INTRODUCTION 1.1 Background Following completion of the Dowse to Petone upgrade of State Highway 2, Hutt City Council (HCC) has been concerned to ensure there is adequate provision for cyclists accessing southwest Petone or travelling through the area. This study has been commissioned to investigate suitable strategies for managing cycle traffic, whether within the highway corridor, on parallel routes such as Hutt Road, or on new routes yet to be formed. Location of the study area is shown in Figure 1 below. MELLING DOWSE DRIVE PETONE RAMPS FIGURE 1: Location of study area Page 1 Page 2 Provision for cyclists in southwest Petone The investigation has been carried out by Barclay Traffic Planning with assistance from Boulter Consulting. 1.2 Scope Objectives of the study include maximising safety for cyclists and promoting the use of cycles through improved facilities. The investigation is intended as a scoping study, with possible measures considered at a concept level only. It is intended that costings and feasibility considerations will be researched as part of more detailed investigations at a future date. Barclay Traffic Planning 30 March 2012 Page 3 2. DESCRIPTION OF ROAD NETWORK 2.1 Hierarchy Traffic management by both New Zealand Transport Agency (NZTA) and HCC is based on a well-structured roading hierarchy which as far as possible separates the functions of through and access traffic movement. At the top of the hierarchy and part of the strategic national network is State Highway 2. This is identified in the Hutt City District Plan [1] as a Primary Distributor Road, the highest possible classification, for which the predominant function is to be through movement. Next highest are Major District Distributor Roads, also intended primarily for through movement. Within the study area this classification is represented by The Esplanade, which provides for through movement within Hutt City. These roads are complemented by Minor District Distributors, including Hutt Road, Railway Avenue, Parliament Street, Bridge Street, Pharazyn Street and Block Road. Typically, these have a mixed function, with both through and access movement. The final level in the Distributor road network is Local Distributor, providing access to local areas. These include Udy Street, Dowse Drive, Normandale Road, Bridge Street and London Road. All non-distributor roads in the study area are classified as Access Roads, for which access functions predominates over through movement. Cycling is a flexible, low-impact transport mode, and cycle routes do not need to be strictly consistent with the roading hierarchy. High status roads however do tend to have direct and continuous routes with a minimum of frontage activity, making them attractive for cyclists, especially those travelling longer distances. 2.2 Road characteristics Physical characteristics of each road are generally in line with its hierarchy status. State Highway 2 between Melling and the Petone ramps is now close to motorway standard, with grade separated intersections and almost no direct property access. In addition it has four lanes with central median barrier, an alignment suitable for speeds of 80 to 100 km/h, and generous shoulders. The main parallel route is formed by Block Road, Pharazyn Street, Bridge Street, Parliament Street and Hutt Road. These have two-lane carriageways, generally with parking on both sides. Carriageway width varies between 10.0 and 15.7 metres. A typical view of Hutt Road is shown in Figure 2. Page 4 Provision for cyclists in southwest Petone FIGURE 2: Typical view of Hutt Road Traffic volumes along the two routes are shown in Table 1. North of Petone, State Highway 2 has a flow of more than 35,000 veh/day, and south of Petone the flow is close to the maximum capacity of a four-lane road. On the Pharazyn-Hutt route, flows are more moderate but still substantial for a two-lane road. In general flows are around 10,000 veh/day but there is a sharp increase in the section between Dowse Drive and Railway Avenue.

(Note: at the time of writing a complete record for the 2011 year was not available.) It should be noted that the Dowse Interchange was completed during the sample period, and the record will only partly reflect the benefit of safety improvements, especially those in the highway corridor. It will be seen that for the State Highway 2 route a total of 265 crashes were recorded, of which 54 resulted in injury. This compares with a total of 177 for the Hutt Road alternative, including 39 injury accidents. Fatal Serious Minor Non- injury injury injury State Highway 2: Melling intersection 1 8 45 211 to Petone Ramps Route: Block Rd, Pharazyn St, 1 6 32 138 Bridge St, Parliament St, Hutt Rd TABLE 2: Crash record Although State Highway 2 has a higher crash frequency than the Hutt Road route, it has a lower crash rate because of its higher flow, that is 17 reported injury accidents per 100 million vehicle-kilometres, compared with 36. Crash rate is a measure of personal risk and enables the safety performance of roads with different flow rates to be compared. The rates of 17 and 36 are well within expected norms for the respective road types. These comparisons are reflected in the crash record for cycles, shown in Table 3. Cycle injury crashes State Highway 2: Melling intersection to Petone Ramps 3 Route: Block Rd, Pharazyn St, Bridge St, Parliament St, Hutt Rd 6 TABLE 3: Injury crashes involving cyclists For the highway, crashes included one on the Petone on-ramp, one near Cornish Street and one near the former Korokoro Road intersection. On the Page 6 Provision for cyclists in southwest Petone Hutt route, five of the six crashes occurred at intersections. Apart from the on- ramp collision, which can be said to be characteristic of bicycles, crash patterns for both routes appear to be similar to those of motor vehicles. In the absence of cycle flow data it is not possible to quantify relative crash rates for cycles on the two routes. It must also be recognised that in absolute terms the figures in Table 3 are small and the comparison will be affected by random variation. The figures do however
