WEBVTT

00:00:00.836 --> 00:00:03.793
有啲人鍾意飲法國紅酒

00:00:04.302 --> 00:00:06.524
而有啲人鍾意打哥爾夫球

00:00:06.548 --> 00:00:08.187
或者埋頭睇書

00:00:08.729 --> 00:00:11.118
我平時最大嘅樂趣之一

00:00:11.118 --> 00:00:13.534
我必須承認有少少特別

00:00:13.946 --> 00:00:16.694
我冇辦法描述我有幾鍾意

00:00:16.708 --> 00:00:20.319
從飛機窗睇城巿

NOTE Paragraph

00:00:20.916 --> 00:00:23.911
有啲城市默默咁努力

00:00:23.935 --> 00:00:25.475
比如話杜塞爾多夫

00:00:25.499 --> 00:00:27.140
又或者路易斯維爾

00:00:27.780 --> 00:00:28.780
有啲城市

00:00:28.780 --> 00:00:31.437
投射出佢哋幾乎冇辦法承受嘅活力

00:00:31.437 --> 00:00:32.754
比如話紐約

00:00:32.778 --> 00:00:34.003
或者香港

00:00:34.524 --> 00:00:36.806
然後仲有巴黎

00:00:37.492 --> 00:00:39.204
或者伊斯坦布爾

00:00:39.228 --> 00:00:41.201
同埋佢哋充滿歷史印記嘅一面

NOTE Paragraph

00:00:42.108 --> 00:00:44.158
我將城市睇成生物

00:00:44.514 --> 00:00:46.982
當我從高空探索佢哋

00:00:47.006 --> 00:00:51.431
我鍾意搵建構空間嘅大馬路同高速公路

00:00:52.019 --> 00:00:53.495
尤其喺晚黑

00:00:53.519 --> 00:00:54.758
當果啲上落班嘅人

00:00:54.758 --> 00:00:58.908
令呢啲大馬路望起身非常璀璨

00:00:58.908 --> 00:01:03.195
城市嘅血管系統執行緊重要嘅任務

00:01:03.219 --> 00:01:04.429
就喺你眼前

00:01:05.569 --> 00:01:08.409
但係當我坐喺我部車入面

00:01:09.020 --> 00:01:12.312
日日駕駛一個半鐘頭上落班之後

00:01:12.336 --> 00:01:14.213
現實就好唔一樣啦

NOTE Paragraph

00:01:14.237 --> 00:01:15.291
（笑聲）

NOTE Paragraph

00:01:15.315 --> 00:01:16.473
乜都無辦法

00:01:16.497 --> 00:01:18.187
公共電台唔得

00:01:18.211 --> 00:01:19.370
播客唔得

NOTE Paragraph

00:01:19.394 --> 00:01:20.422
（笑聲）

00:01:20.446 --> 00:01:22.455
甚至連冥想都冇辦法

00:01:22.479 --> 00:01:24.094
令呢一段時間變得有意義

NOTE Paragraph

00:01:24.118 --> 00:01:25.727
（笑聲）

NOTE Paragraph

00:01:26.072 --> 00:01:27.226
唔覺得好可笑咩？

00:01:27.250 --> 00:01:31.707
我哋製造出時速可以達到 130 英里嘅車

00:01:31.731 --> 00:01:37.353
然後以 19 世紀馬車嘅速度嚟開？

NOTE Paragraph

00:01:37.377 --> 00:01:38.636
（笑聲）

NOTE Paragraph

00:01:38.660 --> 00:01:40.402
凈係喺美國

00:01:40.426 --> 00:01:45.820
2014 年，我哋就用咗296億個鐘上落班

00:01:46.281 --> 00:01:47.899
同樣嘅時間

00:01:47.923 --> 00:01:52.214
古埃及人可以起 26 個吉薩金字塔

NOTE Paragraph

00:01:52.238 --> 00:01:53.284
（笑聲）

NOTE Paragraph

00:01:53.308 --> 00:01:54.706
我哋喺一年時間就用咗咁多個鐘

00:01:54.730 --> 00:01:59.106
浪費大量嘅時間、能量同埋人類潜力

NOTE Paragraph

00:02:00.154 --> 00:02:01.331
幾十年嚟

00:02:01.355 --> 00:02:03.663
我哋應對塞車嘅措施都好簡單：

00:02:03.687 --> 00:02:06.728
起一條新路或者擴闊現有嘅路

