The need for study implementation responded to the following issues:
- The determination of the required technical parameters for further modernisation of road (additional capacity, widening of cross section or adding new traffic lines);
- Providing the Level of Service study, thus the need for implementation of additional lanes for achieving the desired Level of Service;
- Determining noise levels and other environmental parameters;
- Defining an essential input of financial and economic data for multi criteria analysis.
Crucial element of the Project was development of network model that represented, within different scenarios, the existing road network and the new road network as a result of proposed interventions.
Traffic Study also included Traffic Survey for defining directional journeys between Avila – Maqueda and inside the study area. In total Traffic Survey took place on 13 survey locations along the road. The exploitation of the survey helped in identifying a origin – destination matrix of long trips, i.e. traffic that currently passed through the corridor. Subsequently developed the origin – destination matrices are used for the model calibration and projection. The final stage of Project required: model calibration of the current situation, successive analysis of proposed alternatives for different time horizons by conducting an iterative process for obtaining balances networking functions.
Eptisa carried out the following activities:
- Delineation and zoning corridor and the study area in order to identify points of potentially origin and destination flows;
- Analysis of the current situation of traffic;
- Development of a simulation model of transport networks using CUBE software, world wide recognized software for transport planning from CITILABS company;
- Development of a growth model for calculating future mobility based on observed user behavior, historical mobility within the corridor and demographic projections;
- Calculation and determination of Levels of Service following the methodology and software associated with the Highway Capacity Manual, Transport Research Board; and
- Proposing adequate improvement alternatives.
