New Details on the Direct Taipei-Yilan Rail Line

From the MOTC's Railway Reconstruction Bureau
The Ministry of Transportation's Railway Reconstruction Bureau recently held a public meeting about possible routes for a more direct railway line between Taipei and Yilan.  There are two proposals: a shorter route that would roughly parallel National Highway 5, and a longer one that would cross under Pingxi and meet the current Yilan Line at Shuangxi, before turning south and merging with the Yilan Line just north of Daxi.  This route would include a station at Shuangxi to allow transfers to the Yilan Line.  Because the Taipei City government is opposed to the first option because it would cross through the Feicui Reservoir watershed, the second, longer route is more likely to be chosen.  This route would cost NT$49.1 billion (US$1.6 billion) to construct, an average of US$30.2 million a kilometer.  Taroko or Puyuma express trains would be 18 minutes faster, taking as little as 45 minutes to get from Taipei to Jiaoxi, while conventional Tse-Chiang trains could save 38 minutes, shortening trips to as little as 50 minutes.  Once the new line is complete the old line would remain in service.  The earliest possible date for completion is 2031, and construction is expected to take 9 years.
Support for the line is far from unanimous.  It would still cross through reservoir catchment areas, and near many old mine shafts.  Environmentalists worry that it will damage relatively untouched ecosystems.  At least one legislator thinks 18 minutes isn't worth nearly NT$50 billion, and that money would be better spent upgrading the TRA.
Some of these fears are certainly overblown- presumably this wouldn't be the world's first rail line built around old mine shafts.  The key questions should be will the environmental benefit of fewer people driving be worth the damage caused by its construction, and will the line earn enough money to justify its cost.  Though this line might save "only" 18 minutes, that should be enough to draw many people out of cars and planes and onto trains, boosting the TRA's revenue and cutting down carbon dioxide emissions.  It could also obviate the need for future road and highway expansion.  There's no way of knowing unless the government does a more complete study.

Taipei MRT Ridership by Station in 2013

Below is a list of the most heavily used MRT stations in Taipei in 2013, by the total number of boardings and alightings at each station.  The data comes from the Taipei Department of Transportation.

StationLineExits+Entrances
Taipei Main StationDanshui, Bannan114,065,000
Taipei City HallBannan47,641,000
XimenBannan, Xiaonanmen43,468,000
Zhongxiao FuxingBannan, Wenhu38,390,000
Zhongxiao DunhuaBannan29,524,000
DanshuiDanshui29,037,000
XinpuBannan26,768,000
BanqiaoBannan25,420,000
JiantanDanshui25,387,000
DingxiZhonghe-Xinlu22,743,000

The top seven stations remain the same as in 2012, but there's been some movement among the bottom three.  First, Banqiao continued to gain users, and overtook Jiantan to become the 7th most popular station in the system, just shy of Xinpu, which saw its ridership fall slightly.  Banqiao remains the only station opened after 2001 to be among the top 10.  In addition, Dingxi replaced Zhongshan as the 10th most popular station, presumably boosted by the Zhonghe Line's increased frequency and new direct connection to the Xinzhuang Line.  Dingxi is the 4th station in New Taipei to make the list, and the first on the Zhonghe-Xinlu Line.  Since the Dingxi area has little to attract people from outside Yonghe, Dingxi is almost certainly an origin station rather than a destination, suggesting that the Zhonghe-Xinlu Line feeds passengers into other parts of the MRT system rather than take them directly to their destination.  
As in pervious years, the Bannan Line was the dominant line in the MRT system, with 7 of the top ten stations and all of the top 5.  The Danshui Line remains the second most important, even though its share of the top ten dropped from 4 stations to 3.  The Zhonghe-Xinlu Line just broke into the top ten with one station, while the Wenhu Line only made it onto the list through its transfer station with the Bannan Line.
Below are the 10 least-used stations for 2013:

