  2. Slip lane - Wikipedia

    en.wikipedia.org/wiki/Slip_lane

    Normally, pedestrian signals in the UK operate on a full pedestrian stage in which all traffic is held at red, and all pedestrian crossings are given a green signal. With a slip lane, pedestrians can cross to the triangular island during the vehicle red phase and cross the road while the traffic from their approach has a green light. [5]

  3. Geometric design of roads - Wikipedia

    en.wikipedia.org/wiki/Geometric_design_of_roads

    Circular curves are defined by radius (tightness) and deflection angle (extent). The design of a horizontal curve entails the determination of a minimum radius (based on speed limit), curve length, and objects obstructing the view of the driver. [4] Using AASHTO standards, an engineer works to design a road that is safe and comfortable.

  4. Complete streets - Wikipedia

    en.wikipedia.org/wiki/Complete_streets

    New road distribution in Davis, California. Now pedestrians and cyclists have better safety conditions. Now pedestrians and cyclists have better safety conditions. The specific design elements of Complete Streets vary, based on context and project goals, but they may include:

  5. Pedestrian safety through vehicle design - Wikipedia

    en.wikipedia.org/wiki/Pedestrian_safety_through...

    One of a series of safety research vehicles produced by British Leyland in the 1970s including a pedestrian-friendly bonnet. In May 2013, the World Health Organization (WHO) reported that more than 270,000 pedestrians lose their lives on the world’s roads each year, accounting for 22% of the total 1.24 million road traffic deaths.

  6. Traffic calming - Wikipedia

    en.wikipedia.org/wiki/Traffic_calming

    Traffic engineers refer to three "E's" when discussing traffic calming: engineering, (community) education, and (police) enforcement.Because neighborhood traffic management studies have shown that residents often contribute to the perceived speeding problem within their neighborhoods, instructions on traffic calming (for example in Hass-Klau et al., 1992 [4]) stress that the most effective ...

  7. Protected intersection - Wikipedia

    en.wikipedia.org/wiki/Protected_intersection

    The design makes a turn on red possible for cyclists. In many cases, the cyclist who is separated from motor traffic can turn right without even needing to come to a complete stop. [20] This protected intersection design features a number of common elements that optimise safety: A corner refuge island with a reduced turning radius

  8. Permeability (spatial and transport planning) - Wikipedia

    en.wikipedia.org/wiki/Permeability_(spatial_and...

    A recent comparison of seven neighbourhood layouts found a 43 and 32 percent increase in walking with respect to a conventional suburban and the traditional grid in a Fused Grid layout, which has greater permeability for pedestrians than for cars due to its inclusion of pedestrian-only paths (filtering). It also showed a 7 to 10 percent range ...

  9. Highway engineering - Wikipedia

    en.wikipedia.org/wiki/Highway_engineering

    Highway engineering (also known as roadway engineering and street engineering) is a professional engineering discipline branching from the civil engineering subdiscipline of transportation engineering that involves the planning, design, construction, operation, and maintenance of roads, highways, streets, bridges, and tunnels to ensure safe and effective transportation of people and goods.
