The K109 forms part of Gauteng Department of Transport (GDRT) future road network planning aimed to enhance connectivity within the province and to other provinces. The K109 in its entirety is planned to run in a north-south direction commencing from R101 (Old Pretoria Main Road) in Halfway House and terminating at M39 in Brakfontein. Figures 1and 2 shows the extent of K109 between Halfway House and Olifantsfontein and Figure 3 shows the K109 in the context of the future road network planning. The purpose of this study is to inform the detailed design of the route with regards to design standards that are applicable in terms of lane requirements, pavement design and access management. 2 Scope of Study It is important to note that the study is not intended to deal with any proposed township applications or to provide an opinion on any application that has been submitted. The scope of the study entails the following: To determine the expected heavy vehicles along the corridor for the estimation of E80 axial loading to be used in the pavement design Estimate expected future traffic volumes over 20 year design period to establish typical design requirements for the road as a single or dual carriageway; Conduct capacity analysis to determine concept designs of the proposed intersection as well as the required intersection control; Review the proposed access/intersection positions against the Road Classification and Access Management (RCAM) requirements and recommend changes if necessary; and Assessment non-motorised transport (NMT) and public transport requirements along the proposed corridor. 3 Background to K109 The K109 forms part of GDRT future road network planning aimed to enhance connectivity within the province and to other provinces. The K109 is planned to run in a south-north direction commencing from R101 (Old Pretoria Main Road) in Halfway House and terminating at M39 in Brakfontein. This route will provide an alternative to the congested M1 and Old Pretoria Road (R101) as well as Allan Road in connecting Midrand and Centurion. This study, however, only addresses the portion of K109 between Halfway House and R562 (K27) in Olifantsfontein. The route alignment is planned off bituminous Dale Road through undeveloped land, round the Glen Austin nature reserve, to join the alignment of TRAFFIC IMPACT ASSESSMENT| FINAL| JULY Page 1 K109 TRAFFIC IMPACT STUDY APHA NE CONSULTING GAUTENG DEPARTMENT OF ROADS AND TRANSPORT Van Rebeeck Road and thereafter stretches over undeveloped land until its intersection with R562 (K27). Van Rebeeck Road intersects with George road and Olifantsfontein Road (D795) along its length. 4 Surrounding Road Network Allan Road Allan Road/ Modderfontein Road runs in a north- south direction starting from Dale Road and intersecting with Douglas Road, George road and Olifantsfontein Road and terminating at its intersection with R562 (K27). Allan Road/ Modderfontein Road functions as a class 3 road, a minor arterial. It is a single carriageway with one lane in each direction. Dale Road Dale Road functions as a connector road road running in an east –west direction. Dale road starts from Old Pretoria Road (R101), intersects with Allan Road/ Modderfontein Road (M38) and several local access roads to the surrounding residential areas along its length and ends as a cul de sac in Kaalfontein. Dale Road is a single carriageway road with one lane in each direction. Van Reibeeck Road Van Rebeeck Road is a gravel Road which functions as an access road on the western boundary of Glen Austin AH residential area. TRAFFIC IMPACT ASSESSMENT| FINAL| JULY Page 2 K109 TRAFFIC IMPACT STUDY APHA NE CONSULTING GAUTENG DEPARTMENT OF ROADS AND TRANSPORT Douglas Road Douglas Road functions as a local access road within the Glen Austin AH residential area. It runs in an east-west direction has one lane in each direction throughout its length. Douglas Road is 5m wide and has traffic calming in the form of speed bumps. George Road Similar to Douglas Road, George Road functions as a local access road within the Glen Austin AH residential area. It also runs in an east-west direction starting from Van Rebeeck Road, intersecting with Allan Road/ Modderfontein Road and Old Pretoria R oad ending as a cul de suc just before the N1. George Road has one lane in each direction throughout its length. It is 5m wide and has traffic calming in the form of speed bumps Olifantsfontein Road Olifantsfontein Road also runs in running in an east-west direction. It connects Olifantsfontein to the north-western suburbs of Johannesburg. Olifantsfontein starts as a class 3 road at its intersection with R562 (K27) until its intersection with the Old Pretoria Road. Thereafter, it proceeds as a class 2 road to Plantation Road in Midrand. TRAFFIC IMPACT ASSESSMENT| FINAL| JULY Page 3 K109 TRAFFIC IMPACT STUDY APHA NE CONSULTING GAUTENG DEPARTMENT OF ROADS AND TRANSPORT R562 (K27) R562 (K27) is a provincial road running in an east-west direction that extends between R101 and R21 in Tembisa. Olifantsfontein is a dual carriageway road with two lanes in each direction. 5 Existing Traffic Volumes Detailed traffic counts were undertaken on Thursday, 19 June 2014 as part of the K109 corridor study at the following intersections: Allan Road/Dale Road; Dale Road/Archefish Drive; Dale Road / Licensing offices Access; Douglas Road/ Van Riebeeck Road; George Road/ Van Riebeeck Road; Olifantsforntein Road / Van Riebeeck Road; and Olifantsfontein Road / R562 (K27) These traffic counts are summarised in Figures 4 and 5 for the AM and PM peak hours respectively. The following observations can be made: Allan Road: The AM two-way traffic flow between Dale Road and Douglas Road is 937veh/hr. There is approximately a 70:30 split in north: south traffic flow. During the PM this section of the road experiences similar traffic volumes (914veh/hr.) as the AM peak hour with an approximate balanced split in north: south flow; Dale Road: The section of Dale Road between Allan Road /Modderfontein Road and Archerfish Drive has two-way traffic flow of 1075veh/hr
