We had a presentation from Mark Wagenbuur, who is the blogger of Bicycle Dutch. he provided an interesting perspective on Dutch cycling starting from the 1950s, it was the same as it was today. Cars were there in the 1950s, there was money and people able to afford the cars after WWII. As the country prospered, congestion increased and the parking was also congested. In the 1970s, it was similar to the U.S. with traffic engineers planning the cities. An overview of his presentation is available here.
The presentation focused on how the Dutch got great cycling infrastructure starting back in the 1950s, where after WWII, there was a need to get back to moving freely after the Nazi occupation. Yet, there was also a growing automobile culture, that was partially halted by the oil embargo of 1973. This and the rise in fatalities of people and especially children were other motivating factors. This made way for protests in the streets of Amsterdam in 1975. Several examples were given of protests.
We want a SAFE Street - Wij Willen een Veilige straat.
Stop murdering children, safe footways and cycleways - Stop Kindermoord
Autorijden? Ga Nou Gauw Fietsen - Protest rides all over the country.
Cyclists Union was founded in 1975. The lonely cyclist struggles ahead, but no longer alone.
The community demanded genuine cycling policies and the resources to go with the change. The Cyclists Union wanted the government to give cycling a true role in the policies. There were two specific demands:
Separate slow and fast traffic (bike and motor)
Give cycling free routes through towns.
There was already a law on the Dutch government that says if you have more than 500 cyclists per day, you have to have separate cycling (rural conditions). So, in the 1970s this was a good place to start and he described the three strategies as:
Elimination of through traffic
Removal of parking
Prioritization of bus lanes
He then described the three simple requirements for mass cycling?
A bicycle
Parking on both sides of the trip
Good cycling infrastructure
In describing the standards for a bicycle, it has to be sturdy, upright, (could be heavy), chain case, fenders, wheel dynamo (no batteries), lock, etc. The parking has to be located well, the government mandates that the parking is indoor (ideal and now a requirement), with easy access to the street and where you don't have to carry it (remember it is a heavy bike).
Finally, Dutch design for good cycling infrastructure includes careful planning of the space in the City. Designing for people is key and auto traffic flow is secondary. There are planning policies that are used.
This is a particular example of those policies and how to move people in cities.
Bus stop and cycletrack design are great examples in The Netherlands. What they know is that bike lanes are not good enough. He wants protected intersections to be the main stream like it is in The Netherlands. The other important element of Dutch design is that the speed of the street is 50 km/hr speed limit for all streets with people cycling. Higher speed does not work without supporting infrastructure. In Houten, when there was a street design that was 100 km/hr and the police was asked to enforce a 50 km/hr speed limit, the police stepped in and decided to ask engineers to solve the problems. Engineers were set up a traffic calming function on the request of the City police. Police can't accomplish their job, if the design isn't supported.
The policies that have been used in the history of cycling include the following:
Dutch Bicycle Master Plan 1990-96 only time federal government has focused on the issue.
Sustainable Safety policy 1990-now
Design Manual for Bicycle Traffic (CROW) generally followed by municipalities.
The Dutch are very strict on their use of a road categorization that requires designation and there are three main classifications.
Through regional routes 130 to 80 km/hr - no cycling
Local distributing - collector roads - 50 km/hr - depending on traffic you would have physical or visible spearation (bike lane) - collector roads can not have parking or destinations.
Residential streets/places - Speed 30 km/hr (18 mph), no separation is needed.
Some municipalities have fought for a hybrid extra (destinations are the typical element that is added).
He used Houten as an example designed in the late 1960s as a cycling friendly city. Red lines can not be crossed by motor traffic. ring road all around the city, that provides circulation into the different parts of the City. Cyclists can not go anywhere. Cycling is almost always faster than the car.
He used Houten as an example of how to retrofit existing residential areas
1. Block off streets, narrow other streets with traffic calming.
2. 18 exit/entrance biking, 3 for cars (provide more options for bikes to avoid traffic)
He also cited that the Dutch closed down traffic on a Sunday as an experiment for placemaking in city centers
Where did the cars go? In the City Center of Utrecht, changes were made so it was impossible to go through the City. Now, the traffic stays out on the fringes. No through traffic in the main area. Simple fences were used and buses allowed through. Cameras are providing the enforcement.
Downgrading former arterials are key to the implementation
Traffic dispersion happens, but don't worry about chasing all of that traffic.
What can other countries learn? They should do the following as others are working on this issue too:
Placemaking is happening.
Complete streets, including cycling infrastructure
Protected intersections
Designing a network.
Placemaking - Prague, Paris, and NYC
Complete streets - Sydney, Chicago
Protected Intersetions - SLC, Davis, Austin, and Boston.

