37.4.2. Pedestrian crossings

Pedestrian crossings are provided at places where the conflict between vehicular and pedestrian traffic is severe. The site should be selected that there is less inconvenience to the pedestrians and also the vehicles are not interrupted too much.

Pedestrian crossings are strategically placed areas on roadways designed to facilitate safe passage for people crossing the street. They are usually implemented in locations where high volumes of cars and pedestrians interact, which can lead to safety issues. The selection of these sites is crucial; they should ideally balance the need for safe pedestrian access with minimal disruption to vehicle flow. This ensures that pedestrians can cross safely while not causing excessive delays to drivers.

Think of a busy intersection near a school. A pedestrian crossing here allows children and parents to cross the street safely after school. If the crossing was placed directly in front of the school, it might create confusion for drivers and lead to traffic delays. Instead, placing it a bit further down the street means students can still cross safely while keeping the traffic flowing smoothly.

At intersections, the pedestrian crossings should be preceded by a stop line at a distance of 2 to 3m for unsignalized intersections and at a distance of 1m for signalised intersections.

Stop lines are markings on the road that indicate where vehicles must stop when they encounter a red traffic signal or a stop sign. The distances mentioned—2 to 3 meters for unsignalized intersections and 1 meter for signalized intersections—ensure that vehicles do not block the pedestrian crossing zone, allowing for safe passage. By having these specific distances, it also helps in minimizing conflicts between pedestrians and vehicles, contributing to overall road safety.

Imagine you are approaching a stop light at an intersection. The stop line is your cue to halt, ensuring you don’t roll into the pedestrian crossing. This ensures that people waiting to cross the road can do so without dodging traffic, much like how a football player waits behind a line of scrimmage until the play begins.

Most commonly used pattern for pedestrian crossing is Zebra crossing consisting of equally spaced white stripes of 500 mm wide.

Zebra crossings are identified by alternating white and black strips across the road, designed to alert drivers to the presence of pedestrians. The stripes are 500 mm wide and are spaced evenly, making them visually distinct. This pattern not only signifies a pedestrian right of way but also encourages drivers to slow down as they approach. The design is intended to increase visibility and awareness of pedestrians needing to cross the road, emphasizing safety.

Think of the Zebra crossing like a crosswalk where pedestrians get a special 'pass' to walk. Just as a zebra has black and white stripes, the crossing has these bright markings that call attention to drivers, making it easier to spot pedestrians wanting to cross, much like how a highlighted book passage helps you remember key information.

A typical example of an intersection illustrating pedestrian crossings is shown in Figure 37:11.

Figures accompanying guidelines, such as Figure 37:11, are critical in visually demonstrating how pedestrian crossings are designed and positioned within an intersection context. These illustrations can help convey the practical application of the principles discussed, showing the spacing of stop lines and pedestrian crossings in relation to vehicular lanes. This visual representation aids in understanding the dynamics of pedestrian movement and traffic flow.

Visual aids in instructions are like road maps for travelers; they provide a clear picture of where to go. For instance, when you're planning a road trip, a map shows the routes, just as figure visuals illustrate where pedestrian crossings and stop lines fit into real-life roads, helping to ensure everyone can navigate safely.
