Equipment
We have recently acquired a vehicle and several instruments from Race Technology Ltd, such as the DL1 MK3 DataLogger with a GPS antena, the VIDEO4 with 4 HD cameras and audio input, the SpeedBox featuring very accurate accelerometers and GPS antenna, a LIDAR rangefinder, and wheel and pedal sensors.
Case studies
Roundabout's capacity, safety and emissions in Coimbra, Portugal
This research was focused on using appropriate modeling methodologies to understand the effects of turbo-roundabouts on capacity, safety and emissions, in comparison with conventional single-lane and double-lane roundabouts.
We have worked on site using an equipped vehicle, video cameras, pneumatic tube detectors and viacounts to measure speed and count vehicles.

Car following in Coimbra, Portugal
We have proposed a low-cost procedure to calibrate the Gipps car-following model. The trajectory data was collected with a car equipped with a datalogger and a LIDAR rangefinder. The datalogger combines GPS and accelerometers data to provide accurate speed and acceleration measurements. The LIDAR measures the distances to the leading or following vehicle.

Turbo-roundabouts in Grado, Spain
The goal was to characterize the environmental impacts of turbo-roundabouts depending on traffic and the likelihood of occurrence of different speed profiles. Furthermore, we were aiming to determine the gap acceptance at the entry of a turbo-roundabout.
For this we have used the equipped vehicle with a DL1 MK3 connected with a VIDEO4 and a set of video cameras on site.
