The aim of this study was to provide the client company with a traffic study that would serve as documentation to be attached to the Feasibility Study for the execution of a stretch of service road extension, in order to improve the road safety conditions of this stretch with respect to those that exist in the current situation.
With the approval of the study's management, it was proposed to carry out the study in two different parts, separated in time. The first part was the collection of mobility data in the study environment and the construction of the digital traffic model in a microscopic environment. In a second part, based on the previous base model, the evaluation of accessibility was carried out.
The work carried out for the drafting of this project was as follows:
- Compilation of existing data on traffic demand on the surrounding roads and traffic capacity of the Ministry of Development.
- Installation of 5 artificial vision cameras at the junction in front of the study plot (change of direction junction), the traffic light intersection under the motorway where the exits end and the intersection with the road.
- Video of the route with camera on board the vehicle with georeferencing from the different origins planned at peak times AM and PM, to obtain travel times, delays, average speeds, etc.
Automated counting with artificial vision software from field filming of vehicles on the ground, in order to know the distribution of flows on the surrounding roads.
- Analysis of the Service Level of the surrounding roads following the methodology of the Highway Capacity Manual.
- Study of future traffic allocation based on traffic microsimulation techniques. To this end, a digital model of the environment in which traffic demand is assigned was published.
