‘What’s this got to do with transit in Metro Vancouver?’ you might be asking. Well, it’s a trial of a new technology that does actually have potential impact here.
Network Rail and its partners believe battery-powered trains could be used to bridge gaps in otherwise electrified parts of the network or be used on branch lines where it would not be cost effective to install overhead electrification equipment,
You can read the entire press release, if you are interested. A couple of important bits of information are missing: the weight of batteries and what they do to the power consumption of the train when it is running under the wires. The second bit there is probably one of the key determinants of whether this project goes on to production. There are many prototype tests: many of them have short lives or look very different by the time they get into production.
The technology is the interesting bit, because it does not necessarily need to be confined to trains. Vancouver has an extensive network of electric trolleybuses, but the wires do not always extend to useful destinations. It is very expensive to construct the overhead (back in 2004 I used to use the figure of $1m per kilometre for plain track – more for “special works” like switches and diamonds). So to add enough wire to get trolleybuses from say 41st at Crown to UBC is cost prohibitive.
The “new” trolleybuses – actually entering service at the end of 2006 – have much better batteries than the previous generation, but even so can only run at low speed and limited distances. And someone has to be stationed at each end of the gap to do the pole pulling. So battery power is for short distances and for temporary disruptions. Routes like the #7 Dunbar – Nanaimo have been running diesel buses under wires most of the way for at least a year by my observation. This new technology could see faster, longer operation on battery power for longer distances. This would both reduce the use of diesel – a worthy aim in itself – and cut costs. As long as someone comes up with a automated pole puller. Routes like the #9 could actually terminate somewhere useful, like Brentwood Mall, instead of the traditional loop at the city boundary. The #41 could run out to UBC electrically and use the wires for most of the route.
This is probably more likely than seeing CMBC put poles on hybrid buses to achieve the same objectives.

The draconian changes in drive driving rules in BC have worked to reduce collisions and casualties. No mention is made of why this change in legislation was controversial in this UBC study, so it does not come across as an evenhanded or even objective assessment of the policy change. Were the fears of the restaurant/pub operators justified? Are there any civil liberties concerns about the presumption of innocence lost at the “sobriety checkpoint” or the absence of due process when the police impose penalties without judicial oversight? Or is the unspoken rule any life saved is worth any cost?
There’s a very entertaining piece on the Port Mann Bridge by Neil Salmond on Strong Towns. It is all about what people do when faced with a choice between a fast, tolled route and a slower, untolled route. Or rather, what they say they will do. Apparently in Ohio drivers said they would drive out of their way to avoid a toll. Which, of course, is exactly what they are doing here: driving over the Patullo instead of the Port Mann. Even though the extra cost in gas alone is often going to be about the same as the toll, as demonstrated by a neat little gizmo put together by Todd Littman and the Sun. There’s also the fact that traffic forecasts in general seem to have made a fundamental error by simply extrapolating from the past. Just like steering a ship by staring at the wake, this method has some fairly obvious shortcomings. When circumstances change, so should expectations.
This blog has often berated transportation models – and modellers – for the shortcomings of the standard models. This particular issue is one that is often key to making decisions about choices for the future. How do you assess the willingness of people to choose a new route or mode which is currently not available? Two methods are in use: Revealed Preference (RP) and Stated Preference (SP).
The first one, RP, makes some generalizations about trip behaviour as a combination of time and money known as “generalized cost”. Data is collected about trip making and this is examined in terms of the trips made and the way they get distributed between routes and modes. This gets quite sophisticated as we know that travel time is not valued by users the same way in different modes. People prefer to be moving rather than waiting, and prefer to be seated and in vehicles under most sets of circumstances. So the values ascribed to time are different: people who are stuck in traffic or waiting for a bus are conscious of wasting time. People riding comfortably as passengers on public transport can use that time to do other things – read, use their cell phones and so on. With enough data about trip making on different routes and modes, it is possible to extrapolate what the new route/mode will be worth to its users in terms of time savings or greater comfort and convenience. It’s not hard, for instance, to compare High Speed Trains to airlines for city pairs and come up with a general rule that shows the threshold at which one will be preferred over the other. RP is only reliable for as long as the values assigned to the parameters do not change between the time the data was collected and the new project opens.
SP uses consumer surveys to get people to consider alternatives and tell the surveyor which one they prefer. It is widely used for all kinds of decision making – the appeal of new products and services, or even political preferences. And again it can get quite sophisticated in getting people to make comparisons and choices which are largely conjectures based on synthetic alternatives. And has a varied track record in accuracy of forecasting what choices get made in the real situations. In a region where there were no road tolls, it is quite surprising to me that the reported response to tolls for a bridge in Ohio were so negative. When people who used the free Albion Ferry were asked if they would be willing to pay a toll for a bridge, they said yes. And given the multiple sailing waits experienced at peak periods, the value they put on their time could also be measured in terms of the length of the trips they would otherwise have to make – crossing the old, congested Port Mann or the much more remote Mission Bridge. In any SP survey, people want to impress the surveyor with their rationality and decision making ability. In good ones, this well known issue is taken into account.
