South Dublin County Council Newlands Cross Grade Separation Traffic Modelling: Working Paper No. 1 A review of the DTO, SDCC and Dublin City traffic databases was carried out to minimise the amount of additional traffic survey work required. This resulted in a significant reduction in the number of new traffic counts required for the study to only 11 of the above sites. All additional traffic counts were classified into ‘HGV’s’ and ‘Cars and LGVs’. Journey time surveys along a number of key competing routes were also undertaken. These were used for calibration and validation purposes. 2.1.5 Calibration and Validation The DTO strategic model was initially calibrated to 2002 conditions and therefore recalibration of the local model to 2005 traffic conditions was required. Cordon counts were used to calibrate the model provided by DTO to ensure it reflected the 2005 AM peak operation on the network. Link flow validation was carried out along two screenlines. The first screenline runs from north to south of the proposed network immediately to the west of the M50 and comprises 8 sites. The second screenline runs immediately to the south of the N7 and comprises 4 sites. Check of turning movements at key junctions against current count data was also carried out. Journey time validation was carried out for the routes mentioned above to ensure robust calibration and validation of the model. Validation of queues, delays and turning movements at the Newlands Cross junction was undertaken to ensure correct modelling of existing AM peak operation of the junction in SATURN. 2.1.6 Construction of Opening and Future Year Models Network and Multimodal Adjustments A number of road network upgrades (M50 Upgrade , Dublin ORR) and PT improvements (Metro, Demand Management) will be operational by 2009 and 2024. The following road network improvements were included in the future scenarios: • Phases 1 2 and 3 of the Dublin Outer Ring Road; • M50 upgrade, N4 to N7 only (PPP Improvement assumed as not operational for this scenario); The additional SATURN coding associated to the proposed network upgrades was carried out by the DTO and provided to Arup Consulting Engineers. Future Year Matrix Construction Multimodal assessment of planned Network upgrades and PTI improvements was carried out by the DTO. This ensures that traffic growth factors for each of the traffic matrix zones take into account planned PT improvements and network upgrades. Arup also obtained 2009 and 2024 cordoned matrices from the DTO’s strategic SATURN model to ensure consistency between the Newlands Cross SATURN local model and the DTO’s strategic model for each of the future year scenarios. Review of Future Year Demographics A review of future year demographics was carried out for twelve zones in proximity to Newlands Cross as a further check to ensure that realistic future year matrices have been produced.