00:02:07.198 --> 00:02:08.348
呢個措施好有效

00:02:08.372 --> 00:02:10.830
喺巴黎相當之有效

00:02:10.854 --> 00:02:13.944
巴黎拆咗幾百座歷史建築

00:02:13.968 --> 00:02:15.615
嚟起 85 英里

00:02:15.639 --> 00:02:17.920
方便運輸嘅林蔭大道

00:02:18.879 --> 00:02:21.119
呢個做法對宜家高速發展嘅新興城市

00:02:21.119 --> 00:02:22.549
依然好有效

00:02:22.549 --> 00:02:24.945
但係喺更多發展完善嘅市中心裡面

00:02:24.969 --> 00:02:28.899
大量嘅網絡擴張幾乎係唔可能嘅

00:02:28.923 --> 00:02:30.843
住房建築太密集

00:02:30.867 --> 00:02:32.840
房地產太貴

00:02:32.864 --> 00:02:34.924
同埋公共財政太脆弱

00:02:35.780 --> 00:02:39.385
我哋城市嘅血管系統塞住咗、病咗

00:02:39.409 --> 00:02:41.016
而我哋應該多多關注

NOTE Paragraph

00:02:41.040 --> 00:02:43.743
我哋目前嘅思考方式係唔掂嘅

00:02:44.172 --> 00:02:46.093
為咗令我哋嘅交通順暢

00:02:46.117 --> 00:02:48.468
我哋需要新嘅靈感源頭

NOTE Paragraph

00:02:50.187 --> 00:02:52.879
喺運輸業做咗16年之後

00:02:53.437 --> 00:02:55.002
當我同一個做生物科技嘅客人

00:02:55.002 --> 00:02:55.967
傾偈嘅時候

00:02:55.967 --> 00:02:57.622
靈感出現咗

00:02:57.622 --> 00:02:59.650
佢同我講佢嘅療程

00:02:59.674 --> 00:03:02.917
點利用血管系統裡面嘅某啲特性

00:03:03.582 --> 00:03:06.050
我心諗︰哇，我哋嘅血管系統

00:03:06.074 --> 00:03:09.150
即係體內所有嘅血管同動脈

00:03:09.174 --> 00:03:12.381
每一日都創造緊物流嘅奇跡

00:03:13.112 --> 00:03:15.270
就係呢一刻，我意識到

00:03:15.294 --> 00:03:20.067
生物學已經存在喺運輸業入面幾十億年

00:03:20.364 --> 00:03:22.728
血管系統試過無數解決方法

00:03:22.752 --> 00:03:26.051
嚟運送營養、氣體同埋蛋白質

00:03:26.532 --> 00:03:30.893
真係世界上最精密嘅運輸實驗室

NOTE Paragraph

00:03:31.326 --> 00:03:36.829
如果解決交通需求嘅方法
就喺我哋體內呢？

00:03:37.895 --> 00:03:39.160
我想知

00:03:39.184 --> 00:03:42.980
點解血液好平常咁喺血管流動

00:03:43.004 --> 00:03:46.596
但係我哋嘅城市就日日塞車？

00:03:46.990 --> 00:03:51.554
事實上你係睇緊兩個非常唔同嘅網絡

00:03:52.013 --> 00:03:53.832
唔知你有冇意識到

00:03:54.223 --> 00:03:58.920
我哋每個人體內都有六萬英里長嘅血管

00:03:58.944 --> 00:04:00.238
有六萬英里

00:04:00.262 --> 00:04:02.464
喺你嘅體內

00:04:02.498 --> 00:04:04.131
係地球圓周嘅 2.5 倍

00:04:04.860 --> 00:04:08.179
亦即係話我哋體內周圍都係血管

00:04:08.203 --> 00:04:10.230
唔只係喺我哋皮膚表層嘅下面

NOTE Paragraph

00:04:10.610 --> 00:04:12.819
但係當你望向我哋嘅城市

00:04:12.843 --> 00:04:15.941
冇錯，我哋係有地鐵系統

00:04:15.965 --> 00:04:18.381
有隧道同橋樑

00:04:18.405 --> 00:04:20.685
仲有天上嘅直升機

00:04:20.709 --> 00:04:24.768
但係大部分嘅交通都集中喺地面

00:04:24.792 --> 00:04:25.969
喺表層

00:04:26.450 --> 00:04:27.805
即係話

00:04:27.829 --> 00:04:32.208
我哋體內嘅血管系統係立體

00:04:32.232 --> 00:04:34.996
而市區運輸系統基本上係平面

