TSRGD Roadshow 2 00pm graham hanson [compatibility mode]

  1. 1. Workshop Scheme Design for 20 mph scheme Graham Hanson
  2. 2. Reduced time and cost of scheme delivery 20mph zones • Sign illumination can be relaxed throughout a 20mph limit/zone – subject to risk analysis • Remove the requirement for terminal signs to be placed on both sides of the road • Repeater signs can be used as a physical feature • Remove the requirement for a speed roundel to be accompanied by an upright sign • Provided new signs for 20mph part-time limits
  3. 3. Maximum speed limit
  4. 4. Requirements of directions
  5. 5. Traffic management costs • Average speed hump = £2000 • Illuminated traffic sign =£600 • Energy costs and maintenance = £100 pa • Cost to place an unilluminated sign = £200 • Cost to place pair of unilluminated signs (back to back) = £300 • Cost to mark a parking bay = £500
  6. 6. Scheme costs Total cost = £36,200 • 8 x speed hump = £2000 x 8 = £16000 • Illuminated traffic sign = £600 x 16 = £9600 • Energy costs and maintenance = £100 pa = £1600 x 5 = £8000 • 4 back-to-back signs for zone = £4 x £300 = £1200 • 2 x unilluminated parking signs = 2 x £200 = £400 • Mark 2 x parking bay = £500 x 2 = £1000
