5. Introduction
 Transportation planning, or transport planning, is involved with the
evaluation, assessment, design and siting of transport facilities (generally
streets, highways, bike planes and public transport lines).
 It is carried out to address several statutory requirements ( planning
permissions, EIA, EIS, etc) and the assess the suitability of land to be developed for
clients
 The evaluation, assessment, design and siting of transport facilities is usually carried out
using a Traffic Impact Assessment (TIA) or Transport Assessment (TA).

6. Introduction
 The TIA ‘process’ consist of 3 fundamental steps:
 The determination of the need for a TIA
 The scope of the TIA
 The preparation of the TIA itself
 A TIA should normally be produced where either of the following conditions are met:
 Traffic to and from the development exceeds 10% of the two-way traffic flow on
the adjoining highway.
 Traffic to and from the development exceeds 5% of the two-way traffic flow on the
adjoining highway, where traffic congestion exists or will exist during the
assessment period.

7. Introduction
 The format of the TIA depends on the complexity and size of the proposal, any Local
Authority requirements and the type of permission sought.
 A typical contents page would be as follows:
 Non-Technical Summary
 Existing Conditions
 Proposed Development
 Modal Choice/Trip Attraction
 Trip Distribution
 Assignment of Development Traffic
 Assessment Years
 Highways Impact
 Internal layout (Parking Provision, Pedestrian/ Cyclists/People with
Disabilities/Public Transport)

9. A Review of Local Transport Plans
 An understanding of Local Transport Plans is vital to ensure a robust TIA is presented to
the Local Authority
 Key information that is included in Local Transport Plans include:
 Car parking standards
 Cycle parking standards
 Road geometry standards

10. A Review of Local Transport Plans
- Parking Provisions
Residential Cycle parking Car Parking Servicing
Dwellings standards (minimum) Standards Requirements
(Use Class C3) (maximum)
Norwich (Link) One covered and secure cycle 1 and 2 bed units: 1 space per dwelling Access for emergency services,
storage space or shed per dwelling. 3+ bed units: 2 spaces per dwelling. removal lorries, refuse vehicles
On average, developments should will be necessary.
Cycle parking for visitors is required average 1.5 parking spaces per unit or
in the vicinity. fewer.
Herefordshire – One l/t space provided per dwelling 1 bed: 0.75 space per dwelling Access for emergency services,
Welwyn Hatfield if no storage or shed is provided 2 bed: 1 space per dwelling removal lorries, refuse vehicles
(Zone 1 & 2) (Link) 3 bed: 1.5 spaces per dwelling will be necessary.
4 or more: 2 spaces per dwelling
Wiltshire Council Not available 1 bed:1space per dwelling Access for emergency services,
(Link) 2-3 bed: 2 space per dwelling removal lorries, refuse vehicles

15. Design and Construction of Roads to Adoptable
Standards – Road Specifications
 Each Local Authority has its own specifications
 Each Local Authority has its own specifications
 Manchester
 Hertfordshire
 Road geometry standards
 These are substantial documents which provide specifications for road build-ups to
adoptable standards. Useful for:
 Clients
 Contractors
 QS

16. Design and Construction of Roads to Adoptable
Standards - Road Specifications
 The elements of the road pavement construction are
 Sub-grade (or capping if laid) - This is the foundation on which the road
construction is built;
 Sub-base - Is a layer of granular material that is laid on the formation;
 Base- Is a layer of bituminous material laid on the sub-base. Base material with an
aggregate size greater than 28mm is not acceptable;
 Binder Course - is laid on the base. With certain materials it is possible to combine
the binder course and base layers; Manchester
 Surface course - provides the running surface of the carriageway. In certain
circumstances, block paving is used instead of bituminous surfacing and binder
course.