StationLineExits+Entrances
Nangang Software ParkWenhu789,000
Wanfang CommunityWenhu1,363,000
XiaobitanXiaobitan1,413,000
Dahu ParkWenhu1,900,000
ZhongyiDanshui1,990,000

SanchongZhonghe-Xinlu2,202,000
FuxinggangDanshui2,455,000
LinguangWenhu2,603,000

As with the top 10, the bottom 10 are mostly the same as last year, with the exception of Touqianzhuang being replaced by Linguang.  This leaves the Wenhu Line dominating the list with 5 stations, while the Danshui and Zhonghe-Xinlu Lines are tied for second with 2 each.
Below are the average number of riders passing through all the stations on each line.  Average ridership for all stations grew by 4.8% compared to 2012.

Bannan20,690,0002.0%
Danshui/Xindian13,596,000N/A
Xindian11,053,0003.2%

Wenhu5,956,0002.2%
Neihu5,152,0006.3%
Muzha6,759,000-0.7%

Unsurprisingly, the Bannan Line was the most heavily used line, followed by the Danshui-Xindian Line, the Zhonghe-Xinlu Line and finally the Wenhu Line.  This reflects how many stations each line has in the top ten.  Ridership was most uneven on the Zhonghe-Xinlu Line, with the Zhonghe Line having the heaviest ridership, the trunk section of the Xinzhuang Line seeing mediocre ridership and the Luzhou and especially the Xinzhuang branches having very low ridership. The Xinzhuang Branch was the second least-used section of the MRT, followed only by the Muzha section of the Wenhu Line.
Growth was very uneven in 2013.  The largest gains in ridership were on the newest lines, with the central section of the Xinzhuang Line between Zhongxiao Xinsheng and Daqiaotou growing faster than any other section of the MRT, and Songjiang Nanjing gaining more users than any other station, followed by Xingtian Temple.  This was presumably the result of the improved connection to the Zhonghe Line, though some of the increase may also have been caused by people adjusting their travel habits to take advantage of the new line- for example, people may be more willing to take jobs near the Xinzhuang Line that they were before.
The Zhonghe Line saw the second-largest gains after the trunk section of the Xinzhuang Line, presumably from increased frequency and the faster connection to the Xinzhuang Line and east Taipei.  However, the increase was less than half that of the Xinzhuang trunk line, suggesting that the Xinzhuang Line gained more from the new connection.  The Xinzhuang and Luzhou branches also gained quite a bit of ridership compared to 2012, presumably mostly from people adjusting to the new lines.
The Wenhu Line also saw uneven growth, with the Neihu section growing faster than the system average while the Muzha section losing passengers, especially in its central Taipei section.  Even with this decline- which follows a decline last year- the Muzha Line still has much higher ridership than it did before the Neihu extension opened.
Finally, although it doesn't appear on the above chart, the central section of the Danshui Line (that is, from Chiang Kai-shek Memorial Hall to Shuanglian) also lost ridership.  Part of this may have been caused by Zhonghe and Xindian Line passengers switching to the Xinzhuang Line to get to central and eastern Zhongshan District rather than transferring to buses at Zhongshan, Shuanglian or Minquan West Rd. stations, though the decline at NTU Hospital and Chiang Kai-shek Memorial Hall suggest it may be caused by other factors.
Overall, trends in 2013 were positive: newer, lesser used parts of the MRT gained ridership, which balanced out losses in more heavily used sections.  However, ridership remains very uneven, with the Bannan Line connecting to far more destinations than any other line.  To even out ridership Taipei should focus on developing destinations near central areas along less heavily used sections of the MRT.  For example, developing Minquan West Rd. as a destination would attract more riders from the underused Xinzhuang and Luzhou branches, as well as from the not especially crowded Xinzhuang trunk and northern Danshui Line.