What do Advocates Do? Jeff Rosenblum, Livable Streets
As a trained engineer who became an advocate, then City bureaucrat, and now Ph.D. candidate, Jeff has a vast experience of what makes a city tick and how change happens. He has some great takeaways from his time creating Livable Streets, describing "What Advocates Actually Do?", he boils it down to three points:
Jeff has some great examples also of specifics.
Build bike rides that start people thinking about riding bikes in the City - Boston Hub on Wheels Citywide ride & festival
Building constituency
Lawsuits when necessary - reconstruction projects must accomodate bikes and pedestrians to the best practicable. Only person doing the suing - Attorney general
When government is no longer the problem, organize a Bike Summit, pick a project to get started on. Make the engineers be the heroes by helping them get project designs correct. Make planning effective by prioritizing the connections that are most important.
Also, I will add one more that he said: Thank bureaucrats when they do the right thing
- Convince government to do it
- Provide technical assistance
- Build grass-roots support for projects
Jeff has some great examples also of specifics.
What specifically do Advocates do?
They build relationships with magazine editors - Bicycling Magazine puts Boston on the worst cities for Cycling.Build bike rides that start people thinking about riding bikes in the City - Boston Hub on Wheels Citywide ride & festival

Lawsuits when necessary - reconstruction projects must accomodate bikes and pedestrians to the best practicable. Only person doing the suing - Attorney general

5 Misconceptions in Transportation by Jeff Rosenblum - Livable Streets
I will start with the takeaways instead of the misconceptions, because not everyone will read the entire blogpost and the talk was really positive, but he used the misconceptions to drive the conversation for the students. He also described his role as an advocate which is a separate blogpost altogether.
- Streets are for people
- Cars need less space
- Traffic calming works
- Decisions are political
- Economic growth relies on livable streets not more highways.
1. Streets are for cars
- Streets that are busy for 15 minutes a day
- Place where no one wants to walk, no cafes
- People used to use streets as part of their living environment - today 75% of place that children are free to roam has been compromised by automobile
- Jeff used the example of a Dutch school drop off, paint being used in NYC, and Portland street paining at SE 34th & Yamhill.
- European cities were not always the way they were. Amsterdam in the 1950s was moving toward car ownership, but they saw the way the U.S. was going and reoriented toward bicycle. Delft Center used to be a parking lot. NYC and Broadway is another example. Anytime you can take place in a city, you're making livable streets. Parking Day is a great example of this, founded in San Francisco.
2. Cars need more space
- Reducing congestion is not a goal for cities. Massachusetts Avenue road diet occurred in 1996. There is time and space. Don't let the number of lanes fool you! It isn't about just space, there's also the time component. Preventing left turns, retiming traffic signals, etc are all strategies that have to be part of the conversation.
- Not enough parks, take space from parking or on-street traffic
- Lafayette Square was rebuilt in 2008 as an example of remaking a crosswalk into a park.
- Western Avenue in Cambridge there was a cycletrack of 9 feet wide with a 7.5' parking, 10.5' travel lanes and another 7.5' parking. The speed limit is 30 MPH in Massachusetts, but 25 MPH is on Western Ave. Bus bulb outs are part of the cycletrack, eliminating parking.3
3. Traffic calming is the most important thing that engineers can do
- Pasanen (1992) http://tinyurl.com/yuohsg - NHTSA study
- Traffic engineers have the tools at our disposal and we need to use them
4. Decisions are technical
- USDOT Ray LaHood started the dialogue related to considering additional flexibility. The Green Book even provides the following: "the intent of this policy is to provide guidance to the designer by referencing a recommended range of values..., sufficient flexibility is permitted to encourage independent designs tailored to particular solutions."
- NACTO
5. Cars drive the economy
Jeff used the example of Interstate 95 coming into Charles River. One of the Livable Streets founding Board Member was going to have his home demolished and have a highway that comes through the Northeastern University campus.
McGraff highway in Somerville is an example of an antiquated highway that is going away. It takes concentrated efforts to think differently about the
Kendall Square Example
Parking TDM policy "pays off" - no more than 45% or people drive themselves. If they don't have less than 45%, the building gets shut down. Clean Air Act and parking freeze. Self reporting happens once a year and the City gets to check how it is going. The City provides an ala carte menu of things.
The success has resulted in great model for the City to follow when large projects occur.

