SUBJECT: PROPOSED PEDESTRIAN CROSSINGS TO IMPROVE PEDESTRIANSAFETY AT EITHER SIDE OF YEPRENEYE SHOPPING CENTRE

AUTHOR: INFRASTURCTURE MANAGER - STEPHEN BALOBAN

EXECUTIVE SUMMARY

Proposed Pedestrian Crossings at Hartley Street and Bath Street either side of Yeperenye Shopping Centre to improve pedestrian safety

RECOMMENDATIONThat it be a recommendation to Council:

That Council give direction

REPORT

1. BACKGROUND

Council has requested the Technical Service Department to investigate the installation of Pedestrian Crossings at Hartley Street and Bath Street either side of Yeperenye Shopping Centre to improve pedestrian safety.

At the moment pedestrians crossing Hartley Street and Bath Street either side of Yeperenye Shopping Centre use pedestrian refuges in conjunction with road narrowing that is provided by the footpath encroaching into the road which forces the cars to slow down and giving the pedestrians a shorter distance to cross.

2. DISCUSSION

The Technical Service Department have investigated the proposed pedestrian crossings to improve pedestrian safety between Hartley Street and Bath Street either side of Yeperenye Shopping Centre.A pedestrian zebra crossings (Refer attachment A) gives pedestrians right of way to cross the road, there is no waiting time and cars must wait. This enables pedestrians to move comfortably and safely across the road.

The proposed new pedestrian zebra crossings would have to comply with Austroads and the latest Australian Standards; this would include upgrading the street lighting over the crossings

Bath StreetCurrently pedestrians enter exit Yeperenye Shopping Centre directly onto the exiting crossing to the Coles complex. The new pedestrian crossing along Bath Street would be located in the same location as the exiting pedestrian refuge, (Refer to before and after diagrams below)

Report No. 106/16ts Agenda Item No: 9.2Page ..../2

The Technical Service Department has prepared scope and costings for the proposed pedestrian crossing.The new pedestrian crossing would include retaining existing ramps and pedestrian refuge and just painting the zebra crossing on top of exiting and upgrading the street lighting

Hartley StreetCurrently pedestrians enter exit Yeperenye Shopping at either side of the existing fagade along Hartley StreetPedestrians can cross Hartley Street between the Yeperenye Shopping and the Hartley Street Carpark VI two pedestrian refuges

The Technical Service Department propose 3 options for the proposed Hartley Street pedestrian crossing.

Option 1

Remove the two existing pedestrian refuges and open up the exiting facade to the public by removing the glass centre panels and locate the pedestrian zebra crossing central to the Yeperenye shopping centre. Council would have to consult with Yeperenye and seek approval to modify the faced which is located on the Council road reserve

As Council is fully aware no funds have been set aside in the current budget or in the 2016/2017 budget for this project.

Council could possibly look at changing direction on certain existing 2016/17 budgeted works for example, the Footpath program funding, the Tree maintenance program funding, the Tree Planting program funding, the Landfill Rehabilitation program, the Public Toilet Refurbish program etc. and these funds could be steered towards this new project. Please note these are purely suggestions for Council’s consideration.

RE: Hartley Street and Bath Street Zebra Crossing Review, Alice Springs

Dear Stephen,

We refer to your recent request seeking advice regarding the proposal for a pedestrian zebra crossing on either side of the Yeperenye Shopping Centre to improve pedestrian safety across Hartley Street and Bath Street.

As requested, we have undertaken an independent assessment of the subject site, including:

1. A desktop analysis of the subject area and Council’s report to appreciate investigations completed to date.

2. A high level review of pedestrian desire line between attractors and generators.

3. A review against the requirements of introducing of zebra crossing.

REFERENCE DOCUMENTS

The following Austroads Guides and Australia Standards have been referred to in the preparation of this report:

• Austroads Guide to Road Design Part 4 - Intersection and Crossing.• Australian Standards 1742.10 (2009) Part 10: Pedestrian Control and Protection.

TYPES OF CROSSING TREATMENT

The common crossing treatments defined by the Austroads Guide and the Australian Standards applicable to Hartley Street and Bath Street are:

Informal Pedestrian Crossing Facilities:

• Kerb ramp - generally installed at pedestrian desire line of crossing• Median refuge - generally used where pedestrian has difficulty crossing the road in one

stage

• Kerb extension - used to increase sidewalk and provide additional visibility to pedestrian

P \2016\1344\Corres\13603 - Zebra Crossing - Final.docx 1 GREF.NHILI

Formalised Pedestrian Crossing Facilities:

• Zebra crossing - gives priority to pedestrian right of way over road traffic.

• Pedestrian actuated signal - generally used on roads that have relatively high volumes of traffic and pedestrian interaction.

DISCUSSIONS

EXISTING CONDITIONS - HARTLEY STREET

• A two lane two-way road with a 1,2m raised median.• Posted Speed limit 40km/h.

• An estimated average annual daily traffic (AADT) of 6,500 vpd (based on camera systems analytics on the front of Yeperenye Centre at 45 Hartley Street taken in 2013).