Illegal Bicycle Parking Near MRT Stations

Usually the biggest annoyance for pedestrians in Taiwan is scooters parked on sidewalks, but according to the Liberty Times bicycles are also becoming an issue.  While remembering to take any Taiwanese newspaper's claims with a grain of salt, this reflects a pattern in Taipei City's promotion of cycling, where cyclists are permitted to take space from pedestrians but rarely from cars and scooters (Xinyi Rd. is an exception to this, with the removal of scooter parking providing space for cycling).  This discourages walking, the most environmentally friendly form of transport (as well as the safest and healthiest), while leaving drivers with a disproportionate amount of street space.  Of course, Taipei's government can't wholly be held responsible for illegal bicycle parking, but the police admission to only targeting illegally parked cyclists near the Gongguan and Technology Building MRT stations shows some culpability.  Cycling should definitely be encouraged, but more cycling will require taking space from other modes of transportation- and that mode should be automobiles, not pedestrians.

Taichung Passes Limited Ban on Fuel-Burning Scooters

Taichung is probably the most difficult Taiwanese city to get around without a motor vehicle: it doesn't yet have any mass transit rail, its bus system is difficult to use, and sidewalks are often nonexistent even on busy streets.  So it's very surprising to see that Taichung, more or less out of the blue, has proposed banning its most popular form of transportation: gasoline-burning scooters- albeit only in certain to be determined areas, and not until 2021.  Areas that might be considered are the Shuinan Trade Zone and the city's pedestrian zones (they aren't banned in pedestrian zones already??).  The measure is part of a law to lower Taichung's carbon emissions, and originally was only going to apply to scooters with two-stroke engines before it was expanded.  The city also plans on offering subsidies to encourage people to switch to electric scooters.
Needless to say, the new law caused a wave of online anger from scooter drivers who feel that the Taichung City Government is "oppressing" them.  While I believe the complaints are overblown and think lowering scooter usage is a good thing, I also think a ban is a bad way to achieve this goal, given the backlash it caused.  Perhaps a carbon tax or fuel tax that applied to cars as well as scooters would attract less opposition and be easier to defend.  Also, lack of public consultation before this law was passed helped ensure it would meet opposition from people who felt their interests were not being taken into account at all.
Hopefully the furor will calm down, the ban will be enacted and no one will care much because Taichung will have a much better mass transit system by then, and regardless the ban will only effect a small area.  By bungling this, however, Jason Hu has made it much more likely that Taichung's next mayor will overturn it and do little to make Taichung hospitable for walking and mass transit.

Tainan Proposes Monorail System

Tainan has proposed building a monorail, which it calls a "light metro" (輕量捷運), and which would run from near the intersection of Xiaodong and Zhonghua Roads to Anping and connect to planned bus transfer stations.  Tainan's Transportation Commissioner Zhang Zhengyuan (張政源) claims that a monorail would be more convenient than a light rail system, could be privately run, would cost half as much as light rail (?!) and, since it could be built above medians, construction wouldn't disrupt traffic.  He also claimed that travel times could be reduced to less than 10 minutes.  The city government hopes to conduct a viability study next year.
While I'm glad Tainan is taking some tentative steps to building a rail system, I can't help but be skeptical about Tainan's choice of mode when they claim that an elevated monorail would be cheaper than an at-grade light rail system.  Of course, it will be a long time before we know if anything will come of this at all.

Taiwan's Transportation Mode Share

The chart below shows what kinds of transport Taiwanese used to travel in 2012 for trips for a specific purpose that exceeded 500 meters, according to the same Ministry of Transportation survey I referenced when I looked at why Taiwanese don't take mass transit.

Mode % in 2012 % change vs. 2009
Private vehicle 72.6% -1.0%
Mass transit 15.0% +1.6%
Walking or cycling 12.4% -0.7%

And this is the mode share for commuting to either work or school:

Mode% in 2012% change vs. 2009
Private vehicle74.1%+0.6%
Mass transit18.3%+1.2%
Walking or cycling7.7%-1.7%

Unsurprisingly, private motorized transport- i.e., cars or scooters- are dominant.  However, this rate is lower than what I've heard of in developed countries (I think 90-95% in the US, 80% in Japan, though I haven't been able to find a good source for comparable data).  My guess is Taiwan's relatively low rate of private vehicle trips is the result of its density, and maybe from its lower average income.
While mass transit is growing more popular, a more unfortunate trend is a decrease in walking and cycling, especially to get to work or school.  I can't say why this is occurring, though it certainly suggests Taiwan's terrible sidewalks aren't improving much.
Below are the percentages for each specific form of transportation, with growth rates since 2011.

