obesity.” Lewis Mumford Brilliant in Design, Clear on Message and Visionary in Expression
  37. 37. 8. NYC IS ONLY MAJOR CITY WITHOUT AN INTERSTATE IN CBD Yet cross town speeds in the 1940’s were 6-7 mph about the same as today. 388,000 vehicles entered CBD in 1948, 762,000 enter today.

  38. 38. 8. IF YOU BUILD IT, THEY WILL DRIVE The Fundamental Law Of Road Congestion Evidence From U.S. Cities by Duranton and Turner, 2009•  VMT increases proportionally to roadway lane miles for interstate highways and probably slightly less rapidly for other types of roads•  People drive more when the stock of roads in their city increases•  A new roadway diverts little traffic from other roads.