The traffic forecasts for the new Golden Ears Bridge were wildly optimistic. Traffic has so far failed to meet the expectations of the bridge builder/operator. A similar mistake was made with the Port Mann. And this being BC where we design P3 projects to shift money from the pockets of the public to private sector companies, we now pay through taxes for these errors. The bridge builder/operator faces no revenue risk.
In the case of the Port Mann there was already a good reason to doubt the traffic forecast. There was no bus service over the old bridge. It would have been easy to provide one, that would avoid the congestion of the bridge approaches by using bus lanes on the shoulders of the freeway. The 555 could have been running years ago – but that was avoided as it would have reduced the perceived “need” for freeway widening. And actually much potential new transit traffic could also have been won by running a direct bus between Surrey and Coquitlam instead of relying on an inconvenient, out of the way combination of existing SkyTrain and bus routes.
There has been a secular change in perceptions of the value of time and willingness to pay tolls that has not been taken into account by the forecasters. And that is that real personal incomes have been stagnant or declining for a long period of time. Moreover, the expectation that things will get better in the future – which seemed common for most of the post war period – has evaporated. Tax cuts have benefitted the wealthy disproportionately, since they have been replaced by all sorts of fees and charges which are levelled instead: they are applied with little or no consideration of ability to pay. The toll across the Port Mann Bridge is the same for the office cleaner and the CEO.
The other thing that has to be noted is the reliability of the data that is being collected. I have observed many times how this region collects far less travel data in terms of sample size than other cities: and this is orders of magnitude difference. But some of the most reliable data on trip making came from the census – at least for the journey to work mode choice over a very long time scale.
And then there is this
“The workplace has been overwhelmed by a mad, Kafkaesque infrastructure of assessments, monitoring, measuring, surveillance and audits, centrally directed and rigidly planned, whose purpose is to reward the winners and punish the losers. It destroys autonomy, enterprise, innovation and loyalty, and breeds frustration, envy and fear. Through a magnificent paradox, it has led to the revival of a grand old Soviet tradition known in Russian as tufta. It means falsification of statistics to meet the diktats of unaccountable power.”
This is the third, and final, instalment on my trip to Italy. And, as is common to blogs, it’s backwards, in that Rome is where our trip began.
On the way from the gate where we got off the plane, to the baggage carousel, there were all kinds of the usual retail opportunities that airports offer, and, indeed, depend upon. One of them was for the mobile phone company TIM, that internet research had shown to offer the best value for what I wanted. I bought a SIM card for my smart phone. It cost me 30€ ($46.87) of which about half was prepaid for calls, and the rest for 2G of high speed data (and unlimited low speed thereafter) and unlimited texts for the month. I think. The clerk’s English was barely adequate and all the documentation is, of course, is Italian. I was given documents to sign, and I though I was saying I did NOT want adverts by text. But it was the reverse. I got a daily barrage of incomprehensible offers by text from TIM the whole month. But now I was not dependent on wifi, and could access the internet anywhere. My phone also has Word Lens that is supposed to translate signs and stuff, and was almost entirely useless. I needed something to translate the translations. More than once I was glad of the data link to access Google Maps and sort out not just where we were but what direction we ought to head off in. It also meant that when I booked our trip to Venice, all I had to do was show the conductor on the trains the automated text message the FS system had sent me.
We were picked up from the airport by prior arrangement, and the journey into Rome was one of the scariest experiences I have had in a motor vehicle short of actually being in a collision. Afterwards we solemnly abandoned any thought of renting a car in Italy.
This is on the street where we rented an apartment. This car is not pulling out of a side street. It is parked. It is not unusual to see cars parked on the corner. They more usually park at an angle. The corner is usually the only place where there is a space to park. As pedestrians, we found that we were always taking what in a Canadian context would be very risky activity. If you wait at the curb, cars do not stop. You have to step into the traffic to show you are serious about crossing. Even then, motorcycles and scooters will simply weave around you as you cross. Fortunately many roads are narrow and often parked up on both sides. Most urban areas have one way streets, which result in much faster speeds.
Testaccio used to be part of the ancient Roman port facilities. It was redeveloped at the end of the 19th century as an industrial area with workers’ housing, and hosted the city’s slaughterhouse.
