TRAFFIC & TRANSPORTATION SURVEYS
Classified Traffic Volume Count Survey
2. O&D SURVEY
.Origin - Destination Survey
3. AXLE LOAD SURVEY
Traffic volume count surveys will be conducted at mid block / screen line survey locations for 16/24 hours for 3/7 Days. The data has to be analysed to estimate intensity of traffic, hourly variation, composition, and peak hour characteristics. The survey locations and formats will be finalized with clients as per Project Requirement.
We have Latest Traffic Count Solutions are :-
ATCC (Automatic Traffic Counting & Classification) with Pneumatic Tube Counts.
ATCC (Automatic Traffic Counting & Classification) with Videographic Counts Using Image processing system .
Videography Based Automatic Counting with Using High Definition Cameras with superior Video Quality.
Manual Vehicle Counts at site.
Origin - Destination survey identifies the travel pattern of vehicles along a road network. This survey spots where most vehicles originate in a network and finish their journey and it also shows how often they take this path. We use advanced technologies including ANPR, Bluetooth and expert manual methods. This can also be done using Roadside Interviews depending upon the location and feasibility. OD surveys of people can also be collected manually by interviewing them.
The only effective way to compare the damaging effect of traffic on given roads is to measure the complete spectrum of axle loads and calculate the appropriate equivalence factors. Axle loads and gross vehicle weights can be measured by static or dynamic methods. In a static method, vehicles are stopped to measure their axle loads; the Transport Research Laboratory (TRL) portable weighbridge and the wheel weighing pad are often used for this purpose.
Turning Movement Traffic count
Turning movement will be conducted at Junctions / roundabout continuously for 16/24 hrs. The data has to be analysed to estimate intensity of traffic, hourly variation, composition, Turning moment and peak hour characteristics. The survey locations and formats will be finalised with clients.
Our experienced team can count any junction layout that varies from a basic T-Junction to a complex multiple camera roundabout or Big Gyratory with any number of vehicle Classification. We are specialized in 100% Lane-by-LaneVehicle tracking on Large roundabouts.
PAVEMENT INVESTIGATION SURVEYS
Subgrade soil & Pavement material
Sampling & testing.
Falling Weight Deflectometer Teting
Road construction project requires the site investigation to be carried out to understand the soil profile. For road construction works, the properties of soil at subgrade level are required.The common soil test for road construction includes classification of soil, particle size distribution, moisture content determination, specific gravity, liquid limit and plastic limit tests. Moisture content, particle size and specific gravity tests on soils are used for the calculation of soil properties such as degree of saturation.
An FWD is used as a testing device for measuring the physical properties of pavement. This is a nondestructive and non-intrusive process, and is generally preferred over other destructive testing, because tests are not only faster but also do not entail removal of pavement material (Belt et al., 2006). The relevant ASTM standard (ASTM D4694, 2006b) states that the vehicle should be brought to a stop with the loading plate positioned over the desired test location. The FWD process applies dynamic loads to a pavement surface, simulating the magnitude and duration of a single heavy moving wheel load. The peak deflections at each measured location are recorded in micrometers
1.ROAD PAVEMENT ROUGHNESS
The International Roughness Index (IRI) is used by highway professionals throughout the world as a standard to quantify road surface roughness. A continuous profile along the road is measured and analyzed to summarize qualities of pavement surface deviations that impact vehicle suspension movement.
