Traffic Simulation Update: Multiple Cars, Multiple Lanes

Posted on March 25, 2009 by Brad Heap

Okay, the traffic simulator project has been slow going over the past few weeks, just not been very focussed and playing with DLA and other assignments too much.

This morning/arvo I changed some of the code and layout of how cars were being generated. Now instead of a car know what road it is on it has been reversed, so each road has its own collection of cars to manage. With some changes to how the graphics are produced this now means that cars are now rendered at the same time as each road. A that allows perfect placement of cars onto roads rather than having to do a mathematically approximation. Clear as mud?

6000 Point Balanced DLA

Posted on March 24, 2009 by Brad Heap

Yes I am still making DLAs just trying to make the maths that little bit nicer, and get that all impressive performance boost.

This is a 6,000 point balanced model, it took just under 1.5 hours to generate, compared to 4+ hours for a 5,000 point unbalanced DLA on Sunday

This is the next 10 months of my life:

Traffic Simulation

Purpose:

To construct a real time three dimensional simulation of congested traffic flows in Java and to test various ideas surrounding the build up of congestion.

Such tests may include but are not limited to:

Testing various algorithms for effectively navigating already congested traffic in the shortest amount of time
Testing algorithms to determine the best approach to reduce the build up of congestion
Investigating the impact of various events such as an accident, construction of a new road or lane on the amount of congestion in the model.

Expected Outcomes:

Project constructed in object orientated and model-view-controller code in Java
Use of Open GL or other three dimensional rendering tools
Interactive GUI allowing end user to construct traffic model
Ability to import satellite images in standard JPEG format to be used as ground textures.
Road network data structure to be based on Graph Theory
Cars implemented as artificial intelligence agents with real world physical control models, collision detection and awareness, environmental awareness.
Ability to perform controlled tests on simulation, including testing of algorithms for avoiding congestion once built up, algorithms for avoiding congestion build up, and impacts on varying road network design and events on traffic flows.
Ability to extract data and results from the model.

Universal Living Allowances

Posted on July 25, 2008 by Brad Heap

There has been a lot of noise in the media recently about Universal Living Allowances for all students.

I am a strong believer in the fact that you go to University to learn and get an education that will better you and the country. I do not believe that you should have to distract yourself away from studies to do part time work to support yourself financially. If the Government wants an knowledge economy of the future they must first fund it.

What I propose is a Universal Living Allowance for all fulltime students as follows:

To qualify you must be enrolled as a fulltime student in a course with a minimum length of 6 months.
The student allowance rate should be set at the same amount as the dole.
Once you have completed your first year on the USL you can only qualify for subsequent years if and only if you pass 75% of your papers in your previous years.
USL should only be available to undergraduate and honours students. Any research driven post-graduate qualifications should be paid for through scholarships.
Only University and Polytech students in a recognised post-secondary course should be eligible.

Now I have no idea of how much this would cost. But this is what this country needs. Hand ups to those who deserve it, not hand outs to those that don’t.

Massey University dumps on International Students

Posted on July 7, 2008 by Brad Heap

Press Release: MASSEY UNIVERSITY STUDENTS’ ASSOCIATION FEDERATION

Massey University dumps on International Students

From 2009 all new International Students studying at Massey University will face an immediate 6 – 7% average increase in tuition fees and ongoing annual tuition fees increases due to a removal in fee Grand-parenting for International students.

Fee Grand-parenting of tuition fees for International Students ensures that students do not face tuition fee increases throughout their course. Massey University introduced fee Grand-parenting in 2005 to give International Students stability in their finances while they study.

“The decision by the Massey University Council last Friday to remove these protections for students’ financial wellbeing will severely hurt international students” says Albany Students’ Association (ASA) President, Brad Heap. “This decision was made entirely behind closed doors; students had no knowledge of this move and the University did not consult with a single student on the changes.”