00:04:35.881 --> 00:04:38.914
所以我哋應該將天空納入運輸系統

00:04:39.290 --> 00:04:41.855
如果我哋嘅平面飽和咗

00:04:41.879 --> 00:04:43.777
咁就將交通升高

NOTE Paragraph

00:04:44.174 --> 00:04:45.694
呢個概念嚟自中國

00:04:45.694 --> 00:04:48.594
巴士可以跨立係堵塞嘅車輛上面

00:04:48.694 --> 00:04:50.399
呢個概念令我哋大開眼界

00:04:50.423 --> 00:04:53.033
對於城巿入面嘅空間同移動

00:04:53.033 --> 00:04:54.544
有新嘅思考方式

00:04:54.714 --> 00:04:56.675
我哋可以行高啲

00:04:56.699 --> 00:04:58.518
將運輸系統懸掛

00:04:58.518 --> 00:05:01.148
就好似我哋嘅供電網咁

00:05:01.968 --> 00:05:04.495
特拉維夫同阿布扎比宜家討論緊

00:05:04.529 --> 00:05:08.841
測試呢種磁懸浮車艙嘅未來網絡

00:05:09.465 --> 00:05:12.361
我哋可以繼續攀爬，飛天

00:05:13.263 --> 00:05:15.190
事實上好似空中巴士呢種公司

00:05:15.214 --> 00:05:18.522
宜家認真咁研究市區空中的士

00:05:18.546 --> 00:05:19.919
講明咗一啲事

00:05:20.633 --> 00:05:25.501
飛天汽車終於從科幻

00:05:25.525 --> 00:05:28.214
轉移到吸引嘅商業範疇

00:05:28.238 --> 00:05:29.848
呢一刻好令人興奮

NOTE Paragraph

00:05:30.415 --> 00:05:33.044
所以起呢個 3D 運輸網絡

00:05:33.068 --> 00:05:38.386
係緩和並且解決塞車嘅方法之一

00:05:38.410 --> 00:05:39.820
但唔係唯一嘅方法

00:05:40.257 --> 00:05:41.875
我哋必須質疑

00:05:41.899 --> 00:05:44.338
我哋其他嘅根本性選擇

00:05:44.338 --> 00:05:46.278
比如話交通工具

00:05:46.278 --> 00:05:48.618
想象一下一個好熟悉嘅場景：

00:05:48.983 --> 00:05:51.116
你已經開咗 42 分鐘車

00:05:51.656 --> 00:05:54.379
你後面嘅兩個細路仔開始煩躁

00:05:54.899 --> 00:05:56.104
而你已經遲到

00:05:56.754 --> 00:05:59.019
見唔見到前面果部開得好慢嘅車？

00:05:59.474 --> 00:06:00.586
呢種事成日發生係你遲到嘅時候

00:06:00.586 --> 00:06:01.458
啱唔啱？

NOTE Paragraph

00:06:01.458 --> 00:06:02.451
（笑聲）

NOTE Paragraph

00:06:02.475 --> 00:06:04.638
果個司機搵緊停車位

00:06:05.193 --> 00:06:07.410
果度附近冇空位

00:06:07.434 --> 00:06:08.777
但係佢點知呢？

00:06:09.552 --> 00:06:13.772
估計大約 30% 嘅市區塞車問題

00:06:13.772 --> 00:06:16.217
係因為司機搵緊停車位

00:06:17.091 --> 00:06:18.965
見唔見到你身邊嘅 100 部車？

00:06:19.549 --> 00:06:22.160
其中 85 部車入面只有一個乘客

00:06:22.571 --> 00:06:26.791
呢 85 位司機可以坐滿一部倫敦紅巴士

00:06:27.339 --> 00:06:28.234
然後問題係

00:06:28.234 --> 00:06:29.514
如果空間係我哋急需嘅嘢

00:06:29.514 --> 00:06:31.228
點解仲要浪費？

00:06:31.228 --> 00:06:33.360
點解我哋要咁對待自己？

NOTE Paragraph

00:06:33.746 --> 00:06:35.700
生物學永遠唔會咁做

00:06:36.189 --> 00:06:39.236
我哋充分利用咗血管裡面嘅空間

00:06:39.722 --> 00:06:41.246
每一下心跳

00:06:41.270 --> 00:06:45.283
高血壓就壓迫幾百萬個紅血球

00:06:45.307 --> 00:06:47.425
進入龐大嘅氧氣火車裡面

00:06:47.449 --> 00:06:49.338
