SERVICES - INDUCTIVE LOOP INSTALLATION

All our works are carried out by fully trained to Industry Standard Operatives. Every site is installed to current MCH1540 specification. Only the highest quality, and to full specification materials are used on each installation; oxidized bitumen, epoxy resin, inductive loop cable to the TR2029 specification, ducting, chambers. Every site installed on completion will be fully tested for inductance and continuity and working fully to specification. A fully comprehensive test sheet will be completed and signed by our senior unit operative and a copy forwarded to the client.

 

Motorway Midas Loop - motorway traffic and signal data obtained from MIDAS (Motorway Incident Detection and Automatic Signaling) loops. MIDAS detector loops are placed in every lane of a motorway spaced ideally every 500m. The loop data are assembled into files which records count, speed, traffic density and vehicle length, averaged for each minute of the day. Electronic Counters then takes this data, including signal settings and motorway geometry, processes the information in a specified form and produces detailed graphical outputs of the behavior of traffic or operational performance of the controlled motorway systems.
 
Traffic Counting Systems - One of the cornerstones of Automatic Counting System success is the ability to automate all counting irrespective of distance, location and environment. The remote electronic counting system records automatically without human intervention, monitoring 24 hours a day, 7 days a week and 365 days a year. Data is processed in real-time and a report [daily or weekly] is sent to the customer automatically. In an event an alarm has occurred (due to insufficient/excessive count), our system will automatically notify the customer for immediate actions to be taken.
 
Traffic Signal Loop - There is something exotic about the traffic lights that "know" you are there -- the instant you pull up, they change! How do they detect your presence? Some lights do not have any sort of detectors. For example, in a large city, the traffic lights may simply operate on timers -- no matter what time of day it is, there is going to be a lot of traffic. In the suburbs and on country roads, however, detectors are common. They may detect when a car arrives at a junction, when too many cars are stacked up at a junction (to control the length of the light), or when cars have entered a turn lane (in order to activate the arrow light). There are all sorts of technologies for detecting cars - everything from lasers to rubber hoses filled with air! By far the most common technique is the inductive loop. An inductive loop is simply a coil of wire embedded in the road's surface. To install the loop, they lay the asphalt and then come back and cut a groove in the asphalt carriageway with a diamond saw. The wire is placed in the groove, sealed with epoxy resin, and topped up with oxidized bitumen.
 
Speed Detection,– Another major advance in technology is Speed Detection loops used for the ‘Speed Camera’ (much to the abhorrence of drivers) – these operate very similar to the Midas loop in that the loops are spaced for measurement. The system operates by the vehicle traveling over the loops, which calculates an average speed by reading number plates a set distance apart and measuring the time taken. As a vehicle drives past the first camera/loop, the infrared sensors either side of the camera take a reading of the number plate. Now the vehicle drives past the second camera/loop and the information is stored again. From the information received, it can calculate exactly how long it has taken that vehicle to travel from point A to B. By calculating distance traveled over time taken it can work out your average speed within the zone. The information can then be relayed by transmitting to a central office via telephone /modem links or recorded on discs stored in cabinets at the roadside. So if vehicle speed is in excess of the limit, this is recorded within the camera, the information is translated very quickly in order for the Camera to operate and by ‘flashing’ to take a picture of the license plate. We all know what happens after that……..
 
Weight Detection – Weigh in Motion Sensors (as opposed to cable) are placed in the carriageway for Weight Detection. These are most commonly used for Department of Transport regulations with regards to vehicle loaded weight.
 
Ice Detection – Temperature sensors place in the carriageway and are connected to a weather station. The information can then be accessed via remote dialup connection. Detection and warning of adverse weather enables reactive maintenance, whereas prediction enables proactive anti-icing operations in advance of the onset of forecast weather.
 
Bridge Tolling – Loops installed at bridge tolls used for control of barriers – something which we envisage will become more and more in forthcoming years. The loop detects the vehicle and connects to the barrier therefore operating the barrier arm.
 
Car Park Loops – Loops installed at car parks are used for control of barriers – And the actual control of available car parking spaces. The loops actually count the amount of vehicles going in and going out of the car park thus ensuring that you there is no blockage within the car park.
 
Bicycle Loops – Loops are installed on the carriageway for our eco-friendly bicycle lanes – These specialised loops work under the same principle as per the Traffic Signal Loop, only detecting bicycles.
 
Traffic Management Services – All areas of traffic management are available from localized coning to full Motorway Chapter 8. Road space bookings and drawings are another service we offer in our turn key packages.
We manage the complete traffic management solution - from liaison with the Client to the Highway Authorities through to the on-site delivery. This includes site survey; traffic management schematic drawings; liaison with Local Authorities, Route Managers and Police; application and receipt of all roadspace bookings, temporary traffic regulation orders and necessary road closure permits; method statements & risk assessments.
   
Maintenance and Repairs – All of Lochwynd inductive loop operatives are fully trained in the fault finding and testing of existing inductive loop arrays. And a fully detailed site report will be supplied specifying the maintence works required. We will then carryout out all maintance and repairs as required, including all jointing requirements. Fully completed test sheets are provided to the client for each maintence fault.
   
Roadside Furniture – Lochwynd has a range of on site cabinets to suit all needs of various manufactures counting equipment we can supply and install specific cabinets suitable of accepting mains with and internal distribution board. These cabinets are manuf actured on behalf of Lochwynd are also suitable for installing eco friendly solar panels where mains are not a viable option.