• There are 4 median refuges within a 120m of Hartley Street:o One at Gregory Terrace intersection, o Two at the Woolworths entrance, o One at the Post Office.

• Hand rails and pedestrian warning signs are installed.

EXISTING CONDITIONS - BATH STREET

• A two lane two-way road with a wider 1.5m median refuge.• Posted Speed limit 40km/h.

• The median refuge is located in between the Yeperenye Centre entrance and the walkway to the Coles supermarket.

• Hand rails and pedestrian warning signs are installed.

PEDESTRIAN DESIRE LINE

Pedestrian desire line is a key consideration in determining crossing treatment locations. Our

desktop assessment has highlighted desire line between the “pedestrian generator” (the car parking) and "pedestrian attractor” (retail shops and entrances to supermarket). We have summarised this assessment and illustrated in figure below for ease of communication.

PED DESIRE LINE

Figure 1 Pedestrian Desire Line

This analysis indicates that there is a general alignment of pedestrian desire line with the existing pedestrian refuge locations on Hartley Street and Bath Street.

TRAFFIC CONSIDERATION

Traffic implications should also be considered when proposing zebra crossing. As described above, zebra crossing gives priority to pedestrians over street traffic when crossing manoeuvre is being

undertaken. When pedestrian arrival is random and uncontrolled, it can be expected that the driver behaviour will change. It may also introduce congestion and other traffic patterns to develop if planning for its use has not been assessed thoroughly.

REQUIREMENTS FOR ZEBRA CROSSING

The Australian Standard have outlined requirements for which a mid-block zebra crossing can be installed:

• Traffic lane - pedestrian should only negotiate one lane of traffic in each direction.• Adequate sight distance - use of kerb extension to achieve sight distance where kerbside

parking is frequent.

• Speed - 85th percentile road traffic speed shall be 50km/h or lower.• Crossing shall not be used on arterial roads.

Note: the above requirements are not a “Warrant” for zebra crossing.

P:\2016\1344\Corres\13603 - Zebra Crossing - Final docx 3 CRF.ENHILI

Other considerations when assessing a mid-block zebra crossing location includes:

• Lighting

Adequate road lighting shall be installed in accordance with AS1158.4 at road crossing facilitates unless usage is not expected at night time. It is particular important at pedestrian zebra crossing as clear visibility is essential to ensure drivers are able to give way to pedestrian.

• Traffic Signage and Pavement Markings

There must not be any conflicting traffic control devices in the vicinity of the proposed crossing location. The correct signage and pavement markings shall be installed in accordance to AS 1742.10 to formalise the crossing location and also provides advanced warning of the pedestrian facility ahead.

• Other Crossing Points

The effectiveness of a zebra crossing would be affected if there are other crossing points in the immediate vicinity. The New Zealand Government’s Pedestrian Planning and Design guide recommends that zebra crossings should not normally be sited within 100m of any other pedestrian crossing points or signalised pedestrian crossing.

Zebra Crossing Feasibility Evaluation

A high level merit assessment has been undertaken to assess the existing conditions on Harley

Street and Bath Street against the Australian Standards requirements.

Criteria Hartley Street Bath Street

The assessment has identified that Hartley Street pedestrian zebra crossing should not be supported unless the proximity of crossing points are rationalised and there are strategies and infrastructures to funnel pedestrians to the proposed zebra crossing location.

P:\2016\1344\Corres\13603 - Zebra Crossing - Final docx 4 CRF.F.NH III

On the other hand, the Bath Street pedestrian zebra crossing may be feasible subject to further investigations and planning.

CONCLUSION

GREENHILL is supportive to the proposal to improve pedestrian safety within the Alice Springs Town Centre, however, recommends that Council undertakes further investigation to understand the extent of pedestrian safety problems on both streets.

The investigations should include:

1) Analysing the last five-year crash history with a focus on pedestrian related crash.

2) Surveys and pedestrian facility audits to identify:

a. Significant generators and attractors (detail use type) of pedestrian traffic in the AM, PM and late PM peaks Pedestrian trip details since as volume estimates;

b. pedestrian routes; trip origins and destinations; time of day demand; types of pedestrian users; factors that may inhibit walking; and

c. road speed and classification.

3) Pedestrian road safety audit of the existing conditions.4) Traffic querying and intersection capacity analysis.5) Lighting assessment at proposed crossing locations.

Other Safety Improvement Consideration

The Guide to Road Design Part 4 - Intersection and Crossing recommends good practice for the use of pedestrian refuges as outlined below:

• Desirable minimum of at least 2.0m wide refuge to provide adequate separation from traffic flows and particularly where traffic speeds are high.

• A minimum of 1.8m wide refuge to allow for standing of a person wheeling a pram, a person in a wheelchair or walking with a bicycle.

• At least 2.4m wide when considering installing a staggered pedestrian crossing.

All current refuges on Hartley Street and Bath Street do not meet the minimum recommended by the Austroads Guide. Council may consider improve existing refuges to appropriate requirements.

Yours faithfullyfor GREENHILL