Left Turn Options at Traffic Signals
Two stage queue boxes are an area designated to hold a queue of people waiting to finish two stage turn manuever. To use this design, a person would remain in the bike lane and veer right, turning their bike to orient towards making the turn.
Two stage queue boxes are not used very often in the Netherlands due to the nature of how many cycletracks they have throughout the country. During our study of traditional bike lanes used in the City of Delft, we found this intersection where the left turns at the traffic signals is made from the left turn lane shared with cars. The detection of the people on bicycles is done with a conveniently placed push button adjacent to the curb. There is the maintenance concern with a pole placed that close to the curb, but that short pole with the button is before the curve, so with a low volume left it may not be a problem. I am not clear why they felt the need for a button as opposed to having an inductive loop detector, which is used throughout the City in other places. The other element of the traffic signal in this particular location was that they have a nearside signal head for both the vehicles and the cars. It is a supplemental head mounted adjacent to the pedestrian push button.

| This traffic signal pole is used for the supplemental nearside left turn signal indication, the pedestrian push button and both vehicle signals (larger displays). |
The farside traffic signal provides an arrow underneath a bicycle symbol to clariy what the person on a bicycle should do upon getting the green.
The left turn queue box is staged in front of the side street through and left turn movement in effect blocking that movement so that the person on the bike can be at the front of the queueand not incur delay . It operates like a bike box without the lead in lane.

Rainbow Crosswalk in Utrecht
A visit to Utrecht provided a pleasant surpise in the form of color on the street at a crosswalk.
In addition to the rainbow crosswalk, there is a diagonal crossing for a movement for people using bicycles. This diagonal crossing provides an opportunity to eliminate what would be a two stage crossing in Denmark or most other cases. It takes advantage of the fact that there is a long time necessary for pedestrian crossing perpendicular to this through bike movement.

Bike Box in Delft on Wateringsevest at Noordeinde
The bicycle box was a treatment that came from European traffic engineering practice. The Delft community does not have that many bike boxes, but this is one in the north part of town that is constructed in different colored brick. The street these cars are on is Noordeinde and the intersecting street is Wateringsevest.

Delft Bicycle Parking Garage
Delft recently reconstructed its train station. The train station was a lovely old building, dating from 1847 and rebuilt this past year (2015). The parking for 8,700 bicycles includes 5,000 underground immediately south of the train station.

| Start of the bike path to the underground parking |
The project included a 2.3 km tunnel under the city center includes a wonderful bike connection. The bike connection is on the east side adjacent to a canal and provides grade separation from the east-west crossings and a direct link to the underground bike parking.
![]() |
| Entrance to the parking garage - below grade of the main entrance but closer to the train level |
The bicycle parking information is fantastic with information available on how many spaces are available in each row of parking. In a garage with 5,000 spaces, the Dutch use numbering to help you remember where you parked your bike.
The number 2 is shown below (not quite as clear as the Utrecht garage) and this is the parking for oversized bikes including bakfiets.
