• Road Diet approach reduces stormwater runoff and, therefore, water quality improved. Reducing
paving/asphalting reduces also the heat island effect in urban areas. We would love to see in the main
arteries: new drainage and stormwater management provisions, raised bikeways, wider sidewalks,
special route for public transport and traffic calming elements. From year to year we see that stormwater
control is CRUCIAL. Minimize impermeable surfaces where unnecessary. Provide drainage points and
keep then clean from vegetation and leaves. Use " natural drainage " to reintroduce surplus water back
into the soil. Healthy soil and vegetation are the backbone of " natural drainage " systems.
• An excellent tool in decreasing speed and increasing safety (and improving landscaping) is
using Traffic Circles.
• Speed limit enforcement is another successful policy. Declaring of 30 km/h (20 mph )zones reduced
crash rates and increased numbers of cyclists and pedestrians. Other studies have revealed that lower
speeds reduced community severance caused by high-speed roads. Research has shown that there is
more locality interaction and community cohesion when speeds are reduced to 30 kmph
• Dedicated public transport or High-occupancy vehicle (HOV) lanes should be separated from
other traffic at a minimum with solid single or double white stripes. Dedicated public transport/bus
transit lanes require median boarding islands in the roadway at each stop. These stops must be fully
accessible and lead to safe, controlled crosswalks or other crossings. Public transport-only lane may be
applied at curb-sides. Public transport-only lanes require significant enforcement and may be
invaded/trampled by double parked cars and loading vehicles without proper enforcement. Public
transport / HOV lanes should be paired with accessible transit stops in the roadway median where
needed. Red / Yellow colored paint should be applied to emphasize dedicated public transport lanes
and deter drivers from using them. Separation of the dedicated public transport lane with soft barriers
(i.e. rumble strips) and/or hard barriers (concrete curbs) should be considered to reduce encroachment
from moving vehicles. The minimal width of a public transport lane is 3.5-4 metres per direction. Most
cities’ workers who use public bus/HOV/Express lanes say those lanes save them time and influence
their mode choice.
• The more you shift vehicular priority from cars to transit, bicycling and walking – the more you can
spare space for sidewalks, motorized/bicycles parking lots, plazas, bike lanes, and
cafes/bars/restaurants/kiosks. Street furniture, including benches, planters, sculptures, and bicycle
parking, can subtly delineate the motorized ways from the pedestrian-only spaces. Consider
widening sidewalks, especially when they have previously been narrowed in favor of additional travel
lanes.
• Provide appropriate space to allow accesses for walkers, disabled, and bicycle travel and other
wheeled vehicles such as strollers or scooters. Placement of sidewalks on one side or the other of
a road is subject to several considerations like: location of existing adjacent sidewalks; grade and
slope of roadway; avoid sidewalks on the bottom of slope to reduce puddles; location of existing
vegetation and above‐ground utilities that will remain in place. Sidewalk width - 1.2 m (4 feet)
minimum. 1.55 m (5 feet) is preferable. Encourage parking slots or grass plot/planting strip) between
roadway and sidewalk in urban/suburban neighbourhoods. Add more pedestrian amenities in more
dense sidewalk areas such as road crossings, curb‐bulb extensions: benches, lighting, signposts,
trees, trashcans, shelters, water taps, ramps, automated payment machines.
• Ensure pedestrians are not forced into vehicular traffic. Sidewalks have a desired minimum
through zone of 6 feet and an absolute minimum of 5 feet (1.5 m.). Where a sidewalk is directly
adjacent to moving traffic, the desired minimum is 8 feet (2.44 m.), providing a minimum 2-feet (60
cm.) buffer for street furniture and utilities. But, sidewalk design should go beyond the bare minimums
in both width and amenities. Pedestrians and businesses thrive where sidewalks have been
designed at an appropriate scale, with sufficient lighting, shade, and street-level activity. Sidewalks
should be " empty " from gaps or obstacles of construction works. You must consider wheel-chairs
and mothers with baby-carriages. Sidewalks of minimum dimensions directly adjacent to the
traveled way should be avoided. If a sidewalk is directly adjacent to the roadway, 2 feet (0.6 m.)
should be added to the absolute minimum clear path width to ensure that there is sufficient space for
roadside hardware and snow storage. Parking provides a valuable buffer between the pedestrian and
vehicle realm. (Credit, again: NACTO.ORG recommendations).
• Congestions problems: Arguments for enlarging and extending the roads/street infrastructure in
congested, dense-populated neighborhoods – do not hold anymore. Transportation congestion
occurs where/when people travel in limited space during the same period of time. In economic
terms, congestion exists where roads are “underpriced” - motorized demand exceeds road
capacity. Supply-side interventions, like adding road capacity and/or expanding transit services are,
largely, unsuccessful. Travel patterns are adjusting themselves, quickly, to added capacity. The long-
run solution is to attack the demand side. Congestion pricing can effectively manage the demand for