“Massey University has decided to put profits before pastoral care of students and I find this disgraceful. You would expect the University to have a social conscience and protect their students not dump fee increases on them without consulting them,”said Heap.

MUSAF is committed to ensuring that the University treats all students as individuals and does not treat its International Students as ‘cash-cows’. MUSAF will continue to work with students across Massey University’s three campuses to ensure that the University actively consults with students and in the meantime urges Massey University Council to reverse its decision.

Student Debt Debated In The House

Posted on April 9, 2008 by Brad Heap

Go the Greens and New Zealand First! Good on you for standing up for students!

Tomorrow is going to be huge. Student Debt hitting 10 Billion is already in TV3 News as the third story, New Zealand Herald, Stuff, Scoop. And probably lots more.

9. Debt, Student-Increases

[Uncorrected transcript-subject to correction and further editing.]

9. METIRIA TUREI (Green) to the Minister for Tertiary Education: Has he received any reports that student debt will reach the milestone of $10 billion this week; if so, what, if anything, does he plan to do about it?

Hon PETE HODGSON (Minister for Tertiary Education) : Yes, I have. Next month’s Budget will contain some measures to further increase student support, just like each of our first eight Budgets have already done. I acknowledge in passing the Green Party’s consistent support for progress in this area, and I also acknowledge that the National Party has consistently voted against such progress.

Metiria Turei: Does the Minister stand by this statement, which he made in January of this year: “Each year under Labour-led governments student support has strengthened,”; if so, how does he reconcile that comment with the fact that the latest figures show that fewer students received a student allowance in 2006 than when Labour came to power in 1999?

Hon PETE HODGSON: The proportion of eligible students who are receiving the allowance now is well over half-it is about 57 percent-about three-quarters of whom are receiving the full allowance and one-quarter of whom are on the cusp, if the member might see what I mean. That is a great many more students than when we first came into office. I cannot express the difference in a percentage, however, because I do not have the figures with me.

Hon Mark Burton: In the light of the Minister’s response to the primary question, does he expect that total student debt will go on to reach $11 billion or even $12 billion; if so, why is the total debt still rising?

Hon PETE HODGSON: It is a very good question. The total debt continues to rise because, apart from inflation, there are more students, and more students are studying to a higher level. That is a good thing. It is a good thing. The question is what is happening in the life of an individual student, and what is happening there is that conditions continue to improve. They would say “too slowly”, but conditions do improve. The average debt is now rising more slowly than the average wage, with the average wage being the way that one pays the debt off. For that reason the average repayment of the debt has reduced from where it was in 2001, at 9½ years, to where it is now, at less than 6 years. So there is an improvement for students. The Greens have assisted with that improvement. We need to make more improvement.

Dail Jones: Does the Minister accept that the problem associated with student debt, with or without interest, can be substantially reduced by the introduction of New Zealand First’s policy, which for many elections has stated that New Zealand First will introduce a universal student allowance that does not require repayment?

Hon PETE HODGSON: Having a universal student allowance is the policy of a number of parties in this House. For my part, we are happy in our party to move towards, but not to, a universal student allowance, and this is why: I have other priorities. I need to pay attention to the quality of tertiary education. I need to ensure that the completion rates continue to rise. I need to ensure that the access-especially for Māori and Pacific Islanders, which is well below par-must be increased. These things all cost money and I happen to place them above the move to a universal student allowance. On the other hand, we make progress towards that universality in most years, and I hope we may do so again next month.

Metiria Turei: Does the Minister disagree, however, that his inadequate student support policy, which includes interest-free student loans, has actually led to a 9 percent decline in the enrolment of students from poor backgrounds; and will he then make a real commitment to fulfilling the policy of the Green Party, the New Zealand University Students Association, and, obviously, New Zealand First, for having a universal student allowance, which would ensure that today’s students are able to have the same opportunity to learn, to buy homes, to choose when to have families, and to take control of their financial destiny, as he and most of the Labour Party leadership have also been able to do?