The river was prone to flooding, and the embankment process greatly reduced access to the waterside. Look at the height of the embankment and imagine that imposed on the Richmond dykes: or the waterfronts of Vancouver. Rome had to face floods every spring as it is surrounded by mountains – as we are. The rich lived on the hills: the ghetto regularly got flooded. That changed at the end of the nineteenth century for them. I suspect that it will have to change for us too, and in much shorter order than we are currently contemplating.
Trastevere, on the other side of the Tiber, has this two way cycle and pedestrian trail. I was lucky to be able to catch a cyclist actually using it. The Lonely Planet Guide has this to say about cycling “The centre of Rome doesn’t lend itself to cycling: there are steep hills, treacherous cobbled roads and the traffic is terrible.”
We saw several of these stations, but never any bikes. The only information I can find on line is entirely negative. There were no bikes in 2011 either. Lonely Planet does not mention bikesharing.
Ancient Rome is still in the centre of the City and most is unrestored ruins. This is the Forum – a view taken from Il Vittoriano. What is very noticeable about this view of the Eternal City is the amount of tree canopy, and the absence of modern high rise buildings.
There is a connected network of these streets across the Centro Storico.
I would like to see greater use of these barriers to car use in more cities. Robson St might be a suitable candidate, with trolleybus activation of barriers/signals.
Our neighbourhood had seen some traffic calming with this protected bike lane, and bumpouts for pedestrian crossings. Though you will note the pedestrian taking the more direct, diagonal route across the intersection. I did not actually see anyone use the bike lane, but I admire the vertical stanchions along the curb to prevent any danger of dooring.
There are many famous public spaces in Rome. Below is Piazza Navona – which was at that time the subject of some dispute between the authorities and the artists who rely on the tourists for their living.
Others are very impressive spaces, but seem to serve very little actual purpose. Or perhaps had one once that has now been lost.
This is Piazza del Popolo, once the site of public executions. At least they managed to keep it clear of traffic unlike the similar Place de la Concorde in Paris.
We did use the two line underground Metro. There is a third line now under construction, but progress is slow possibly due to the huge haul of archaeological material uncovered whenever you dig anywhere in Rome. It was reliable in some of the worst traffic disruptions, but not actually pleasant to use due to the crowding and the persistent presence of piano accordion players – some very young children. Begging – and demanding money with menaces at railway stations – is a real problem. We prefer surface travel, but one trip on Tram Number 3 from Piramide (near our apartment) to the Modern Art Gallery at the other end of the line took all morning! Trams do have some exclusive rights of way – but they often have to share them with buses and taxis and seem to have no ability to affect traffic signals.
There are two “albums” on flickr of public transport in general and trams in particular. Rome used to have an extensive tram network, but unlike other cities never abandoned it completely and has upgraded some lines in recent years with modern low floor articulated cars and reserved rights of way. Route 8 through Trastevere is one the better efforts. Our local service, route 3 along Marmorata, was curtailed during our stay due to track maintenance. We did best by choosing some of the designated express bus routes, which simply stop less often than regular services, rather like the B Line. Bus stops in Rome have very detailed information on them about services – but rarely have real time information. And the sale of bus maps is a commercial activity, not a public service. In the event of service disruptions, having a smart phone was no help as no information was available in English.
We did a lot of walking in Rome. There are lots of parks – Villa Borghese for instance, which is no longer an actual villa just its gardens. And we were next to one of the nicer neighbourhoods, Aventino, sort of a Roman Shaughnessy. So we saw a lot of a relatively small area, and not very much of the rest of the city, apart from one trip out of town to Ostia Antica (fantastic) – and on a our return an overnight stay in Fiumicino, which is not really worth visiting if it were not for the airport. The biggest issue was the tourists. Many more people are travelling these days, especially those from Eastern Europe who were once forbidden to travel but can now afford to do so. They all want to go to the same places, so the Spanish Steps, Trevi Fountain and Mouth of Truth are beseiged all day. Rome of course still attracts pilgrims. If you are not one of those avoid the Vatican on Thursday mornings when the Pope addresses the faithful in St Peter’s Square and the Colosseum on Mondays when it is one of the few sites that is open. And if you have the guide book and it promises you “secrets” you can bet your life every other tourist has the same guidebook in their own language and is headed the same way. How else to explain the line up to peek through the keyhole of a locked door on a monastery – to get as glimpse of the dome of St Peters, more easily seen from a park a few metres away?
We are leaving here tomorrow. It is a shame to have to say this, but I am actually glad to be going home. Our landlady in Florence told us that there was no point in staying for two weeks, there was not enough to keep us here. We have been in Venice last weekend largely as a result of this advice. We fell in love with Venice, and would have liked to have been able to stay longer. The expense alone was enough to deter that thought. If we could have got back to Vancouver from there … well anyway. Let me tell you about today, which is all about the sort of issues that get discussed on this blog all the time.
