Traffic Survey

Traffic surveys consist of various types of data collection techniques done by surveying various aspects of traffic flow. These include the following services: pedestrian counts, turning movement counts, bicycle counts, turning movement counts, link flow traffic counts, rail and bus punctuality surveys, travel time surveys, roundabout counts, parking survey methodology, queue length surveys, number plate recognition, illegal movement surveys and traffic saturation flows.

Turning movement counts :
Turning movement count is a traffic count survey method that enables assessing the movement of vehicles, traffic flow and delay characteristics in greater than three arms. The data collected from a turning movement count survey is used to develop improvement plans for critical intersections in the short term.

Link flow traffic counts :
Link flow traffic counts are easily obtainable by individual vehicle types. We use link count tools to accurately collect data that will let us predict traffic flow precisely. Link counts are effective in providing street-level traffic data.

Bicycle counts :
This is a method of traffic flow analysis based on non-motorised traffic including bicycle traffic and pedestrian traffic. The number of bicycle counts however, is limited over space and thus is not dependent on the type of road user.

Pedestrian counts :
Pedestrian count surveys collect useful data related to pedestrian traffic behaviour. They enable the identification of traffic volume, the time taken to cross the road, any obstructions, and the usage frequency of crossing infrastructure. The level or frequency of conflict between cyclists or pedestrians can also be determined through pedestrian counts.

Queue Length Surveys :
Typically this involves queue management techniques by recording the number of vehicles in a queue before the traffic signal turns green for one or all legs on an intersection. It also involves the recording of the volume of each lane queue depending on the length of the queue, and by taking into account the number of lanes that exist.

Journey Time Surveys :
Journey time or travel time surveys are done using portable GPS units installed in survey vehicles. Data collection is possible through travel time surveys at pre-determined locations. It depends largely on the number of moving vehicles and can also relay information relating to queue times at each feature, such as signalled junctions. The GPS data is downloaded when the precise OSGR location of the back of the queue (determined via a significant reduction in speed) and the time of passing the agreed timings point are shown.

Roundabout Counts :
Roundabout Count Report is a method of traffic data collection which helps in determining the capacity and performance efficiency of roundabout approaches. It sums up the turning movement volume (TMV) of a roundabout. It also clearly details the entry, traffic circulation and exit flow rate for each roundabout leg, from origin to destination.

Rail & Bus Punctuality Surveys :
Commuter services like the railways define punctuality as arrival within 3 minutes of the stipulated time. Punctuality surveys enable passengers to rate the commute or journey on the basis of various parameters. These include the time taken waiting for the bus or train, their satisfaction with the overall journey and their view of whether they received value for money.

Journey Time Surveys :
Journey time or travel time surveys are done using portable GPS units installed in survey vehicles. Data collection is possible through travel time surveys at pre-determined locations. It depends largely on the number of moving vehicles and can also relay information relating to queue times at each feature, such as signalled junctions. The GPS data is downloaded when the precise OSGR location of the back of the queue (determined via a significant reduction in speed) and the time of passing the agreed timings point are shown.

Parking Survey Methodology :
The main objective of the parking survey methodology is to assess usage levels for on and off-street parking. This type of survey also enables the identification of key issues and constraints in parking demand and supply characteristics.

Number Plate Recognition :
Number plate recognition or the ANPR system is a mass surveillance method involving the capture of images to enable the manual reading of vehicle registration plates manually. The images collected through number plate recognition involve large volumes of data which we arrange, sort and analyse to translate them into meaningful data points for your business.

Illegal Movement Survey :
Tracking illegal movements on the road such as traffic violations, parking in a no-parking zone, and unloading goods in a non-loading zone and so on is enabled through illegal movement surveys. These surveys are extremely helpful in traffic management and collating data on traffic offenders.

Traffic Saturation Flows & Degree of saturations (DoS) :
The traffic saturation flow rate at signalized intersection can be measured to determine the capacity of the current roadways and intersections in handling traffic volumes. It is defined as the number of vehicles per hour that could cross the line if the signal remained green all of the time. It enables urban infrastructure planning in terms of whether new roads, flyovers and intersections need to be built with respect to the traffic flows on existing intersections. It also helps in setting times for traffic signals to change in order to handle traffic. The data is calculated on the assumption that there is a continuous queue of vehicles with minimal headways. It is also based on evaluating the maximum number of vehicles that would pass through the intersection if the lane was in continuous green signal for that hour.

Some of the other specialized services we provide include on & off street parking surveys, queue Length Surveys and classified turning counts.
