18.1. Source data | |||
A sample survey carried out by NIS is used for road freight data collection. Data on vehicles, journeys and goods transported are provided by the transport operators for the vehicles selected in the sample online through NIS e-Survey Online Portal or on paper to Territorial Statistical Offices. Sampling register used in the survey Name of register: Vehicle Register Name of organisation who maintains the register: Romanian Road Authority Frequency of update: Quarterly Frequency of access to draw the samples: Once a quarter Arrangements for accessing the register: The sampling frame is based on the information on authorised vehicles received quarterly from Romanian Road Authority. The scrapped vehicles reported by owners and the vehicles older than 25 years are not included in the sampling frame. Information obtained from the register: Number of registration, type of vehicle (category of vehicle and subcategory of vehicle), year of manufacturing, maximum permissible weight, load capacity, number of axles of vehicle (single vehicle), name and address of the vehicle's owner. From NIS statistical registers is obtained the information on main activity of the owner of the vehicle (NACE Rev2). The information is updated by the transport operator while filling in the questionnaire. Used in stratification : Type of transport (derived from NACE Rev 2), load capacity. Procedure for reminders: Reminders are transmitted by email at one week, respectively two weeks after the reporting deadline. After the second reminder the respondents are contacted by phone. The response rate is adequate. |
|||
18.2. Frequency of data collection | |||
The survey is carried out throughout the entire year and all 13 weeks of each quarter are covered. The vehicle (the statistical unit) is selected in the sample once a year for one week. Annual data are summed up from the quarterly data. |
|||
18.3. Data collection | |||
Sampling methodology Statistical unit: Tractive vehicle Types of units excluded: Vehicles with load capacity less than 3.5 tonnes, military vehicles, vehicles of public administrations, agricultural vehicles and vehicles older than 25 years. Time unit: 1 week Time units of the quarter included in the survey: All (13 weeks) Stratification: The sample is stratified according to the following variables:
Recording of weight of goods: Gross weight of goods is collected, i.e. containers swap bodies and pallets are excluded. Recording of journey data sent to Eurostat: Single stop: For journeys with more than one commodity, only one record is created. Journeys with the same distance, same goods, same quantity, same place of loading and unloading are recorded on a single row in the questionnaire, mentioning the number of identical journeys, but in A2 are recorded all journeys. Multi stop: Multi-stop journeys are recorded by vertical stages. Calculations of weighting factors
N = total number of vehicles in a stratum n = number of vehicles selected for the sample where: nh1 = number of vehicles with activity from stratum h nh2 = number of vehicle without activity from stratum h nh3 = number of refusal from stratum h nh4 = number of vehicle with uncertain activity from stratum h Optional variables covered: A1. Vehicle-related variables:
A2. Journey-related variables:
A3. Goods-related variables:
Additional variables collected compared to the legal requirements: Environmental impact-related variables: Quantity of fuel (low quality of data). |
|||
18.4. Data validation | |||
National level : The first level of checks and validation are performed at Territorial Statistical Offices level and the second/final level of checks and validation are performed by NIS, according to the provisions in Order of the President of the National Institute of Statistics of Romania setting the methodology for the production of goods road transport statistics. From Eurostat : Since 1999, micro-data from the reporting countries have to be submitted according to Commission Regulation 2163/2001. The data are then checked and validated by EUROSTAT (verification of many different codes used (NUTS 3, numeric or alphabetic variables) correctness of linked questionnaires in the different dataset, etc…). Detected errors are then reported back to the data sender with the request for correction, this is an iterative process until at least 99.5% of all data records are validated and loaded in the database. |
|||
18.5. Data compilation | |||
The quarterly micro-data are processed, edited and validated, than extrapolated on the basis of weighting factors in order to obtain quarterly data. |
|||
18.6. Adjustment | |||
Road freight data are not seasonally adjusted. |