Mode % in 2012, all trips change vs. 2011 % in 2012, commutes change vs. 2011
Scooter 47.8% -0.7% 49.4% +0.1%
Car 23.2% -0.9% 22.7% -0.9%
Bus 9.0% +0.8% 11.5% +0.7%
Walking 7.2% +0.5% 3.9% 0
Bicycle 5.2% +0.3% 3.8% +0.5%
MRT 3.9% 0 4.8% -0.2%
Train 1.3% +0.1% 1.6% +0.1%
Taxi 0.6% -0.1% 0.2% 0
HSR 0.1% -0.1% n/a n/a

Also unsurprisingly, scooters are by far the favorite mode in Taiwan, though they don't quite account for half of all trips.  For mass transit, buses (which include highway and freeway coaches as well as city buses) are the most popular form, which is also not unexpected given Taiwan's limited rail coverage outside the Taipei Basin.  More surprising to me is the popularity of cycling, despite the poor cycling conditions in most Taiwanese cities.
In contrast to the period between 2009 and 2012, trends between 2011 and 2012 have mostly been positive- according to the report's introduction the 2012 was the first year that public transit and non-motorized transit both gained mode share.  The MRT was an exception to this trend, however, and didn't gain mode share despite the opening of the Xinzhuang Line- in fact, it lost a little for commutes.  Buses have been doing pretty well, however.

Taipei MRT Will Implement Different Routes After 11PM

If you pay attention to the posters in Taipei's MRT, you've probably noticed that the MRT's routing will be rearranged when the Xinyi Line opens sometime over the next month.  Specifically, the current Beitou-Taipower Building line will separate from the Danshui-Xindian Line at Chiang Kai-shek Memorial Hall and run along the new Xinyi Line, while the Xiaonanmen Line will be extended from Chiang Kai-shek Memorial Hall south to Taipower Building.  The routing in the MRT's original plan was a bit simpler, with the Xiaonanmen and Xindian Lines becoming one line, while the Danshui Line would be extended along the Xinyi Line.  This routing would have let the Xinyi Line run at full capacity, but it would also force Xindian Line passengers bound for stations on the Danshui Line to transfer, so the more complicated routing was chosen.
Now the MRT has announced that the Xinyi Line's route will change after 11PM.  To avoid having too many trains traveling on the elevated section of the Danshui Line and disturbing nearby residents, after 11 the Xinyi Line will terminate at Taipei Main Station.  The idea (I think) is that both the Xinyi Line and the whole of the Danshui-Xindian Line will run at 12 minute headways, but if they merged the headways would shrink to 6 minutes.
If this is the case, it means that once the Xinyi Line opens, service on the Danshui Line will actually be worse than it is now.  Now the section of the Danshui Line between Taipower Building and Beitou has 6 minute headways after 11PM, with this new routing headways will go up to 12 minutes- not a small difference.  Moreover, having two different routings is confusing- navigating a mass transit system should be as intuitive as possible; having two routings for different times of day will require riders to pay extra attention.  While I'm usually sympathetic to quality of life issues, it does strike me as a double standard: the MRT is very sensitive to noise complaints despite not being especially loud, but neither the Taipei nor the New Taipei governments seem interested in quieting down scooters, and New Taipei sometimes even does road construction late at night to avoid disrupting traffic.  Furthermore, there has been a rail line along the same route as the Danshui Line for nearly 100 years now, so it is worth asking why people who are bothered by the sound of trains moved there in the first place.