好快咁係我哋人體內流通

00:06:49.771 --> 00:06:53.701
而紅血球裡面嘅小空間亦冇浪費

00:06:54.357 --> 00:06:56.074
喺健康嘅情况下

00:06:56.098 --> 00:07:00.136
最少會用到 95% 嘅氧氣容量

00:07:00.494 --> 00:07:01.494
你能唔能夠想象

00:07:01.494 --> 00:07:03.379
如果城市裡面用嘅交通工具

00:07:03.379 --> 00:07:05.063
使用率有 95%

00:07:05.087 --> 00:07:07.545
將會有幾多額外空間攞嚟行路

00:07:07.545 --> 00:07:10.033
踩單車、同埋享受城市嘅魅力？

NOTE Paragraph

00:07:10.616 --> 00:07:14.129
血液之所以咁高效率

00:07:14.153 --> 00:07:17.254
係因為我哋嘅紅血球並唔係只用喺

00:07:17.278 --> 00:07:19.132
特定嘅器官同組織

00:07:19.497 --> 00:07:22.608
如果唔係，我哋嘅血管可能會塞車

00:07:22.632 --> 00:07:23.864
紅血球係共享嘅

00:07:23.888 --> 00:07:26.264
係我哋體內所有細胞共享嘅

00:07:26.737 --> 00:07:29.390
因為我哋嘅網絡咁龐大

00:07:29.414 --> 00:07:34.174
37 兆個細胞，每一個都運送氧氣

00:07:34.198 --> 00:07:35.727
啱啱好係需要嘅時候

NOTE Paragraph

00:07:36.253 --> 00:07:40.843
血液係一種既集體又獨立嘅傳輸方式

00:07:41.513 --> 00:07:43.057
但係對我哋嘅城市嚟講

00:07:43.081 --> 00:07:44.365
我哋塞住咗

00:07:44.389 --> 00:07:46.434
我哋塞喺無止境嘅辯論裡面

00:07:46.458 --> 00:07:49.295
辯論建立以車為中心嘅社會

00:07:49.295 --> 00:07:52.295
定建立係龐大嘅公共交通系統

00:07:52.295 --> 00:07:53.910
我覺得我哋應該更進一步

00:07:53.934 --> 00:07:55.277
我覺得我哋可以發明一啲交通工具

00:07:55.277 --> 00:07:58.277
結合車嘅方便

00:07:58.277 --> 00:08:00.594
同埋火車同巴士嘅高效率

00:08:01.459 --> 00:08:02.864
想象一下

00:08:02.888 --> 00:08:04.380
你同 1,200 名乘客一齊

00:08:04.430 --> 00:08:06.760
好舒服咁坐喺一部

00:08:06.810 --> 00:08:09.620
又快又流暢嘅巿區火車裡面

00:08:09.950 --> 00:08:11.637
城市火車嘅問題係

00:08:11.661 --> 00:08:16.056
喺到達最終目的地之前

00:08:16.080 --> 00:08:17.621
有時要停靠 5 次、10 次、15 次

NOTE Paragraph

00:08:18.421 --> 00:08:21.332
如果呢部火車係不需要停靠呢？

00:08:21.929 --> 00:08:23.198
當你喺路上嘅時候

00:08:23.222 --> 00:08:26.451
呢部火車嘅車廂可以動態分離

00:08:27.012 --> 00:08:29.494
變成快車、無人駕駛嘅巴士

00:08:29.518 --> 00:08:31.571
喺細啲嘅馬路上行駛

00:08:32.024 --> 00:08:33.925
所以完全唔使停靠

00:08:33.949 --> 00:08:35.536
亦唔會有漫長嘅轉車

00:08:35.560 --> 00:08:38.969
你宜家坐喺一部開往郊區嘅巴士上

00:08:39.647 --> 00:08:41.573
就嚟到嘅時候

00:08:41.597 --> 00:08:44.904
你坐嘅果部分會脫離

00:08:44.928 --> 00:08:47.878
自動將你送到目的地

00:08:48.523 --> 00:08:51.184
既集體又獨立

00:08:51.922 --> 00:08:54.681
呢個係共享、組合式

00:08:54.681 --> 00:08:57.101
無人駕駛嘅未來交通工具之一

NOTE Paragraph

00:08:57.681 --> 00:08:58.842
宜家……

00:08:59.217 --> 00:09:02.375
就好似喺城市行走，有無人機

00:09:02.399 --> 00:09:06.686
空中的士、組合式巴士同埋磁懸浮車艙

00:09:06.710 --> 00:09:08.161
