Keeping Christchurch Moving: Post EQ Traffic Management

Transcription

1 Keeping Christchurch Moving: Post EQ Traffic Management Michael Blyleven Transport Planning Manager NZTA Paul Burden Road Corridor Operations Manager CCC October 2011

2 Christchurch Earthquake Half Christchurch s roads suffered some damage More than 50,000 road surface defects recorded More liquefaction esp. near rivers Roads closed - became carparks

3 Post EQ immediate response CCC signals team re-establish power/communications Working together CCC/NZTA/consultants/contractors to review road network defects to review network performance to identify traffic relief initiatives to identify re-location of businesses Strategic Routes Team formed

4 Strategic Routes Team Paul Burden (CCC), Road Corridor Operations Manager Michael Blyleven (NZTA), Transport Planning Manager and UDS Transport Group Ryan Cooney (NZTA), Transport and traffic engineer Steffan Thomas (CCC), Traffic Operations Team Leader Robyn Gardener (CCC), Transport safety team leader Lawrie Timpson (CCC), SCIRT Traffic Management coordinator Sean Lewis (CCC), Traffic Signals Team Leader James Park (Opus/NZTA), Traffic management coordinator Sonia Pollard (CCC), Communications co-ordinator Barry Stratton (NZTA), Dean Hurford (Opus/NZTA), Kevin Westeneng (SCIRT)

5 Strategic Routes Team corridor relief measures Prioritised building demolitions and/or make safe Prioritised road/bridge repairs Prioritised road re-openings Capacity improvements - signals, signs and markings Cycle route repairs and alternative cycle routes

10 Immediate losses of 10,000 (Christchurch), 100 (Selwyn) and 200 (Waimakariri) assumed. Household Changes

11 Earthquake Effects Estimating impacts on business Business Relocations Preliminary estimated landuse changes post-eq Pre Total=55,900 Post Total =30,900 (including 4,000 construction workers) CBD Fringe -50%* Pre=8,100 Post=4,900 CBD Outer -10%* Pre=25,100 Post=24,400 CBD Core -100%* Pre=22,700 Post = 1, months 11 % Reductions exclude Hospital and Construction Jobs Post-earthquake totals include influx of Construction workers assumed

12 Demand Change from 2011 (Pre-Quake) to 2011 (Post-Quake), red is traffic increases Earthquake Effects Change in Travel Demands Increased orbital movements Decreased radial, though observations suggest that these are returning, esp Lincoln, Blenheim, Riccarton Preliminary CTM results (April 2011) from estimated landuse changes post-eq 12

13 Demand Change from 2011 (Pre-Quake) to 2016 (Post-Quake), with no network restoration

14 14 Christchurch Roads of National Significance

15 Demand Change at 2016 (Post-quake Land-use) with Initial RoNS provision Western Corridor and CSM1 Difference between: And Land use: 2016 Post-Quake / Network: 2016 Initial RoNS Land use: 2016 Post-Quake / Network: 2016 Post-Quake

19 Early engagement with SRT Strategic Routes Team need to be notified of all significant work programmes and projects Liaison with all RCA's, CERA, SCIRT, contractors, utilities operators 12 Months notice of Annual work programmes (discuss possible implications, assessment required and opportunities to re-schedule works) 3 Months notice of forward work programme (quarterly liaison meeting or notification) 1 Monthly progress updates and forward TMP s All TMP s go through normal processes

21 Traffic Management Coordination to Keep Christchurch Moving Significant Moderate Potential significant delays/queues Impacts multiple Strategic Routes Has area wide or city wide effects Test all possible options to minimise delays Coordinate traffic management plans in area and re-schedule if neccesary Major communications required Finalise through TMP process Potential delays/queues Impacts Strategic Route Review traffic management plans Coordinate communications Finalise through TMP process Minor Minor and localised effects only Does not affect Strategic route Standard TMP process
