Drivers of heavy vehicles un-supported by Safe Journeys

For truck drivers, an 80 km/h speed limit has the potential to save at least 20 to 32 lives per year

Improving the safety of heavy vehicles – What is the problem?

Safer Journey Strategy page 28

  • In 2008, crashes involving heavy vehicles (HVs) accounted for 18% of road deaths and 9% of total injuries. This equates to 65 deaths, 258 serious injuries and 1,144 minor injuries.
  • About 80% of people killed in heavy vehicle-related crashes are other road users.

Table data from Quarterly road toll report Jan 2017 to Mar 2017

What has Safe Journeys improved for drivers of Heavy Vehicles (HVs) in New Zealand?

In 2010 HVs were involved in 71 of 379 deaths (18.7%)

In 2017 HVs have been involved in 91 deaths (rolling 12 month) of 332 annual road fatalities: 27% of road deaths.

Benchmark this against the 2016 German crash facts.

German drivers of HVs suffered 137 deaths out of 3,155 persons killed on German traffic: 4.3% of road deaths.

There are a lot of trucks on German Autobahns, but there also helpful safety rules.

The Autobahn has an advisory speed limit of 130 km/h. While going faster is not illegal, in the case of an accident, the driver is deemed at least partially responsible due to “increased operating danger”.

Vehicles with a top speed of less than 60 km/h are not allowed to use the autobahn.

For HVs (Goods Vehicles) over 3.5 t the maximum speed is 80 km/h. In New Zealand it is 90 km/h. Wiki Speed limits in Germany

Countries where the maximum  speed is 80 km/h for ‘Single carriageway’: China, Demark, Finland (winter), France (rain), India, Japan, South Korea, Taiwan.

Countries where the maximum speed for trucks is 80km/h or less: Argentina, Brazil, Czech Republic, Denmark, Finland, Germany, Greece, Hungary, Israel, Italy, Japan, Malaysia, Netherlands, Norway, Peru, Philippines, Poland, Portugal, Singapore, Saudi Arabia, South Africa, South Korea, Spain, Sweden, Taiwan, Thailand, Turkey.

Wiki Speed limits by country

“ If open road mean speeds dropped by 5 km/h, 60 lives per year would be saved” (Page 22, safe systems) Safer Journey Strategy

To repeat: for truck drivers, an 80 km/h speed limit has the potential to save at least 20 to 32 lives per year.

Parking Building Economics

Posted on by 1 comment

If the value of a car parking space is greater than the cost of supplying the car parking space then private investors will provide parking. Should politicians use ratepayer or/and taxpayer money to subsidize and/or oversupply car parking, the value of a car parking space will fall, but the cost will not.

This post is based on parking building economics as explained in 1973 as an appendix to the Traffic management plan for Hamilton.

To try make this relevant in today’s money the Value in [$—] is in today’s money as per the Reserve Bank Inflation calculator, using the following settings.

Parking Building Economics

The following is an approximate estimate of the economics relating to the construction of a 500 car parking building within close proximity to the city centre as suggested in the Transportation Study Planning Report.

  1. Cost

(a) Capital Cost

A parking building will cost about $2,500 [$31,030] per car space (excluding land). A 500 space building would therefore cost $1,250,000. [$15,515,845]

(b) Operating Costs

It is envisaged that operating costs and costs for such items as maintenance, lighting and insurance would be in the order of $75,000 [$930,950] per annum.

(c) Annual Costs

Annual cost of a building would be:-

Loan Charge and servicing (10% p.a) $125,000 [$1,551,584]

Operating Costs                                        $75,000 [$930,950]

Total $200,000 [$2,482,535]

  1. Revenue

The revenue required for a building to be self-supporting with an annual cost of $200,000 [$2,482,535] would be approximately $1.60 [$19.86] per space per day.

To collect $1.60 [$19.86] per space per day, based on a 10-hour day and a maximum operational occupancy of 80%, it would be necessary for the parking charge to be 20c [$2.48] /hour

Note that the existing Central Car Park has an occupancy of 65% and revenue of 45c [$5.59] /space/day (1972/73 receipts)

Now in the real world of this century some of the above costs are not like-for-like:

(1)   The VALUE or COST per car space this decade is more like a third less at about $12 or $20k, giving a 500 space building a cost of $6 or $10 million. – source

(2)   The Annual Cost of servicing a loan at (6% p.a.) = $360k or $600k plus Operating costs of $930k = Total of $1,290 or $1,530k divided by 500 spaces = $2,580 / $3,060 per space per year.


(3)   Revenue needed to service a loan of $2,580 or $3,060 per space per year is $10.32 or $12.24 per day. (Based on 250 days)

To collect $10.32 or $12.24 per space per day, based on a 10-hour day and a maximum operational occupancy of 80% it would be necessary for the parking charge to be $1.29 or $1.53 per hour


This is pretty close to the cost of parking at the Knox street Parking building.
