Explore the IRC Code: 9-1972 for traffic census on non-urban roads. A detailed guide on conducting accurate traffic surveys for better road planning.

‍

Cyclists sharing the carriageway with motor vehicles and other road traffic can create hazards for themselves and others, particularly when cycle traffic is heavy. To enhance safety and ensure the smooth flow of traffic, it is essential to segregate cyclists from other road users. The Indian Roads Congress (IRC) has established guidelines for the design and layout of cycle tracks to promote safer cycling environments.

‍

‍

Scope

‍

These recommendations apply to cycle tracks constructed alongside roads or independently of them, ensuring that cyclists have dedicated spaces for safe travel.

‍

Definition

‍

A cycle track is defined as a pathway or part of a roadway specifically designed and constructed for the use of pedal bicycles, where a right-of-way exists.

‍

Justification for the Provision of Cycle Tracks and Their Capacity

‍

Justification

‍

Separate cycle tracks are warranted when peak hour cycle traffic reaches 400 or more on routes with 100 to 200 motor vehicles per hour. If motor vehicle traffic exceeds 200 per hour, separate cycle tracks may be justified even with only 100 cyclists per hour.

‍

Capacity

‍

The capacity of cycle tracks can be categorized as follows:

‍

• One-way traffic:some text
  • Two lanes: 2,000 to 5,000 cycles per day
  • Three lanes: Over 5,000 cycles per day
  • Four lanes: Over 5,000 cycles per day
• Two-way traffic:some text
  • Two lanes: 500 to 2,000 cycles per day
  • Three lanes: 2,000 to 5,000 cycles per day

‍

Types of Cycle Tracks

‍

Cycle tracks are classified into two main groups:

‍

1. Cycle tracks parallel to or along a main carriageway:some text
   • Adjoining cycle tracks: These are at the same level as the carriageway.
   • Raised cycle tracks: These are adjacent to the carriageway but elevated.
   • Free cycle tracks: These are separated from the carriageway by a verge and can be at the same or different level.
2. Independent cycle tracks: These are constructed away from any carriageway.

‍

Note: A free one-way cycle track on each side of the carriageway is preferred, and adjoining cycle tracks should be avoided whenever possible.

‍

Design Specifications

‍

Horizontal Curves

‍

Cycle tracks should ideally have horizontal curves with a minimum radius of 10 meters (33 ft). For tracks with gradients steeper than 1 in 40, the minimum radius should be 15 meters (50 ft). Independent cycle tracks should have the largest possible radii.

‍

Vertical Curves

‍

Vertical curves at changes in grade should have a minimum radius of 200 meters (656 ft) for summit curves and 100 meters (328 ft) for valley curves.

‍

Sight Distances

‍

Cyclists should have a clear view of at least 25 meters (82 ft). For cycle tracks with gradients of 1 in 40 or steeper, a clear view of at least 60 meters (197 ft) is recommended.

‍

Lane Width

‍

The handlebar width of a cycle ranges from 45 to 50 centimeters (1 ft 6 in to 1 ft 9 in). Considering the need for maneuverability, a total width of 1 meter (3 ft 3 in) is required for the movement of one cycle.

‍

Width of Pavement

‍

The minimum width for a cycle track should be at least 2 meters (6 ft 6 in) for two lanes. If overtaking is necessary, the width should be increased to 3 meters (9.8 ft). Each additional lane should be 1 meter (3 ft 3 in) wide.

‍

Clearance

‍

• Vertical Clearance: A minimum headroom of 2.25 meters (7.38 ft) should be provided.
• Horizontal Clearance: At underpasses, a side clearance of 25 centimeters should be allowed on each side, making the minimum width for a two

‍

Conclusion

‍

The design and layout of cycle tracks are crucial for promoting safe and efficient cycling, particularly in urban environments where traffic congestion is prevalent. By adhering to the guidelines set forth by the Indian Roads Congress, planners and engineers can create dedicated spaces that not only enhance the safety of cyclists but also improve the overall flow of road traffic.

‍

Implementing well-designed cycle tracks—whether adjacent to roadways or independent—ensures that cyclists can navigate their routes with confidence, free from the hazards posed by motor vehicles. The recommendations regarding gradients, sight distances, lane widths, and clearances are essential for accommodating the diverse needs of cyclists while maintaining accessibility and usability.

‍

Ultimately, investing in the infrastructure for cycling not only encourages more people to choose this sustainable mode of transport but also contributes to healthier communities and reduced environmental impact. By prioritizing the safety and comfort of cyclists, we can foster a culture of cycling that benefits everyone on the road.