Last weekend, on Saturday, before our departure for Venice next morning, we took the advice of our Lonely Planet guide and decided to “get out of town”. Fiesole is a beautiful Tuscan hill village with stunning views and amazing archaeology. You can get there on a #7 bus, from Piazza San Marco within the 90 minute validity of a single ride. So tram ride ride from the apartment, walk across the Centro Storico, and up the hill we go, with a bus full of American art students. When we get to the village square – where the #7 turns round and goes back down the hill – there is a sign on the bus stop. Something obviously rushed out at the last minute on the office printer. No service on the #7 after 15:00 because of a road race – the 100km super marathon – a big deal – through Fiesole which means road closures and who knows when regular bus service can be restored. We saw the view – stunning – had lunch – ordinary but twice the price because of the view – and then caught the next bus back to town in case we got stuck and missed our train to Venice in the morning.
Today we tried again. Fiesole deserved a second chance, if only for its archaeology. Not just Etruscans and Romans but Lombards too. The bus stop for the #7 was beseiged. Local buses could not get near because of a flood of tour buses. In Livorno a massive cruise ship had landed, and tipped off its human cargo onto fleets of coaches full of punters sold on the idea of seeing Michaelangelo’s “David” for real. They get to see Florence in the morning and Pisa in the afternoon (or vice versa). The #7 bus stand is close to the Academy where this version (the real, authentic, actual statue as seen on tea towels and t shirts) could be seen. If you are waiting for a #7 local bus and many tour buses occupy the space where your expected municipal service is going to be, you get anxious. What if the local bus drives straight past, unable to pick you up because of this huge, throbbing airconditioned landwhale is unloading its cargo of bemused, earphoned tourgroupistes onto the one person wide sidewalk? It was chaos I tell you.
Eventually things sorted themselves out and the #7 arrived and we boarded within our permitted 90 minutes. It was a struggle for the bus from there but we just sat and observed how the usual dramas of urban life unfold. An MVA involving another bus, a BMW and a motorscooter, closing three of four lanes. A delivery van, double parked, while urgent packages are rejected for damage incurred while dealing with … a sudden intervention by several varieties of cops (carabineri, local plods, security company wannabes) misdirecting – an ambulance with the horrible wailing siren, unique to their kind, makes all thought impossible. Daily life in Florence.
We got there. Roman ruins were seen. The difference to Etruscan ruins was noted. Lombard burials were studied in minute detail. The play of mottled sunlight on Tuscan hillsides was dutifully recorded. Lunch was eaten, beer was drunk, Fiesole was given its due. Time to return. The #7 is waiting in the square but somehow some other distraction means that it has – how sad – circled the roundabout and gone back down the hill, without us. We find a bench in the shade, where we can wait the quarter hour that must elapse before another #7 will appear. And as we sit observing the human life around us, we note the numbers of others who place themselves between us and the bus stop. There is no orderly queue. The bus has three doors, and all are fair game for entry. And the capture of the very few seats – let alone those that face forward and allow a view out of a window – requires strategy and cunning.
When the bus does arrive, two schoolgirls nip aboard and occupy the seats designated for those over 65 – to which I am entitled and feel that I have earned, being at the bus stop a full 15 minutes before they appeared. My partner deals with the smart cards (proximity reader not being proximate to the desired seats). They get the window seats and pretend not to understand my protests.
But all is well and we are seated, if not optimally at least satisfactorily, and eventually the girls get off and we can arrange ourselves … wait, what, some scruffy individual, wants to inspect my ticket?? No uniform, no apparent authority?
It seems when the “smart card” was waved in front of the reader, no new ride authority was actually established. My partner’s card is fine, mine despite its three ride validity remaining is deemed “expired”. FIFTY EUROS cash to expunge the offence, once the details of the UK passport I carry with me to get free entry into National Monuments (but not, be it noted Fiesole Museums or archaeological sites) are copied onto a three part, no carbon required, form. He even digs into his clothing and produces photo ID which shows that he is actually the Yoda of ATAF – so there is no point in arguing – and a new crisp €50 note saved for “a rainy day” is handed over. The alternative is not worth contemplating. The shame, the publicity, the headlines. Far better to sign on the dotted line on a form – being Italian – that I have no hope of understanding. Your card reader, ATAF, failed but I must pay the price, or face ignominy.
I note, from a distance, that once again the Compass card is under assault. That Cubic is once more fair game in the fare evasion/faregates/fare or foul fraud foofooraw. Meh! Life goes on. I will be back next week, refreshed. Able to sleep all night and function on Pacific Summer Time. This too will pass.