Hon PETE HODGSON: The short answer is no. I have no advice to the effect of a 9 percent reduction in whatever the member suggested might be occurring for New Zealanders who are from more modest backgrounds. On the contrary, there is documented evidence of higher access for Māori and Pacific Islanders, but not high enough, and of higher completion rates at level 7 and above, but not high enough. We have had some dramatic, outstanding improvements in education amongst Māori and Pacific Islanders in the tertiary sector in this country-especially in the years 2002 to 2006, which is the latest data available-but I would be the first to say, along with all of my colleagues, that progress is not yet sufficient.

Dail Jones: Is the Minister aware that student debt can begin to be decreased by increasing the current parental income maximum for a student allowance from $71,000 before tax, if one lives in a parental home to study, and just over $77,000 before tax, if one lives away from a parental home-the current rate-to, say, $100,000 before tax, if one lives in a parental home to study, and $105,000 before tax, if one lives away from a parental home, which would cost an estimated, and I emphasise “estimated”, additional expenditure of about $300 million to the Government, and surely this would be a good investment in education and in the future of New Zealand and it would encourage qualified people to stay in New Zealand?

Hon PETE HODGSON: Yes, I am aware of that, which is why, although the member was not able to be with us, this Government shifted parental thresholds three times in each of the last three Budgets-by 20 percent, 10 percent, and 10 percent-and we do not rule out the possibility in the future of a further shift in the thresholds.

Metiria Turei: Is the Minister aware that the Minister of Finance recently told the TaxAgents’ Institute: “We have real ambition for New Zealand and our economy. And we know that by refusing to burden our children and grandchildren with a legacy of debt, we are removing one of the biggest obstacles to realising that ambition.”; if so, does it worry him that the Minister of Finance is so ignorant of the $10 billion legacy of student debt left by this and previous Governments, which has a proven, disproportionate exclusionary impact on women, Māori, and the least well-off New Zealanders?

Hon PETE HODGSON: Just a couple of comments in response: first, the level of participation of, say, New Zealand Māori in our universities is still below that of, say, New Zealand Europeans, but it is getting better, not worse. The member shakes her head-she needs to go back and look at the statistics. Second, I did not have the pleasure of being in the room when the Minister of Finance made his quoted remarks, which is a shame, of course, but I would not mind betting he was talking about KiwiSaver, and that is a magnificent policy that will change the face of this country.

Metiria Turei: I seek leave to table a chart showing that the numbers of students receiving an allowance in 2006 are 5,000 fewer than in 1999.

* Leave granted.

Metiria Turei: I seek leave to table an article describing how the under-35s are now effectively shut out permanently from financial security.

Madam SPEAKER: Leave is sought to table that document. Is there any objection? There is objection.

Metiria Turei: I seek leave to table “Freedom from debt, freedom to prosper”-the Minister’s speech to the TaxAgents’ Institute of New Zealand given in March this year.

* Leave granted.

Dail Jones: I seek leave to table a document to introduce a universal student allowance, being New Zealand First’s election policy.

* Leave granted.

More Photos From The Top Of The North Island

Posted on April 3, 2008 by Brad Heap

Just got some more photos taken by other people who also summited Ruapehu a few weeks ago.

This is the group of us at the start of the day.

This is about an hour in. That hill in front of us will only take about another hour to get up. And then what you can’t see is on the left the next bit that is that high again.

People so small. Rocks, Cliff so large. This is nearing the top of the valley that is in the above photo.

Just a stroll up a hill.

Party at the top. Pun intended.

Walking across the Ash Field.

Going down with the weather packing into the valley below. See all the ash between the rocks. This made the descent extremely difficult triple checking footing.

It is only a little bit further to the bottom.

Weather getting nice and dark near Knoll Ridge (top of Whakapapa Ski Field) an hour from the bottom.