都仲未夠神奇

00:09:09.062 --> 00:09:10.999
我覺得仲有另外一種力量喺度努力緊

00:09:11.023 --> 00:09:13.604
令巿區交通變得更有魅力

00:09:14.541 --> 00:09:16.130
你諗下

00:09:16.154 --> 00:09:21.160
宜家嘅無人駕駛車輛諗緊辦法

00:09:21.184 --> 00:09:24.214
進入由人製造、為人服務嘅
交通網絡裡面

00:09:24.626 --> 00:09:26.426
佢哋嘗試學習交通規則

00:09:26.426 --> 00:09:28.551
呢個仲算簡單

00:09:28.551 --> 00:09:30.460
更有挑戰性嘅係

00:09:30.484 --> 00:09:32.406
佢哋仲要應對人類嘅不可預測性

NOTE Paragraph

00:09:33.063 --> 00:09:34.063
但係當成個城市變成

00:09:34.063 --> 00:09:36.999
無人駕駛嘅時候會點？

00:09:36.999 --> 00:09:38.827
我哋仲需唔需要紅綠燈？

00:09:38.851 --> 00:09:40.447
仲需唔需要車道？

00:09:40.471 --> 00:09:41.970
速度限制呢？

00:09:42.563 --> 00:09:44.852
紅血球唔係喺車道上面流通嘅

00:09:45.402 --> 00:09:47.363
佢哋從來都唔會因為紅燈而停

00:09:47.387 --> 00:09:49.363
係第一批無人駕駛嘅城市裡面

00:09:49.387 --> 00:09:51.504
唔會有紅燈同埋車道

00:09:52.014 --> 00:09:55.087
當所有車都係無人駕駛而且連埋一齊

00:09:55.630 --> 00:09:59.195
一切都可以預測，反應時間都係最短

00:09:59.219 --> 00:10:01.133
無人駕駛車可以開得更加快

00:10:01.157 --> 00:10:04.094
可以採取任何合理嘅行為嚟加快速度

00:10:04.118 --> 00:10:05.735
或者加快旁邊其他車嘅速度

00:10:06.600 --> 00:10:09.275
車流會係可以透過使用動態

00:10:10.203 --> 00:10:13.235
不斷自我改善嘅規則系統控制

00:10:13.235 --> 00:10:16.386
代替死板嘅交通規則

00:10:18.468 --> 00:10:21.195
結果就係，奇怪嘅交通系統

00:10:21.219 --> 00:10:24.730
融合咗德國高速公路嘅快同穩

00:10:24.754 --> 00:10:28.054
同埋孟買十字路口嘅創意活力

NOTE Paragraph

00:10:28.695 --> 00:10:30.254
（笑聲）

NOTE Paragraph

00:10:30.278 --> 00:10:32.233
交通功能將會非常豐富

00:10:32.257 --> 00:10:34.698
會好似血液咁流動

00:10:34.722 --> 00:10:36.478
根據一個奇怪嘅悖論

00:10:36.502 --> 00:10:39.313
交通網絡越係自動化

00:10:39.337 --> 00:10:42.093
佢嘅流動就越統一而且充滿活力

NOTE Paragraph

00:10:43.075 --> 00:10:44.852
所以，冇錯

00:10:44.876 --> 00:10:45.876
生物學有嗮所有

00:10:45.876 --> 00:10:48.598
當代交通天才應該有嘅特性

00:10:48.598 --> 00:10:51.407
但呢個過程已經喺幾十億年前開始

00:10:51.431 --> 00:10:54.433
而且經歷咗好多次嘅反覆同變異

00:10:54.892 --> 00:10:56.559
我哋唔可以等幾十億年

00:10:56.559 --> 00:10:58.979
逐漸發展運輸系統

00:10:58.979 --> 00:11:00.807
宜家我哋有夢想

00:11:00.831 --> 00:11:02.123
有概念

00:11:02.147 --> 00:11:04.453
有技術

00:11:04.477 --> 00:11:07.327
嚟起一個 3D 運輸網絡

00:11:07.351 --> 00:11:09.066
發明新嘅交通工具

00:11:09.090 --> 00:11:10.714
同改變我哋城市嘅流動

NOTE Paragraph

00:11:11.109 --> 00:11:12.264
一起行動啦

NOTE Paragraph

00:11:12.288 --> 00:11:13.452
多謝

NOTE Paragraph

00:11:13.476 --> 00:11:16.309
（鼓掌）
