Qatar Survey Analysts and Traffic Consultants, together with Surtech International Limited Qatar, are separate companies that form part of an existing multi national Urban Planning and Development Consortium whose experience range some forty years within the Residential, Commercial and Industrial sectors of Subdivisions, Roads and Infrastructure Developments.
Qatar is the most exciting region in the Middle East for future planned and calculated sustainable Development. The road and traffic components for the future of Qatar play a significant and major contribution to the overall success of a workable and achievable Infrastructure system, and the accurate survey and definition of existing conditions allow the instigation of successful designs.
Our specialist teams of traffic and surveying consultants are fully conversant with the requirements and detail required for effective traffic forecasting, urban design and land development. QSA and Surtech International use the most up to date equipment, software and video monitoring available.
Our staff are fully conversant with Occupational Health and Safety regulations, quality control systems, site survey and preparation methods, plan preparation, inspections and monitoring.
Qatar Survey Analysts and Surtech International provide the following services :
- Automatic Traffic Counts
- Manual Classified Counts
- Turning Movement Counts
- Pedestrian Volume Counts
- Topographical / Laser Scanning Surveys
- Ground Penetration Surveys
- Engineering / Construction Surveys
- Control, Detail and Levelling Surveys
Automatic Traffic Counts
ATCs are mechanical surveys undertaken by the placement of counting tubes across relevant roadway carriageways for a period of one week (seven days). The ATCs record traffic volume on an hourly basis for the entire week providing 15 and 60 minute summaries as required. ATCs also provide data for vehicle volumes, classification and speeds. Commonly utilised traffic survey information derived from ATCs which can be used in the design process for intersections and road networks is the average annual daily traffic (AADT), the 85th percentile speed and heavy vehicle percentages.
Turning Movement Counts
TMCs are manually undertaken classified counts that include the number of passenger vehicles, trucks and buses for each movement, primarily taken at intersections. In addition, pedestrian and bicycle movements across all intersection or route approaches/carriageways shall be included. The TMCs shall consist of 3 separate counting periods of three hours each (totalling 9 hours) These counts shall be scheduled to capture morning, noon and afternoon/evening peak periods and will be based on the results of the ATCs previously presented.
Manual Classified Counts (Manual and/or Video)
MCCs are similar to TMCs however they are conducted over a continuous 16 hour period recording the traffic volume and classification for a particular roadway on a 15 and 60 minute interval basis. Similar to TMCs, MCCs will be scheduled to capture the peak operational periods of the subject roadway which will be based on the results of the ATCs
Manual Count Types
Turning Movement Counts – counts at an intersection recording the required through and turning movements of vehicles on each leg of the intersection.
Mid Block Volume Counts – volume counts by direction. Sometimes used to check automatic tube count data.
Origin Destination Surveys – usually done be recording number plate of vehicle at a number of stations to monitor trip routes. Can be done manually or with Automatic Number Plate recognition software.
Travel Time Surveys – Three methods of survey are used by QSA
- 2 person crew driving route using stopwatch or similar to record times between various timing points along the route.
- Using GPS logger to record route and times of vehicles.
- Recording number plates at various stations along a route and matching plates recorded to gain regularity of times matched.
Pedestrian Movement Counts
Counts of pedestrian movements that can be done in association with a turning movement count or separately.
Parking surveys are usually done in 30 minute or one hour cycles over the given survey period, but can be any nominated time cycle.
Duration of stay Parking Counts
The usual method is to record and number the available spaces within the survey area and then record the number plate of the vehicle in each space on each cycle
Alternative method is to record the number plate, entry and exit times of vehicles at car park entry points. Plates are then matched and duration of stay is calculated.
Occupancy Parking Counts
These are basic parking counts where an inventory of available spaces and restrictions are recorded and the counts of the number
Special Purpose Surveys
Various other surveys can be conducted including driver behaviour observations, and other surveys such as recording the number of passengers in vehicles.
Topographic / Laser Scanning Surveys
Topographic Surveys are carried using conventional total stations, kinematic GPS data acquisition, and the facilitating of photogrammetric mapping from 3DLS land and airborne laser scanning to enable the generation of detail and contour plans used for design purposes in the Urban Planning, Road and Drainage design phases of Road, Subdivision and Engineering and Infrastructure works. The data will show all existing structures, services, landscapes and facilities. The data will also enable accurate calculation of volumes and digital terrain modelling.
Ground Penetration Surveys
Underground services detection surveys are used to detect underground utilities that may not be on record, using ground penetration radar and cable avoidance tool. This can also avoid the need for digging trial test pits.
Engineering / Construction Surveys
Surtech International carry out all forms of Engineering and construction surveys including infrastructure facilities, roads, railways, overland conveyors, process plants, overhead transmission lines, oil and gas pipelines, route location surveys, earthworks, quantity computations, setting out of roads, drainage and buildings, works as executed and any other associated survey component.
Control, Detail and Level Surveys
Based on the Qatar National Grid and Qatar National Height Datum, accurate surveys are carried out using existing CGIS control stations to co ordinate vertical and horizontal control for use in the determination of cadastral boundaries, detail topographical surveys, road alignments and general accurate ground locations. The data can be converted to plan and electronic format and can be used for all GIS related surveys and data collection.
