7. Traffic Calming Measures

Traffic Calming Measures

Introduction

By now you should be independent with your moving off/stopping, clutch control, gear changes including P.O.M, and be able to move off from the side of the road. Also you should be getting better at reading the road in front, beside and even behind your vehicle while you are driving so it’s time to develop your skill with static hazards like chicanes, speed bumps and passing places  (awareness and planning).

Teaching Strategy
On this lesson your instructor will reduce their instruction as appropriate on any previous topics covered and give you as much support on the M.S.P.S.G.L/ L.A.D.A routines. These routines will be used when meeting traffic calming measures in addition to improving the skills learnt last lesson i.e. adequate clearance when passing stationary vehicles and meeting traffic.

The hazard and L.A.D.A routine during this lesson will be will be given by your instructor to a level to suit you… full talk through then reducing to either prompt or independent.

Lesson aims

The aim of today’s lesson is to learn how incorporate the hazard and L.A.D.A routine into negotiating chicanes, speed bumps and passing places and know how to hold back safely and what speed to negotiate them. During this lesson you will be assessed on your general drive but your instructor will be giving you as much support as you need. 

Objectives

Your objective will to be as independent as possible on your general drive, you will be given as much help on the new topic brief as required and by the end of your lesson be able to negotiate chicanes, speed bumps and passing places, whilst also improving your road position and use of your mirrors with little or no help from your instructor.

Lesson brief

Traffic calming measures were designed to improve safety for motorists, pedestrians and cyclists in the 1930s. The aims were to encourage safer, more responsible driving and potentially reduce traffic flow. Urban planners and traffic engineers have many strategies for traffic calming, including narrowed roads and speed bumps. This will reduce deaths but has the capacity to increase rear end shunts.
Chicanes
Single lane chicanes require one direction of traffic to give way to oncoming vehicles. The chicane normally consists of a raised curb and bollard in one half of the road, with a sign to explain the vehicle traffic priority. For the lane without traffic priority, they are to give way. 
Groups of chicanes are normally placed with alternating priority down a road, so that each direction of vehicle traffic may have to stop and give priority in equal amounts. 

Effectiveness:-

● Chicanes reduce accidents by around 29%.
● Reduced vehicle speeds increases safety on the road.
● Breaking distance is reduced, so the vehicle can stop more quickly before a hazard.
● A slower moving vehicle will exert less energy on occupants as the vehicle rapidly changes speed on impact (crashes). ● A slower moving vehicle will transfer less energy to a pedestrian in the event of a collision.
Chicanes format is exactly the same as Meeting traffic

When you approach the chicane plan ahead and react accordingly, give way appropriately with the signs.
Mirrors-Signal-Manoeuvre and L.A.D.A routine a minimum of 3 times. 

Once before you move out.
Once before you overtake the stationary vehicle.
Then again before you move back to your normal road position. 
Speed Bumps
Speed bumps, or speed breakers, are the common name for a family of traffic calming devices that use vertical deflections to slow vehicle traffic in order to improve safety conditions. 
 
There are different designs of bumps… speed hump, speed cushion, and sleeping policemen.
The use of vertical deflection devices has been widespread around the world from 1906, they are most commonly found to enforce a low speed limit, under 15mph or lower. Unfortunately they can increase traffic noise and may damage vehicles if traversed at a too quickly. They also slow down emergency vehicles. 
Poorly-designed speed bumps that stand too tall or with too-sharp an angle (often found in private car parks) can be disruptive for drivers and may be difficult to navigate for vehicles with low ground clearance even at very low speeds. Many sports cars have this problem with such speed bumps. Speed bumps can also pose serious hazards to motorcyclists and cyclists if they are not clearly visible, though in some cases a small cut across the bump allows those vehicles to traverse without impediment.

Going over a speed bump
So all you will need to do is check your –
  • Mirrors (All)
  • Position (central to the bump)
  • Speed (reduced to a walking pace 10/12mph)
  • Gears down (probably 2nd gear) 
Once you are over the bump check your
  • Mirrors (All)
  • Position move to your normal road
  • Speed (increase) 
  • Gears to making progress.
So as you can see, the hazard routine doesn’t need to use in full but needs to be done in order.
Passing places

A single track road or one lane road is a road that permits two-way travel but is not wide enough in most places to allow vehicles to pass one another (although sometimes two compact cars can pass). This kind of road is common in rural areas across the United Kingdom. To accommodate two-way traffic, many single track roads especially those officially designated as such are provided with passing places. The distance between passing places varies considerably depending on the terrain and the volume of traffic on the road.
Reflect & Review

So remember your instructor is there to HELP you, so on your driving lesson if you have any uncertainties or need anything rewording or recapping to make things any clearer, just ask.

Your training vehicle is fitted with dual controls and if necessary will be used during your lesson. These are there for your safety so we can step in to keep you safe.

So don’t worry if the issues arise. We will aid and guide you VERBALLY or PHYSICALLY.

Risk management
Physical control of your vehicle 

The aim is for you, the student, to have full control of this lesson as with previous lessons, and have full talk through on the new topic with your instructor reducing the support throughout.

Your instructor’s job is to analyse any faults that may occur in this lesson and put them right, also to talk about any issues on the driving lesson and put issues right.

● Fault identification.
● Fault analysis.
● Remedial action.

Level of instruction on your lesson.

● Full talk through.
● Prompt.
● Independent.

End of lesson.

● Feed back at the end of your lesson.
● Student’s responsibility during lesson and improvements.
● Plan for the next lesson.
