Presentation outline

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).

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.

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)

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

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:

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.

Design and Construction of Roads to Adoptable Standards - Road Specifications

What Pinnacle can offer our Clients





A review of existing conditions to advice client of following: Review of existing local road and footpath network Review of existing local public transport network Pre planning meeting with relevant Stake Holders Proposed scope of junctions to be assessed in the TIA Commissioning of classified traffic counts


A review of existing conditions to advice client of following: Review of site in terms of site access/egress i.e. positioning of access/egress,

sight lines, geometry Review of internal site layout using AutoTrack Planning search for other committed developments


Modal Choice/Trip Attraction: Use of TRICs database to determine at what rates vehicles arrive/depart the site


Trip Distribution: Evaluate trip distribution of trip attraction to determine AM/PM peak period of

site Advice client on demand led car parking requirements Put forward an argument to Local Authority if the demand led car parking

requirements/actual provisions differ to that of the Local Authority provision (max/min standards often stipulate in LAP)


Assignment of Development Traffic Assignment of development traffic to local network


Assessment Years Determination of opening year and design year in accordance to relevant

standards i.e. IHT Guidelines for Traffic Impact Assessments Determination of network growth factor to take into account the increase of the

national fleet local (which is then applied to traffic surveys)


Highways Impact Determination of the impact the development will have on the local highways

network using the following: OSCAD ARCADY PICADY LinSig

We also have access to more sophisticated computer software programmes such as:

VISSIM VISSUM COBA SATURN


Internal layout (Parking Provision, Pedestrian/ Cyclists access People with Disabilities Public Transport Refuse/Fire Tender access (AutoTrack) etc
