City Speak XI - Is transport the solution or the enemy? Pascal Dupont of Alstom

Published on

Development and transport are closely related, but how do we connect the dots and guarantee a livable city for future generations?

Lifting the moratorium in Mid-levels, reducing the threshold for redevelopment and the constant pressure to increase density are all choking the older parts of Hong Kong with more traffic and roadside air pollution.

How do we deal with the increased traffic on new roads to the Mainland? How many more roads are we planning to build on our waterfront? Is there too much public transport clogging up our roads? Is replacing pedestrian crossings with subways and footbridges a good thing?

What plans are there for environmentally friendly transport and aesthetically more pleasing transport infrastructure in Hong Kong? Where are the hopes for making our city more pedestrian-friendly? Can new engine technology solve our problems? Could electronic road pricing help? Will the new rail lines be enough? Do we have a sustainable (transport) plan for our city?

Planners, engineers, academics and officials will discuss whether transport is our solution or our enemy.

Designing Hong Kong is a not-for-profit organisation focused on sustainable urban planning. See: www.designinghongkong.com

    6. 6. Commitment on sustainable mobility, thanks to new technologies Less noise and vibration emissions Energy saving solutions Less particles emissions
    7. 7. Development of new technologies: focus on power supply Why alternative power supply solutions? Traditional Power collection is via an Overhead Contact Wire (OCW), which necessitates a dedicated unsightly infrastructure. Removal of Urban Clutter Cities with historic center and buildings wanted an alternative to the OCW to eliminate the “clutter” created by the tram infrastructure.
    8. 8. <ul><li>Preserve urban environment </li></ul><ul><li>To facilitate access in narrow streets, facade renovation, … </li></ul>Development of new technologies: focus on power supply
    9. 9. <ul><li>Two main types of Alternate Solutions were developed : </li></ul><ul><ul><li>Full performance solutions (Alternate Power Supply or APS) : </li></ul></ul><ul><ul><ul><li>Rely on a wayside infrastructure to provide power to the vehicle </li></ul></ul></ul><ul><ul><ul><li>Need an interface between the vehicle and the wayside </li></ul></ul></ul><ul><ul><li>Limited performances solutions (On Board Energy Storage Systems or OBESS) that mix : </li></ul></ul><ul><ul><ul><li>A standard or alternate full performance infrastructure and </li></ul></ul></ul><ul><ul><ul><li>One or more dedicated on-board energy storage system(s) </li></ul></ul></ul>Development of new technologies: focus on power supply
    10. 10. Impact on the landscape, thanks to new technologies 1 - Ground level power supply via a 3 rd rail embedded in the tracks (APS)

    12. 12. Development of new technologies: APS in Bordeaux Facilitates road crossings and emergency service access Facilitates maintenance of city equipment Offers a total safety to pedestrians and road users
