Traffic Concerns

 

The government is planning a 12.7 minute delay for northbound PM peak traffic on Concord Road to get through a single set of lights. Compare this for whole journey times for Eastern Suburbs residents to the centre of the CBD:

Moore Park in 7.8 mins
Paddington in 8.3 mins
North Sydney in 11.4 mins
Rosebery in 11.6 mins
Edgecliff in 8.6 mins

(source Cross City Tunnel EIS table 7.14)

 

Either the revised Transport Management Plan or the draft plan exhibited or both must contain gross errors, which I believe calls into question the competence of the planners or the assumptions they were obliged to make as a result of their instructions from their client. 

The projected average delay in 2016 after the Rhodes Redevelopment is complete are now:

From   To Average Delay Minutes 
Concord Rd PM HBD 13 
Alfred St PM HBD 5
Mary St PM HBD 15
Llewellyn St AM HBD 3
Averill St PM HBD 1

Compare this for whole journey times for Eastern Suburbs residents to the centre of the CBD:

Moore Park in 7.8 mins
Paddington in 8.3 mins
North Sydney in 11.4 mins
Rosebery in 11.6 mins
Edgecliff in 8.6 mins

See the Table of Differences and they didn't even use 2000 figures as the base!!!

Why? Maybe because the delays in Concord Road at Homebush Bay drive are way higher in 2000 than they were in 1998!

The flow in the latest plan is 32% greater without any development than the original draft plan with the development!

As a result of input from Paul Hanly, the Community Representative appointed by the Council of the City of Canada Bay, at a meeting of the DCP (Development Control Plan) Steering Committee, consultation with Rhodes Peninsula Group representatives regarding the draft Transport Management Plan took place with DUAP (Dept of Urban Affairs and Planning) and their consultants and RTA (Roads and Traffic Authority). As a result of this a revised TMP was prepared.

Rhodes Peninsula Group (thanks to Alan Jeffery) has reviewed the revised plan. Some of his comments sent to DUAP by RPG as a result of this review are:

"We are very interested in how the delays have been dramatically reduced in TMP/2. Some of the more perplexing are:

· The delay experienced by the existing (1998) PM traffic travelling northward along Concord Rd toward the Homebush Bay intersection is reduced by 80% from 477 secs to 95 secs. The only reason given for this appears to be the conversion of the southbound Homebush Bay Drive bus lane to an additional general traffic lane. Is this correct? In addition, despite a 40% increase in the 2016 all-up AM flow at this same location the delay drops from 521 secs to 244 secs.
· Similarly, at this same location in the PM, the 2016+Australand+Development Scates flow is over 62% higher than the TMP/1 2016+Development flow, yet the delay goes from 1484 secs (24.7 mins) to 763 secs (12.7 mins).
· At this same location, the AM Scates base case 1998 (existing) average delay is given as 45 secs (reduced from 121 secs in TMP/1). On 14/6/01 a totally random check around 8:40am showed a delay of around 13 minutes (780 secs) with freely moving traffic in Homebush Bay Drive. Less than a week earlier a Rhodes resident reported taking 25 minutes to get through this intersection to Rhodes. Although this represents only two random checks it does place serious doubt over the credibility of the Scates model. However, this matter can be easily resolved by providing the RPG with the data from the monitoring carried out to calibrate the base case Scates model. The calculation of the average delay using these data will need to be based on a statistically sound sample size and distribution. We look forward to viewing these data.
· The AM 2016 all-up Scates flows through the Alfred St intersection increase by around 12% and yet the delay in Concord Rd falls by almost 90% from 49 secs to 6 secs. There does not appear to be any additional works planned for this intersection which could cause this.

We again express our concern that, presumably in order to promote the viability of this development, proven ridiculously low background growths and vehicle transport modal splits have been adopted. In reality, this area is certain to become a major bottleneck especially given the degree of future proposed development in the surrounding area. The impact of these developments continues to be ignored in these plans. Accordingly, we ask the following questions:
· what financial contributions are being asked of the developers of the Rhodes Peninsula and Australand sites toward the regional road network, not purely those works associated with access to the sites?
· what discussions have been held with Australand to ensure that an easement is provided on their site to permit the construction of a cloverleaf which will doubtlessly be required at the intersection of Homebush Bay Drive and Concord Rd?"
